Legumes give nitrogen-supplying bacteria special access pass
December 2011
A 120-year debate on how nitrogen-fixing bacteria are able to breach the cell walls of legumes has been settled. A paper published by John Innes Centre scientists, with Professor Allan Downie as the lead author, reports that plants themselves allow bacteria in.

Once inside the right cells, these bacteria take nitrogen from the air and supply it to legumes in a form they can use, ammonia. Whether the bacteria breach the cell walls by producing enzymes that degrade it, or the plant does the work for them, has been contested since an 1887 paper in which the importance of the breach was first recognised.

"Our results are so clear we can unequivocally say that the plant supplies enzymes to break down its own cell walls and allow bacteria access," said Professor Allan Downie.

Tuberculosis drug target's structure to point to new therapies
November 2011
Scientists at the John Innes Centre led by Dr Stephen Bornemann and Dr Dave Lawson have worked out the structure of a class of enzyme that has been genetically validated as a new drug target in Mycobacterium tuberculosis, a pathogenic bacterium which is responsible for 2 million tuberculosis deaths worldwide each year. The scientists have been awarded over £500,000 by the Biotechnology and Biological Sciences Research Council (BBSRC) to work out how this enzyme works and is regulated, which will help in the development of new therapies against tuberculosis.

How parasites modify plants to attract insects
November 2011
Scientists, including Dr Saskia Hogenhout, from the John Innes Centre on Norwich Research Park have identified for the first time a specific molecule from a parasite that manipulates plant development to the advantage of the insect host.

"Our findings show how this pathogen molecule can reach beyond its host to alter a third organism," said Dr Hogenhout.

Microbiology to play crucial role in ensuring food security
November 2011
Professor Mike Peck of the Institute of Food Research has joined other experts from the Society for General Microbiology in launching a position statement on food security and safety. This sets out the key role that microbiology will play in ensuring that the 7 billion people in the world have access to safe and nutritious food.

"Food security and safety is concerned with the production of sufficient safe food for all. The world is already experiencing a food security and safety crisis. These problems are likely to be exacerbated by the increase in the global population expected in the next few decades," said Professor Peck.

Scisense - Student Science Magazine

New NRP science magazine "Scisence" launched
October 2011
A group of PhD students from the John Innes Centre, The Institute of Food Research and the University of East Anglia have got together to launch a new science magazine "Scisense". The magazine, which is currently published electronically, http://www.scisensenrp.co.uk, is designed for students and is intended to promote the ground-breaking science taking place across the Norwich Research Park and across the world. The first issue includes articles on antibiotic research in the labs of Mervyn Bibb, Matt Hutchings, and Tony Maxwell as well as an interview with Professor Jon Clardy from Harvard Medical School.

Combase and the NHM

Night at the museum for IFR scientists
October 2011
Combase, the predictive microbiology database co-ordinated by IFR, was recently showcased to a public audience at the Natural History Museum in London, at an event designed to let people get hands-on with cutting edge science and meet the people behind it.

Marina Munoz-Cuevas and Olivia Csernus (pictured on left), who work in Dr Jozsef Baranyi's research group at IFR, demonstrated the Combase system to hundreds of museum visitors on the night. The Combase database contains collections of data relating to how various food-borne microorganisms survive and grow in different food materials. The database is therefore incredibly valuable to food processing and packaging companies, who can consult it to ensure that their production lines and practices are safe.

Salmonella

Researchers to identify the secrets of Salmonella's survival
October 2011
IFR researchers are to investigate how Salmonella survives during its lifecycle within our bodies, as a way of finding chinks in its armour that can be exploited to develop new therapies. The researchers have been awarded over £400,000 by BBSRC to work together with colleagues at the University of Sheffield to identify the different ways in which Salmonella obtains its energy for growth and survival within the two types of host cells.

Once inside our bodies, Salmonella invades the epithelial cells that line the gut and reproduces, and can become systemic by invading and growing in macrophage cells, which are part of the body’s immune defences. "We inferred that Salmonella uses different pathways to generate the energy required for growth and survival in macrophages and epithelial cells," said Dr Arthur Thompson. "What we want to do now is work out what these pathways are. Does Salmonella use anything from the host cells to contribute to its growth?"

The Genome Analysis Centre (TGAC)

Crowd-sourcing the E. coli O104:H4 outbreak
September 2011
Ten variants of the deadly Escherichia coli strain that hit Germany in May 2011 have been sequenced across the world. The unprecedented level of collaboration across the scientific community should give insight into how the outbreak arose, says a scientist at the Society for General Microbiology's Autumn Conference 2011.

Sequencing of the bacterium started in early June at BGI, China. Their sequence was provided in draft form to the scientific community as a crowd-sourcing project. This allowed scientists, including those at The Genome Analysis Centre (TGAC) in Norwich to identify key disease-causing genes. Dr Lisa Crossman, Microbial Genome Project Leader at TGAC, explained, "We have found that the strain responsible for the outbreak carries a very high number of genes known to be involved in disease. These include genes that influence the bacterium's ability to attach to surfaces and survival genes that increase tolerance to high acidity, low oxygen, UV light and antibiotics."

Novel method for increasing antibiotic yields
September 2011
A novel way of increasing the amounts of antibiotics produced by bacteria has been discovered that could markedly improve the yields of these important compounds in commercial production. It could also be valuable in helping to discover new compounds. With the ever-growing threat from antibiotic resistance, these tools will be very useful in ensuring that we have enough of these useful compounds in the future.

The majority of antibiotics we know of today are produced naturally by a group of soil bacteria called Streptomyces. In work carried out initially at the John Innes Centre, Professor Mervyn Bibb and collaborator Dr Koji Yanai from a Japanse laboratory discovered 36 repeating copies of one gene cluster in a strain of Streptomyces that had been repeatedly selected to over-produce the antibiotic kanamycin. Based on this observation Prof Bibb and colleagues have developed a system for the targeted amplification of gene clusters which they believe will work for many other Streptomyces strains and antibiotics, and may also uncover new, undiscovered antibiotics by amplifying cryptic gene clusters in other Streptomyces species.

Tuning natural antimicrobials to improve their effectiveness at battling superbugs
August 2011
Clostridium difficile is a common and dangerous source of hospital-acquired infections. At the moment, antibiotics are used to treat infections, but C. difficile is adept at acquiring resistance, meaning the number of effective antibiotics is ever decreasing. This has driven the search for new antimicrobials, and at IFR Melinda Mayer and Arjan Narbad have been focussing on bacteriophage endolysins. These are relatively short proteins produced by viruses that specifically target certain species of bacteria and then break open the cell walls. New research is showing that it is possible to 'tune' these endolysins to increase their effectiveness and aid their development as a new weapon in the battle against superbugs. Working with colleagues at the European Molecular Biology Laboratory (EMBL) in Hamburg, the structure of the catalytic domain of endolysin CD27L has been solved and used to design mutants to investigate what controls the specificity and activity of the endolysins.

Tung Le and Prof. Mark Buttner

JIC student brings home new expertise to answer question in antibiotic resistance
August 2011
John Innes Centre researchers, Tung Le working with Professor Mark Buttner (pictured, standing on right) and Dr David Lawson, have worked out the structure of a complex formed when a protein binds to DNA. This has proved to be key in understanding how an antibiotic-producing organism controls resistance to its own antibiotic, and may be an example of how other antibiotic producers regulate export to prevent self-toxicity.

"This provides a mechanism that couples the potentially lethal biosynthesis of the antibiotic to its export, which has wider implications for resistance to clinically important antibiotics," commented Prof. Buttner. "However, we needed to know more detail about the interaction between SimR and DNA."

Microbispora corallina

Antibiotic production controls unravelled to help in clinical development
July 2011
JIC scientists researching a new antibiotic have pieced together the way it is produced by a soil bacterium by working out the functions of its genes. Microbisporicin is produced by a soil bacterium from Indonesia called Microbispora corallina. A clearer understanding of how microbisporicin's synthesis is regulated by the bacterium will provide the basis for finding ways of optimising its production and so become a new weapon in the fight against multi-drug resistant pathogens.

Lantibiotics are a class of antibiotics produced by bacteria, and microbisporicin represents a potent example of the class, which has so far been under-exploited for clinical use. That could now change, as preclinical trials are showing that it is highly active against a large range of bacteria. To aid its pharmaceutical development, Professor Mervyn Bibb and Dr Lucy Foulston at the John Innes Centre, identified the genes that Microbispora corallina uses to regulate microbisporicin production.

Genome analysis will reveal how bacteria in our guts make themselves at home
June 2011
Dr. Lisa Crossman and other researchers from TGAC and IFR have published the genome sequence of a gut bacterium to help understand how these organisms evolved their symbiotic relationships with their hosts.

The IFR and TGAC researchers are now hoping to use this information to elucidate exactly what it is that restricts certain Lactobacillus reuteri strains to specific hosts.

L. reuteri confers certain health benefits, and has a role in modulating the immune system. A greater understanding of how L. reuteri host adaptation will help in efforts to exploit these health benefits, for example in the production of new probiotics.

A comparison between different E.coli strains

TGAC helps in crowd-sourcing analysis of E. coli strain
June 2011
Scientists from The Genome Analysis Centre (TGAC) have identified several genes which may be key factors in the recent E.coli outbreak of strain 0104:H4. The strain has now been implicated in a number of hospitalisations and deaths, particularly in Germany. The outbreak has also had a high economic impact on the fresh vegetable market, particularly in Spain and across the EU. The studies have been made possible by the public release of genome sequence data from BGI, China.

Dr. Lisa Crossman, TGAC Microbial Genomes Project Leader said "By studying the genetic factors involved in the survival of this bacterium on surfaces we hope to get an angle on how this organism has been able to get a foothold in the global food chain."

Discovery opens the door to electricity from microbes

Discovery opens the door to electricity from microbes
May 2011
Using bacteria to generate energy is a signifiant step closer following a breakthrough discovery by scientists at the University of East Anglia. The project is led by Dr Clarke, Prof David Richardson and Prof Julea Butt, in collaboration with colleagues at the Pacific Northwest National Laboratory in the US.

The discovery means scientists can now start developing ways to 'tether' bacteria directly to electrodes - creating efficient microbial fuel cells or 'bio-batteries'. The advance could also hasten the development of microbe-based agents that can clean up oil or uranium pollution, and fuel cells powered by human or animal waste.

Genome sequencing used to assess the threat to biosecurity from a novel form of Clostridium botulinum
March 2011
Professor Mike Peck and his research group at the Institute of Food Research (IFR) on the Norwich Research Park have sequenced the genome of a novel strain of Clostridium botulinum, one of the most dangerous pathogens known to man. The strain produces an unusual botulinum neurotoxin, known as type A5 neurotoxin, which was isolated by the Health Protection Agency (HPA), following a case of wound botulism.

"Our analysis of the genome sequence indicates that while the type of neurotoxin formed is unusual, the organism itself appears closely related to other strains of Clostridium botulinum, and is likely to pose a similar threat to food safety and biosecurity" said Professor Peck.

Dr Jun Fan

What is good for you is bad for infectious bacteria
March 2011
Plants are able to protect themselves from most bacteria, but some bacteria are able to breach their defences. In research to be published in Science (Science 4 March 2011: Vol. 331 pp. 1185-1188 ), scientists have identified the genes used by some strains of the bacterium Pseudomonas to overwhelm defensive natural products produced by plants of the mustard family, or crucifers.

"Microbes only become pathogens when they find a way to infect a host and overwhelm the host defences," said lead author Dr Jun Fan from the John Innes Centre on the Norwich Research Park.

"Our findings answer some important questions about host-pathogen biology."

Streptomyces Coelicolor

Engineered bacterium is helping in the search for new antibiotics
March 2011
To help in the search for new antibiotics JIC scientists, Juan Pablo Gomez-Escribano and Professor Mervyn Bibb, have adapted a strain of Streptomyces coelicolor to express clusters of genes found from genome sequencing projects whose functions are unknown.

The strains are now being used by a number of different research groups. "We believe that these strains can make a major contribution to the discovery of novel natural products and may contribute significantly to addressing the urgent need for new antibiotics," said Prof Bibb.

aphids

Key to aphid invasion success found
February 2011
Aphids are some of the most destructive insect pests of crop plants, not only through the damage they cause from feeding but also through transmitting a variety of economically important diseases. Part of what makes them so effective is the way they can control some of the activities of plants, suppressing their defences and so helping the aphids feed. New research by Dr Jorunn Bos, working with Dr Saskia Hogenhout from the John Innes Centre, has shown that just as plant pathogens produce effector proteins that manipulate the plant's defences, aphids can also produce effector proteins in their saliva that affect plant defense responses and/or aphid reproductive performance.

Powdery mildew on wheat

Norwich gene hunters tackle crop diseases
December 2010
Norwich scientists are on the trail of some of the most economically damaging organisms that infect crops worldwide. Published in the same edition of the journal Science are a series of studies of plant pathogen genomes. One study, led by Professor Sophien Kamoun, examined how the genome of the pathogen that causes potato late blight evolves as it jumps from one host plant to another. "It is important to understand how the pathogen adapts to its plant hosts. In this latest study we have learnt more about how the pathogen evolves to attack new hosts." said Professor Kamoun.

Two further studies focus on the parasites that cause downy mildew (an oomycete disease of many crops including maize, grapes and lettuce) and powdery mildew (a fungal disease of barley). The genomes have been sequenced in separate research collaborations, one involving John Innes Centre scientists and the other The Sainsbury Laboratory. Analysis revealed that the parasites have become specialised to live solely on their plant host and have dispensed with the genes that would be needed to survive elsewhere. Instead they have focussed on genes that help them stealthily take control of host cells. The genome sequences reveal large numbers of effector proteins, the molecules that invade plant cells to suppress plant immunity.

'Missing' bacteria in Irritable Bowel Syndrome and Ulcerative Colitis patients identified
November 2010
Scientists have identified some bacteria that are low in abundance in the gut of Irritable Bowel Syndrome (IBS) and ulcerative colitis (UC) patients compared to healthy adults. This finding could be relevant to preventing or managing these conditions to maintain health.

"A better understanding of which bacteria or bacterial populations are relevant to ulcerative colitis and IBS is important if microbial interventions are to be used in preventing or managing these conditions," said Dr Arjan Narbad from the Institute of Food Research.

The work was published in the journal BMC Gastroenterology and was funded through IFR's strategic programme grant from the BBSRC and by the Ministry of Higher Education of Saudi Arabia in the form of a PhD studentship to Samah Noor.

Botulinum

IFR develops new method for detecting Clostridium botulinum spores
October 2010
IFR has collaborated in the development of a new method for detecting spores of non-proteolytic Clostridium botulinum. This bacterium is the major health hazard associated with refrigerated convenience foods, and these developments give the food industry and regulators more quantitative information on which to base the procedures that ensure food safety.

Professor Mike Peck, Acting Programme Leader (Bacterial Foodborne Pathogens) at IFR, says the economic and social costs associated with foodborne botulism are immense. "The fatality rate is in the region of 10% of cases, while full recovery may take months or even years. It is estimated that the economic cost per case associated with commercial food is $30M in the US." He adds that stringent precautions taken by industry ensure that foodborne botulism is rare in the UK.

Ants tending their fungus garden

Ants found to use multiple antibiotics as weed killers
August 2010
Scientists at the University of East Anglia, have shown that fungus-farming ants are using multiple antibiotics as weed killers to maintain their fungus gardens.

Research led by Dr Matt Hutchings and published today in the journal BMC Biology shows that ants use the antibiotics to inhibit the growth of unwanted fungi and bacteria in their fungus cultures which they use to feed their larvae and queen.

Dr Hutchings said: "We found a new antifungal compound that is related to a clinically important antifungal named nystatin so we’re excited about the potential of these ants and other insects to provide us with new antibiotics for medical use."

Cheese

IFR researchers have demonstrated a potential new way of preventing spoilage in cheese
August 2010
Late-blowing in cheese production is a significant problem, causing spoilage and losses that contribute to wastage and decrease efficiency. Funded by the BBSRC, researchers at IFR have identified and characterised a naturally occurring microorganism that specifically attacks C. tyrobutyricum, the organism behind late-blowing.

In research published in the journal Applied and Environmental Microbiology, Melinda Mayer, Arjan Narbad and colleagues demonstrate the potential use of this bacteriophage for controlling C. tyrobutyricum. The bacteriophage produces a protein, called an endolysin, which recognises C. tyrobutyricum and breaks open its cells. The group sequenced the genome of the bacteriophage and identified the gene encoding the endolysin. Cloning this gene into E. coli allowed them to produce the endolysin protein to assess its ability to control C. tyrobutyricum levels.

Key milestone towards the development of a new clinically useful antibiotic
July 2010
Scientists from the John Innes Centre have identified the genes necessary for making a highly potent and clinically unexploited antibiotic in the fight against multi-resistant pathogens.

"Lantibiotics are antibiotic molecules produced by soil bacteria, and we are studying probably the most potent one known, microbisporicin, which is active against many different pathogens," said Professor Mervyn Bibb from the John Innes Centre, co-author on the paper to be published in PNAS.

The producing bacterium, Microbispora corallina, is difficult to work with. It grows very slowly and no tools existed for its genetic manipulation. PhD student Lucy Foulston developed the tools herself. She then took advantage of new developments in genome sequencing to identify and then isolate the M. corallina gene cluster responsible for microbisporicin production.

Lifeline for antibiotic of last resort
July 2010
An international team of scientists has uncovered how bacteria sense vancomycin, a mechanism that triggers resistance to this powerful antibiotic.

"Vancomycin resistance is thankfully still rare in MRSA, but if it became more widespread we could risk edging backwards to the pre-antibiotic era," says Professor Mark Buttner from the John Innes Centre, an institute of BBSRC. "We need to have a back-up ready in case resistance becomes more common."

Spitting out detergents and chewing up pollutants
July 2010
A team of scientists from UEA and Dundee have discovered a novel way in which Streptomyces bacteria export and display proteins on their cell surface. Led by Dr Matt Hutchings (UEA) in collaboration with Professor Tracy Palmer (Dundee) the team have exploited this natural pathway to develop strains of Streptomyces and Bacillus bacteria that can secrete or cell surface display proteins that could be useful for industry or medicine. This technology has been patented by UEA and licensed exclusively to PBL.

The research is described in a paper published in the journal Molecular Microbiology (doi 10.1111/j.1365-2958.2010.07261.x). The team anticipate that this technology will be widely applicable for industrial and biomedical use, for example to produce enzymes for biological washing powders or antibodies for therapeutic use. The work was funded by research grants from the BBSRC and technology development grants from the BBSRC and UEA.

Sainsbury Laboratory

GM Trial to reduce agrochemicals
June 2010
A field trial of GM potatoes is being planted this week to test whether genes from wild relatives can successfully protect commercial potato varieties from late blight – the disease that caused the Irish potato famine – without the need to spray fungicides.

At the moment British farmers spray on average 15 times a year to protect against potato late blight.

"We have isolated genes from two different wild potato species that confer blight resistance," said Professor Jonathan Jones from the Sainsbury Laboratory on Norwich Research Park. "Similar genes are found in all plants, and we are now testing whether these ones work in a field environment to protect a commercial potato variety, Desiree, against this destructive potato disease."

campylobacter jejuni

Biofilm production aids campylobacter survival
March 2010
Scientists at the Institute of Food Research have found a way that the foodborne pathogen Campylobacter can survive in the environment. Campylobacter is the main cause of food poisoning in Europe and America.

Campylobacter cannot survive in the oxygen levels in the air, which forces the bacterium to adapt for survival in the food chain. One such a survival strategy is to form a biofilm, whereby the bacteria stick to a surface and encase themselves in a sticky 'slime' which protects them.

"While biofilms are well established in the lifestyle and success of other pathogenic bacteria, their role in the lifestyle of Campylobacter was still unclear. We now have developed a model where the biofilm plays a central role in the transmission of Campylobacter via the food chain, and this may lead to new antimicrobial approaches, like disrupting the biofilm matrix or prevention of biofilm formation." commented Dr. Arnoud van Vliet.

Mycobacterium tuberculosis

Scientists make TB bug suicidal
March 2010
Dr Steph Bornemann and scientists from the Albert Einstein College of Medicine of Yeshiva University (Einstein), in New York, have identified a new class of drug target that tricks tuberculosis bacteria into suicidal self-poisoning. Researchers identified the role that an enzyme called GlgE plays in Mycobacterium tuberculosis, the cause of tuberculosis and the leading cause of death worldwide from bacterial pathogens. It claims about two million lives every year.

"With the advent of antibiotics, TB became treatable and at one point eradication was believed possible," says Dr Steph Bornemann from the John Innes Centre.

"But TB has re-emerged as a major global health threat due to poverty, a deadly synergy with HIV and the emergence of drug resistant strains that are virtually untreatable with current therapies."

Together the scientists have identified a four-step metabolic pathway involving GlgE that represents a new target for anti-tuberculosis drugs.

tomato plants infected with Ralstonia solanacearum

New defences deployed against plant diseases
March 2010
An international team led by scientists at the Sainsbury Laboratory in Norwich have transferred broad spectrum resistance against some important plant diseases across different plant families. This breakthrough provides a new way to produce crops with sustainable resistance to economically important diseases.

Plants have a defence system, based on pattern recognition receptors (PRRs). PRRs recognise molecules that are essential for pathogen survival. These molecules are less likely to mutate without harming the pathogen’s survival, making resistance to them more durable in the field. However, very few of these PRRs have been identified to date. Dr Cyril Zipfel and his group at the Sainsbury Laboratory in Norwich, UK, took a Brassica-specific PRR that recognises bacteria, and transformed it into the Solanaceae plants Nicotania benthaminia and tomato. These plants then showed drastically enhanced resistance against many different bacteria indicating that this approach provides a new biotechnological solution to engineering disease resistance in plants.

Dr Michael McArthur

JIC scientist wins prestigious national award
March 2010
Dr Michael McArthur has been named the winner of 'Most Promising Innovator of the Year' award for his work using novel antibacterials to combat drug-resistant bacterial infections. Dr McArthur has developed novel technologies to combat drug resistant bacterial infections, such as MRSA and a spin-out company from the John Innes Centre, Procarta Biosystems, is now taking this technology through to the marketplace.

"Over the last decade all the major pharmaceutical companies have been bringing fewer antibiotics to the market, some have even departed the field altogether, a trend that is likely to be exacerbated by resistance issues. Procarta's novel solution not only tackles antibiotic resistance but also is a solution which should be far less susceptible to resistance" said Michael.

Sarum Biosciences

Clostridium difficile bacteriophage endolysin technology
January 2010
Sarum Biosciences Limited ("Sarum") and PBL, the UK technology management company, announced on 22nd February the signing of an exclusive worldwide licence agreement which enables Sarum to develop and exploit therapeutic and diagnostic applications of a bacteriophage endolysin protein for the treatment and detection of Clostridium difficile, a serious healthcare concern both within the UK and the rest of the world.

"Using bacterial endolysins has been of interest to IFR for many years in the food context," said Dr Arjan Narbad of the IFR, an institute of the BBSRC, which funded the study. "Now we have an endolysin that is active specifically against C. difficile we are looking forward to developing it into a potent weapon against this problem."

Rock-breathing bacteria could generate electricity and clean up oil spills
December 2009
A discovery by scientists at the University of East Anglia could contribute to the development of systems that use domestic or agricultural waste to generate clean electricity.

The findings could be applied to help in the development of new microbe-based technologies such as fuel cells, or 'bio-batteries', powered by animal or human waste, and agents to clean up areas polluted by oil or uranium.

"This is an exciting advance in our understanding of bacterial processes in the Earth’s sub-surfaces," said Prof David Richardson, of UEA's School of Biological Sciences, who is leading the project.

A sticky solution for identifying effective probiotics
November 2009
Scientists at the IFR and UEA have crystallised a protein that may help gut bacteria bind to the gastrointestinal tract. The protein could be used by probiotic producers to identify strains that are likely to be of real benefit to people.

"Probiotics need to interact with cells lining the gut to have a beneficial effect, and if they attach to surfaces in the gut they are more likely to stick around long enough to exert their activity," says Dr Nathalie Juge from the Institute of Food Research.

Mucus adhesion has been well studied for pathogenic bacteria, but precisely what enables commensal (our gut bacteria) bacteria to stick is not known. In a paper published in the Journal of Biological Chemistry, IFR and UEA scientists have obtained the first crystal structure of a mucus-binding protein.

Institutes provide valuable experience for students
July 2009
Schoolchildren from across Norfolk have been gaining valuable work experience at the Norwich BioScience Institutes, giving them an idea of what it is like to work in at a leading science campus. The 14 and 15 year-olds have been working in a variety of different laboratory environments, looking at things such as analysing genome sequences, extracting DNA from bacteria, and crystallising proteins.

Emma Sherwood, a post-graduate student working in Prof. Mervyn Bibb's group in the Molecular Microbiology Department at the John Innes Centre, said "I wanted to host a student because I know that I would have liked the opportunity to do work experience in a science lab when I was at school".

Sarah Tolland, assistant to Prof. Tony Maxwell, together with Dave Hart at the IFR, coordinated the work experience scheme. "We have been delighted with the positive response to the scheme. We are keen to encourage students to study science, but we understand that it can be difficult to see how what you learn in science lessons can be translated into a career." Sarah said.

New national genome centre opens in Norwich
July 2009
The Genome Analysis Centre (TGAC - http://www.tgac.bbsrc.ac.uk/), a new national genome centre, was officially opened on the Norwich Research Park on 3 July. Dr Jane Rogers, Director of TGAC, said: "The Genome Analysis Centre will give the UK a lead in the sequencing of the genomes of plants, animals and microbes. The genomic analysis of microbes will be a major focus, not only because they infect both animals and plants, but because some are already a source of drugs for the treatment of bacterial and fungal infections and therefore they have the potential to provide new, superbug beating antibiotics."

Rhythmic genomics – the yeast metronome and the walk of life
April 2009
New genome sequence information from the humble baker’s yeast has revealed surprising variation in a set of genes that can be thought of as nature’s oldest clock. In a paper published in Genome Research scientists show how ribosomal RNA genes that are essential to all Earth's organisms provide insight into how genomes maintain their integrity on their evolutionary journey. Because even the slightest changes in sequence of these genes could be fatal.

Rob Davey, computational biologist at the National Collection of Yeast Cultures (NCYC), said "we can use new computer techniques to model the changes mathematically and really get to grips with what orchestrates the variation in these important cell housekeepers."

Ian Roberts, Curator of NCYC, said "Yeasts are everywhere around us in nature and industry. This extra level of detail allows us to resolve important differences between yeasts and gain maximum benefits from their use in food, drink and healthcare."

In Dublin he will continue this work, with a particular focus on Salmonella.

National Science and Engineering Week

National Science and Engineering Week at the Norwich BioScience Institutes
March 2009
March 6th sees the start of The British Science Association’s National Science and Engineering Week, and as part of this the John Innes Centre and the Institute of Food Research are hosting an interactive exhibition at The Forum in Norwich celebrating the birth of Charles Darwin and the 150th anniversary of the publication of his most famous work, On the Origin of Species. They will also be showcasing the work of their young scientists, giving the chance to hear about the latest work on topics such as antibiotics and how our gut protects us from invasion.

At the Showcase of Young Science on March 11th, students and their supervisors will describe their work to groups from Norwich schools as well as to a public audience. From the Molecular Microbiology department at the John Innes Centre, Jan Claesen, with Prof. Mervyn Bibb, is investigating cypemycin, a new, unusually modified antibiotic. By understanding how cypemycin is made they may be able to produce better derivatives, which will be crucial to countering the threat of antibiotic resistance.

Science, Art and Writing
February 2009
Science, Art and Writing (SAW) is a UK-based science education initiative that breaks down traditional barriers between science and the arts. SAW uses themes and images from science as a starting point for scientific experimentation, art and creative writing and in doing so stimulates creativity and scientific curiosity. The stunning science images and the artworks inspired by them have been collected together in ‘SAW Showcase’, published by the SAW Trust on February 28th.

In 2008 Professor Anne Osbourn led a series of projects aimed at taking research science from the Norwich Research Park-based John Innes Centre and the Institute of Food Research into Norfolk schools using SAW as a vehicle. The John Innes Centre and the Institute of Food Research are Institutes of the Biotechnology and Biological Sciences Research Council, who, along with the science outreach organisation Society in Science, provided funding for this set of SAW projects.

On the Origin of Subspecies
February 2009
Scientists have sequenced over seventy strains of yeast, the greatest number of genomes for any species. The analysis, to be published in Nature, enables the scientists to study genetics in much finer detail than was ever possible for Darwin. They are able to see the differences within a species and use this knowledge in understanding yeast biodiversity and exploiting it for human benefit. "We can sift through billions of DNA bases to clearly spot a wild yeast or the mosaic genome of a recent hybrid," says Dr Ian Roberts, leader of the NCYC research team and the collection’s curator.

The basic machinery of yeast is surprisingly similar to that of humans, and the project is already helping experts to develop the tools necessary for studying human genetic variation. Yeast can also be used to develop and test new drugs, such as for cancer. "This is a valuable test bed for the 1000 genomes project, in which the genomes of 1000 people are being sequenced," said Professor Ed Louis from the University of Nottingham.

ONE SYSTEM - two different relationships
January 2009
A JIC combination of biological and mathematical approaches has provided a novel explanation for the mechanisms of multi- functionality in signalling pathways.

Plants have symbiotic relationships with micro-organisms, which benefit both partners. Leguminous plants, such as peas and beans, form nodules on their roots which house rhizobia, bacteria which are able to "fix" nitrogen. However, arbuscular mycorrhizal fungi are very different to rhizobia, and produce very different reactions in the plants. Although both symbiotic relationships activate and use several of the same plant genes, it is only now that a JIC team, led by Giles Oldroyd and Allan Downie, have discovered how the one system can manage two different relationships.

Scholarship award for IFR student
December 2008
PhD student Richard Bailey from the Institute of Food Research in Norwich has received an award from the British Poultry Council for his work on understanding dysbacteriosis, a disease of growing importance in the poultry industry.

Dysbacteriosis is a poorly understood condition that causes enteritis in broiler chickens. It is thought to be due to an overgrowth of the gut microflora. Richard’s work within a group led by Dr Arjan Narbad has focussed on identifying which micro-organinsms may be responsible for the condition.

Actinomycetes

Dr Matt Hutchings and Co-Applicants gain MRC Milstein Award
December 2008
Dr Matt Hutchings, together with co-applicants Doug Yu (BIO) and Rebecca Goss (CAP), has been successful in gaining an MRC Milstein award to study novel anti-fungal compounds. The Milstein fund was set up in 2006 to support pioneering research from UK based scientists who can demonstrate highly innovative ideas and approaches to contemporary challenges in medical research. The initiative is named after César Milstein who was honoured with a Nobel Prize in 1984 for his pioneering work on the production of monoclonal antibodies.

Dr. Hutchings’ project focuses on novel anti-fungal compounds produced by actinomycete bacteria living as symbionts on Amazonian leaf-cutter ants. The ants farm fungi which they grow on harvested leaves as the sole food source for the ant colony. They mix the fungi and the bacteria and inoculate them onto the leaves where the bacteria produce antibiotics to inhibit the growth of other fungi. This allows the ants to grow pure cultures of the fungus they like to eat. These ants are therefore potential novel sources of anti-fungals which could be used in human medicine but to date none of these compounds has been isolated or identified.

Bacterial Lysis by Anndolysinhas

Viruses Offer Hope for New Weapon Against C. difficile Infection
September 2008
Clostridium difficile-associated disease, or CDAD forms a major part of the spectrum of serious hospital-acquired infections, and is much in the news at present. Last year there were approximately 500,000 cases in the US alone, and globally an increasing proportion of infections are by a new virulent type of C.diff that can cause death in up to 30% of patients. Although most strains of C.diff are currently sensitive to antibiotics, there are high relapse rates (up to 25%). Antibiotics have the disadvantage of damaging the normal gut bacteria, which predisposes the patient to the condition in the first place. There is therefore a pressing need for improved therapies to combat this problem.

Now a group from the Institute of Food Research, led by Prof Mike Gasson, has isolated a lysogenic (inactive) bacteriophage from C.diff and shown that its endolysin gene can be used to make an active protein that is capable of killing C.diff. The work has been submitted as a patent application by PBL, and Prof Gasson is working with PBL to develop the opportunity further.

Reducing Food Poisoning by Clostridium
August 2008
Clostridium perfringens type A is a significant cause of food poisoning. Spores are commonly found in meat and poultry, albeit at a low concentration, and this pathogen is a particular problem when cooked foods are subject to inadequate cooling. The main concern is bulk meats cooked in large batches. A dynamic predictive model has been developed by IFR scientists József Baranyi and Mike Peck to describe the effects of temperature, pH and NaCl concentration on the growth of Clostridium perfringens type A. This new dynamic predictive model has been implemented in the IFR-developed Perfringens Predictor, a web-based application that can be accessed free of charge via www.combase.cc. These studies will contribute to a reduction in the food poisoning incidence associated with C. perfringens.

Clostridium botulinum

Publication of Clostridium botulinum genome explains its toxicity
May 2007
Scientists including Professor Mike Peck from the Institute of Food Research have published the Clostridium botulinum genome in Genome Research. Their findings show that C. botulinum does not have genes to help it evade its hosts' immune systems, rather it simply kills the host and feeds off the remains before biding its time as a spore before another host presents itself. This is in contrast to other Clostridium species that do employ stealth tactics when invading their hosts. Other findings are that the C. botulinum varieties should perhaps be defined as separate species, that they can also feed of soil insects and crustaceans and that the C. botulinum’s genome holds almost no genes acquired from other species whereas C. difficile has over 10% acquired genes. These findings show how diverse the Clostridia are.
