Food security
Millions of people are undernourished globally and with the population growing, food security is a major concern. Food security is multifaceted, requiring advancements in food safety, ensuring products have a good shelf life, reducing spoilage and providing dietary additions to improve the nutrient intake of the population. The application of microbiology is far reaching, and new approaches are required to maintain food security. Through an improved understanding of plant-microbe interactions, it is possible to forecast and mitigate food shortages.

NewsStaphylococcus aureus is highly resistant and virulent in milk
Staphylococcus aureus is frequently found in human and veterinary infections. Its ability to withstand antibiotic treatment makes it a major clinical challenge. To better understand the factors underlying this resistance, the scientists investigated the growth of the bacterium in two environments relevant to infection: milk and serum.
NewsStudent earns competitive fellowship for research on corn’s defense against bacteria
New funding has been awarded for research focused on understanding how plants protect themselves against pathogens. Peyton Sorensen looks specifically at corn and two of its bacterial pathogens: Xanthomonas and Clavibacter, which cause bacterial leaf streak and Goss’s bacterial wilt and blight, respectively.
NewsWeather and poultry litter shape E. coli survival in onion fields
How long can E.coli survive in the soil beneath an onion crop? A two-year field study suggests the answer depends not only on the type of poultry-based fertiliser used, but also on weather conditions such as humidity, rain, temperature and wind. The findings could help growers and regulators better assess food safety risks as extreme weather becomes more common.

NewsAFYREN and Terrial renew their partnership for French-manufactured potash fertilizers
AFYREN and Terrial today announce the renewal of their strategic partnership with the signing of a new multi-year fertilizer supply contract, worth several tens of millions of euros This long-term contract strengthens both companies’ commitment to making French agriculture more sustainable and less dependent on international fertilizer markets.
NewsThe Andes were supposed to stop this cacao killer - they didn’t
Black pod disease destroys up to a quarter of the world’s cacao every year. A study provides the first comprehensive portrait of Phytophthora palmivora’s genetic structure in Colombia. Researchers genotyped and virulence-tested 73 isolates gathered from 48 locations across the country’s three main cacao-growing regions.
NewsRoot gene panel reveals hidden apple replant disease
In-depth research is needed to identify biomarkers that can diagnose apple replant disease (ARD) consistently across diverse soils. Researchers measured the expression of 90 candidate genes in the roots of ARD-sensitive ‘M.26’ apple plants grown in soils from 151 German sites.
NewsHow straw is returned to soil can make a major difference in nitrous oxide emissions
Returning crop straw to farmland is widely used to recycle nutrients and improve soil quality. But new research shows that the way straw is returned to soil can strongly influence how effectively it limits emissions of nitrous oxide, a potent greenhouse gas.
NewsFAO renews university’s designation as Reference Centre on Antimicrobial Resistance and Aquaculture Biosecurity
The Food and Agriculture Organization of the United Nations is redesignating Mississippi State University as an FAO Reference Centre on Antimicrobial Resistance and Aquaculture Biosecurity.
NewsNew dynamic vision of the rhizosphere moves beyond the drive to just add more inputs
A new Perspective argues the case for an expanded view of the rhizosphere as a dynamic system, paving the way for a vision of sustainable soil management that moves beyond simply adding more fertilizers, microbial products, or other inputs.
NewsKibble with microbial proteins appeals to cats and dogs in new study
In a new study, cats and dogs showed a short-term preference for kibble containing some protein derived from microorganisms over kibble containing only standard, animal-derived protein.
NewsCan this biotech innovation halt the destructive march of a cereal killer?
Researchers explored a recently discovered class of plant defence receptors, showing at molecular level how they function to limit blast pathogen attacks and how they might be bioengineered to introduce broader more durable immunity into wheat, barley, and rice.
NewsScientists demonstrate mushroom fermentation method to enhance protein content and flavour of soybean by-product
The lab-scale study highlights the potential of solid-state fermentation to upcycle perishable okara into a nutritious food ingredient.
NewsYour gut makes a molecule that fights a leading cause of food poisoning
Researchers have discovered that a molecule called indole can inhibit the growth of Campylobacter jejuni, a leading cause of food poisoning worldwide. Their study builds on years of research aimed at understanding how C. jejuni manages to thrive in the gut and cause disease.
NewsHow a pathogen turns flowers into leaves
Scientists have found how a protein produced by bacteria disrupts the mechanism that controls flower development in plants, turning reproductive organs into leaf-like structures. These findings shed light on a plant disease that is expected to spread as climate change expands the range of its insect vectors in northern latitudes.
NewsKey regulator helps seafood-associated bacterium balance iron and oxidative stress
Bacteria need iron, but bioavailable iron is often scarce, and too much can fuel chemical reactions that damage cells. Many Gram-negative bacteria balance iron through ferric uptake regulator (Fur), a metal-responsive protein that controls iron-related genes. Fur’s role in V. parahaemolyticus, however, had not been clearly defined.
NewsBreakthrough optimization of chlamydospore fermentation for Cladophialophora guangxiense HX2
The dark septate endophyte Cladophialophora guangxiense HX2 exhibits excellent control efficacy against tomato bacterial wilt but industrial production of its chlamydospores has been challenging. Researchers have optimized the liquid fermentation process using chlamydospore yield of strain HX2 as the key response indicator.
NewsShapeshifting plant roots rely on a balance of anatomy, metabolism, and microbes to maximize survival
Scientists have identified the mechanisms that allow plants to change their root anatomy to maximise survival when nutrients are scarce. The findings could pave the way for developing new ways to improve beneficial plant-microbe interactions in agriculture.
