NewsCrop-killing pathogen found to disable plant ‘alarm system’
An international team has discovered that the pathogen Phytophthora infestans - which caused the Irish potato famine - employs special enzymes, called AA7 oxidases, to disable the plants’ early warning system, weakening their defenses before they can respond.

NewsGlobal analysis reveals how biochar supercharges composting and cuts greenhouse gases
By analyzing data from 125 studies across the world, researchers showed that adding biochar to composting systems significantly boosts compost quality while slashing harmful greenhouse gas emissions.

NewsFertilizer boosts soil’s ability to lock away carbon
The 180-year experiment at Rothamsted — the world’s longest-running agricultural trial — has revealed that long-term application of nitrogen and phosphorus fertilisers can significantly increase the amount of carbon stored in farmland soils, helping to mitigate climate change.

NewsRoot chemistry determines how antibiotic resistance spreads from manure to crops
Researchers found that the rhizosphere, the narrow soil zone surrounding plant roots, is a major hotspot for the accumulation of manure-derived ARGs. Across eight common crops, ARG abundance in rhizosphere soil was on average 1.24 times higher than in bulk soil.
-
NewsResearchers uncover hidden plant–microbe strategy that boosts crop growth under nutrient stress
Scientists discovered that when soil microbes compete with each other in the rhizosphere, they release a well-known compound called glutathione. This compound enhances plant growth under sulphur-deficient conditions.

NewsBiochar and plants join forces to clean up polluted soils and boost ecosystem recovery
A review explores how combining biochar with rhizoremediation, a nature-based process that uses plant roots and beneficial microbes to break down pollutants, can greatly enhance soil restoration. Biochar acts as both a catalyst and a habitat for microbes.

NewsSlime mold metabolites are a promising, eco-friendly repellent of root-knot nematodes
A team of researchers has discovered 14 compounds secreted by slime molds that repel root-knot nematodes (RKNs) - worm-like parasites of the genus Meloidogyne - and could be the source of new, non-toxic anti-RKN pesticides.

NewsDeadwood-decomposing fungi feed germinating orchids
Deadwood-decomposing fungi feed germinating orchids, providing the carbon their tiny seeds don’t have. The finding not only closes a gap in our understanding of wild orchid ecology but also uncovers an important carbon flux in the ecosystem.

NewsSoil bacteria and minerals form a natural ‘battery’ that breaks down antibiotics in the dark
Researchers have unveiled a surprising new way that soil microbes can use sunlight energy. The team developed a “bio-photovoltage soil-microbe battery” that can capture, store, and release solar energy to power the breakdown of antibiotic pollutants in the dark.

NewsCould slime mold microbes be a source of potent antimicrobials?
The cellular slime mold Dictyostelium discoideum is a soil microbe that produces diverse natural products with potential antibiotic activity. In this study, researchers optimized lab culture conditions of Dictyostelium cells to boost the levels of low-abundance chlorinated compounds and to characterize their antimicrobial properties.

NewsBiodegradable microplastics rewire carbon storage in farm fields
A pioneering two-year field study has revealed that biodegradable microplastics, often hailed as eco-friendly alternatives to conventional plastics, are quietly reshaping the chemistry of farmland soils in unexpected and complex ways. They attracted a special group of microbes known as K-strategists—slow-growing, efficient decomposers.

NewsGolden spruce trees: Gold forms nanoparticles in the needles – bacteria show the way
A new study has, for the first time, uncovered a connection between bacteria living in Norway spruce needles and gold nanoparticles. This discovery could pave the way for environmentally friendly gold exploration methods, while examining similar processes in mosses may also help remove metals from mining-impacted waters.
