NewsAncient symbiosis between plants and fungi: Important insights for sustainable agriculture
Almost all plants live in close symbiosis with so-called mycorrhizal fungi – an important symbiosis for absorbing essential nutrients. Scientists have discovered that this mycorrhizal symbiosis is very sensitive to imbalances of certain nutrients in the soil.

NewsPeriphyton closes the nitrogen budget gap in rice paddies
Scientists identify a previously overlooked microbial N sink in rice paddies. Periphyton, a thin microbial community that develops at the soil–water interface, is composed of algae, bacteria, and extracellular polymeric substances, forming a dense microhabitat with strong capacities for nutrient uptake, transformation, and temporary storage.

NewsEpigenetic rewiring fuels potato susceptibility to late blight
Scientists performed whole-genome bisulfite sequencing and RNA sequencing on the widely cultivated potato cultivar Qingshu No.9 following Phytophthora infestans infection, uncovering dynamic DNA methylation shifts that correlate with large-scale transcriptional reprogramming and immune suppression.

NewsMicrobes unlock a hidden natural source of mercury emissions from ‘stable’ minerals
A new study reports a previously overlooked natural mechanism that could contribute substantially to global mercury emissions. Researchers show that chemolithoautotrophic microbes can use mercury sulfide nanominerals as an energy source and, in the process, release volatile Hg0 into the air.

NewsWater bears reveal potential for adapting and protecting Martian resources
Microscopic tardigrades help inform how simulated Martian soil might support plant life and mitigate contaminants shedding from human explorers, researchers report.

NewsNative forest litter helps rebuild soil life in post-mining landscapes
Researchers investigating rehabilitated land near a former uranium mine in northern Australia found that introducing leaf litter from nearby native Eucalyptus woodlands rapidly reshaped soil microbial communities and improved their functional potential.

NewsMountain soils in arid regions may emit more greenhouse gas as climate shifts, new study finds
A new field study from northwestern China reveals that climate-driven changes in temperature and moisture could significantly reshape nitrous oxide emissions from soils in arid mountain ecosystems, with important implications for future climate feedbacks.

NewsSource or sink? Trees with heart rot disease emit more methane, upending forest carbon models
New research suggests that upland forests harboring trees with a common and incurable fungal disease known as heart rot could actually be emitting more methane than they take in, therefore releasing more greenhouse gases than previously thought.

News How recycled sewage could make the moon or Mars suitable for growing crops
Scientists are investigating how a solution of recycled sewage interacts with simulated lunar and Martian regolith to see if the result provides a suitable medium to grow crops. Bioregenerative life support systems consist of a series of bioreactors and filters that transform sewage into a nutrient-dense solution.

NewsScientists uncover how engineered biochar and microbes work together to boost plant-based cleanup of cadmium-polluted soils
A new study reveals how specially modified biochar can significantly improve the ability of willow trees to remove toxic cadmium from contaminated soils, offering a promising strategy for restoring polluted land in a sustainable way.

NewsApplied Microbiology International launches new report on improving soil health in the UK
Scientists have warned that the world’s tiniest organisms need to be taken into account in efforts to improve soil health. AMI has launched a new policy report setting out key recommendations to support the long-term protection, restoration and sustainable management of soils across the UK’s four nations.

NewsNovel structural insights into Phytophthora effectors challenge long-held assumptions in plant pathology
How do evolutionarily conserved pathogen effectors maintain structural stability while engaging diverse host targets? In a new study, researchers define a conserved subset of Phytophthora RxLR effectors in which short linear motifs (SLiMs) are embedded within folded WY domain cores.

NewsHow citrus rewires its vascular system to fight Huanglongbing
By profiling thousands of individual cells, researchers mapped how different vascular cell types in citrus roots respond during early stages of infection with Candidatus Liberibacter asiaticus, revealing profound changes in cell fate, gene expression, and tissue differentiation.

NewsA single gene, a dramatic change: CRISPR unlocks white strawberries
Researchers used CRISPR/Cas9 to selectively edit a single dominant gene copy controlling fruit color in the commercial octoploid strawberry cultivar ‘Florida Brilliance’. By targeting the MYB10-1B gene, they successfully converted red strawberries into stable white-fruited plants.

NewsResearch teams will develop automated compost monitoring system
Composting turns organic waste into nutrient-rich material, but improper temperature and moisture control can allow pathogens to survive and increase safety risks. Researchers have received a $362,000 grant to develop an automated sensor network to improve monitoring of compost piles.

NewsMicroplastics in soil may reshape microbial genes and threaten ecosystem stability
A new review highlights how microscopic plastic particles accumulating in soils can alter microbial genes that control essential ecosystem functions, potentially affecting food production, climate processes, and environmental health.

NewsPeatland lakes in the Congo Basin release carbon that is thousands of years old
Researchers have discovered that large blackwater lakes in the extensive peatlands of the central Congo Basin are releasing ancient carbon. How the carbon is mobilised from the peat to the lake, where it is finally released to the atmosphere, is still unknown.

NewsHope for global banana farming in genetic discovery
Scientists have pinpointed crucial genetic resistance to fight a fungal disease which threatens the global banana supply in a wild subspecies of the fruit. The team have identified the genomic region that controls resistance to Fusarium wilt Sub Tropical Race 4 (STR4).

NewsAncestral motif enables broad DNA binding by NIN, a master regulator of rhizobial symbiosis
Researchers investigated the molecular mechanisms whereby the transcription factor NODULE INCEPTION (NIN) - crucial for rhizobial symbiosis - can bind a broader spectrum of DNA sequences than its close homologs, using the legume Lotus japonicus (Miyakogusa) as a model system.

NewsLower tillage boosts the soil’s natural phosphorus cycle - cutting the need for costly fertilizer inputs
Long-term tillage reduction helps to restore the soil’s natural phosphorus cycle, supporting more sustainable nutrient management with less reliance on costly and finite fertilizer inputs, according to a new study published in Sustainable Microbiology.
