NewsModified biochar helps compost retain nitrogen and build richer soil organic matter
A new study reports that specially engineered biochar can significantly improve compost quality by reducing nitrogen loss and accelerating the formation of stable humic substances. The findings offer a promising strategy for transforming organic waste into more effective fertilizers while lowering environmental emissions. Composting plays a critical ...

NewsBiodegradable mulch isn’t disappearing as expected, new study warns
Scientists investigated how soybean roots influence the degradation of PBAT microplastics in soil. They tracked both polymer loss and monomer accumulation over a full 70-day plant growth cycle, revealing size-dependent and condition-specific rhizosphere effects.

NewsEditing for timing, not overdrive: A new genetic route to fire blight resistance in apple
Fire blight remains one of the most destructive bacterial diseases threatening global apple production. A new study identifies a family of inducible lectin genes, MdAGGs, as critical components of apple immune defense and demonstrates that their precise activation timing is key to effective resistance.

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.

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.

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.

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.

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.
