In order enhance performance model, modeling method Boruta algorithm combined with ELM was proposed. employed feature variables that exhibit strong content. These selected were utilized as inputs RP2, RMSEP, MAPEP Boruta-ELM being 0.9631, 71.4423, 10.06%, respectively. Then, genetic (GA) used optimize parameters GA-Boruta-ELM 0.9962, 11.005, 1.66%, findings demonstrate exhibits excellent capability effectively predicts contents samples.

Abstract Tryptophan decarboxylase (TDC) belongs to a family of aromatic amino acid decarboxylases and catalyzes the conversion tryptophan tryptamine. It is enzyme involved in first step melatonin (MT) biosynthesis mediates several key functions abiotic stress tolerance. In Oryza sativa under pesticide‐induced stress, TDC function unclear. Three differentially expressed genes (DEGs) six TDC‐coding were found be fluroxypyr‐meptyl (FLUME)‐treated rice transcriptome datasets, which allowed researchers explore properties roles stress. By applying sequence alignment phylogenetic analysis, two subfamilies gene family—DUF674 AAT_I—were rice, Glycine max , Zea mays Hordeum vulgare Solanum lycopersicum . According chromosomal location studies, segmental duplication aided expansion OsTDC family, three DEGs irregularly distributed on its 12 chromosomes. addition, nine displayed collinear relationship with those soybean, maize, barley, tomato. Rice can encode variety biotic responses because their diverse architectures, cis‐elements, motif compositions, conserved domains. Reverse transcription‐quantitative polymerase chain reaction (RT‐qPCR) analysis confirmed that proportion ( Os08g0140300 Os08g0140500 Os10g0380800 ) preferably 0.08 mg L −1 FLUME 5.2‐, 3.2‐, 3.9‐fold increase roots 2.1‐, 2.4‐, 2.6‐fold shoots, respectively. MT treatment further increased expression these genes, 2.1‐fold, 3.1‐fold, fivefold 1.5‐, 1.1‐, 1.1‐fold shoots than treated only, When seedling subjected activity was by 2.7 1.6 times higher control, application also promoted tissues; twofold 1.4‐fold higher, respectively, alone. These findings indicate respond effectively could enhance comprise set candidate regulate pesticide metabolism degradation MT.

Abstract BACKGROUND Rice blast, caused by Pyricularia oryzae , is a devastating fungal disease threatening global rice production. Overreliance on chemical fungicides has raised environmental concerns and led to resistant strains, necessitating the development of sustainable alternatives. This study integrated marine microbiology natural antifungal compounds create eco‐friendly alternatives for management. RESULTS We identified Pseudomonas aeruginosa R64 with broad‐spectrum antimicrobial activity from mangrove soil in Mai Po Nature Reserve. The fermentation extract (RFE) exhibited multifaceted inhibition P. suppressing mycelial growth, conidiation, conidial germination appressorial formation, while disturbing cell wall membrane function. It also attenuated virulence impairing penetration invasive growth. Further analysis phenazines quinolines as primary RFE, corroborated PCR detection corresponding phenazine biosynthetic gene clusters. Comparative bioassays two main bioactive components phenazine‐1‐carboxamide (PCN) phenazine‐1‐carboxylic acid (PCA), against implicated PCN principal effector. RFE had higher efficacy than tricyclazole growth inhibition, but were less effective isoprothiolane. Furthermore, displayed lower acute ecotoxicity an indicator organism isoprothiolane, suggesting their potential biopesticides blast CONCLUSION Natural products bacterium inhibited key developmental infection processes effectively reducing development. promising low mangrove‐associated bacteria highlight untapped innovative, fungicide mining agriculture. © 2025 Author(s).

Background Nature-based management of vineyards is at the heart a sustainable development for next decades. Although much known about grapevine benefits from Arbuscular Mycorrhizal Fungi (AMF), little influence vineyard terroir and farming practices on AMF communities. Methods We examined relative effect wine agricultural (organic, conversion, conventional) abundance diversity across 75 distributed over 14 terroirs in 6 winegrowing regions France. estimate by measuring spore density root mycorrhization rates, characterize communities composition using metabarcoding sampling both compartments each vineyard. Results Organic slightly increases (spore rate). Vineyards under conversion organic display higher than conventional ones. Terroirs vary widely terms diversity, with median OTUs count per sample ranging 9 ( Côte des Blancs ) to 35 Gigondas ). The structured mainly lesser extent practice. partially explained distance decay soil properties, but majority variation still only identity. improve vineyards, possibly leading more productivity resilience grapevines. Conclusion This large-scale study highlights importance our understanding microbiome paves way incorporation microbial studies applications.

Plants in grasslands navigate a complex landscape of interactions including competition for resources and defense against pathogens. Foliar fungi can suppress plant growth directly through pathogenic interactions, or indirectly via host growth-defense tradeoffs. The exclusion foliar allows the reallocation from to reproduction. In addition, plants also invest photosynthates rhizodeposition, root exudates, which play significant role shaping rhizosphere microbial community. However, it remains unclear what impact has on allocation rhizodeposition composition Using 6-year fungicide study plots planted with 16 species native prairie plants, we asked whether influence common grass (Andropogon gerardii) legume (Lespedeza capatita). We found that increased aboveground biomass season-long production, but did not alter biomass, seed diversity. magnitude change production was significantly associated community paired fungicide-treated vs. control plots. These results suggest important coupling between fungal infection investment modify local soil
