Legume Microbiomes in Development and Environmental Stress Resilience

Legumes host diverse microbial communities, including rhizobia, arbuscular mycorrhizal fungi, endophytes, plant-growth-promoting rhizobacteria, biocontrol microbes, and complex rhizosphere microbiomes. These microorganisms play essential roles in symbiotic nitrogen fixation, nutrient acquisition, root and nodule development, hormone homeostasis, immune modulation, pathogen suppression, and adaptation to environmental stresses. Understanding the ecological rules, functional traits, and molecular mechanisms that govern legume-associated microbiomes is critical for developing microbiome-based strategies to improve crop resilience and sustainable agriculture.This Research Topic aims to highlight recent advances in the microbiology of legume-associated microbial communities. We particularly welcome studies addressing how microbial community assembly, microbial functional traits, microbial metabolites, interkingdom interactions, and host-microbe signaling shape legume performance under changing environments. Special attention will be given to rhizobial symbiosis, rhizosphere and endosphere microbiomes, microbial mediation of abiotic and biotic stress tolerance, microbe-microbe interactions, synthetic microbial communities, microbial inoculants, and multi-omics approaches for resolving microbial functions in legume systems.We welcome Original Research, Reviews, Mini Reviews, Methods, and Perspectives articles focusing on the diversity, assembly, function, mechanism, and application of legume-associated microorganisms.Topics are welcomed but not limited to:o Diversity, assembly, and succession of legume-associated microbiomes in the rhizosphere, endosphere, phyllosphere, seed, and noduleso Rhizobial symbiosis, nodule colonization, strain competitiveness, and symbiotic nitrogen fixation under stress conditionso Roles of bacteria, fungi, and microbial consortia in drought, salinity, heat, cold, nutrient limitation, heavy-metal stress, and soil-borne disease resistanceo Microbial metabolites and functional traits, including phytohormones, volatile organic compounds, exopolysaccharides, siderophores, antibiotics, lipopeptides, and quorum-sensing moleculeso Microbe-microbe and host-microbe interactions among rhizobia, mycorrhizal fungi, endophytes, PGPR, pathogens, and biocontrol microbeso Microbiome-mediated regulation of root architecture, root hair development, infection thread formation, nodule organogenesis, and nodule maturationo Microbial modulation of plant immunity, hormone homeostasis, and growth-defense balance in legumeso Metagenomics, metatranscriptomics, metaproteomics, metabolomics, culturomics, spatial microbiome analysis, and multi-omics approaches for studying legume microbiomeso Design, stability, field performance, and ecological safety of synthetic microbial communities, biofertilizers, biocontrol agents, and microbial inoculantso Microbiome engineering strategies for improving nitrogen fixation, nutrient use efficiency, soil health, disease suppression, stress resilience, and yield stability in legume crops Topic editors: Yongxin Lin, Ziqin Pang, Qurban Ali Source: https://www.frontiersin.org/research-topics/83701/legume-microbiomes-in-development-and-environmental-stress-resilience
