Optimizing the microbiome to improve plant stress resilience
Abstract
Plant-associated microbial consortia represent an indispensable component of the phytobiome, regulating plant growth, yield, and ecological resilience to both abiotic and biotic stresses through complex interactions among roots, soil, and associated microbes. Beneficial microorganisms, particularly plant growth-promoting rhizobacteria PGPR, arbuscular mycorrhizal fungi (AMF), and endophytes, enhance plant resistance to drought, salinity, heat, and pathogen attacks by regulating phytohormones, enhancing nutrient and water acquisition, and activating antioxidant and defense pathways. Strategies for microbiome optimization include microbial inoculants and synthetic microbial consortia, manipulation of root exudates, microbiome-aware breeding, and sustainable soil management practices that enhance microbial diversity and stability. Despite considerable progress, challenges remain in achieving consistent field-level performance due to issues of microbial specificity, persistence, and environmental variability. Emerging technologies such as integrated omics, systems biology, predictive modeling, and microbiome engineering offer new avenues for designing resilient and sustainable agroecosystems. This review synthesizes current knowledge on plant–microbiome interactions, highlights recent advances in microbiome optimization, and discusses future strategies for leveraging beneficial microbes to improve plant stress tolerance and promote climate-smart farming.
