The soil?plant microbiome plays a vital role in enhancing plant growth, stress tolerance and soil health under changing climatic conditions. Beneficial microorganisms improve plant resilience to drought, salinity, temperature extremes and flooding through mechanisms such as nutrient mobilization, phytohormone regulation, antioxidant production and induced systemic resistance. They also contribute to soil fertility by driving nutrient cycling, improving soil structure and increasing organic matter. In addition, soil microbes aid in climate change mitigation through carbon sequestration and regulation of greenhouse gas emissions. Overall, microbiome-based approaches offer a sustainable strategy for improving crop productivity, reducing reliance on chemical inputs and supporting climate-smart agriculture.
