Plant-microbe interactions in sustainable agriculture: Emerging trends and innovations

Agricultural enhance over the past five decades has led to soil degradation, biodiversity loss, and declining crop productivity, taking a transition toward sustainable production systems. The rhizosphere, a metabolically active zone, hosts diverse microbial communities that regulate nutrient cycling, plant health, and stress tolerance. Plant–microbe interactions range from symbiosis to pathogenic associations, significantly promoting soil fertility and crop performance. However, their application remains constrained by inconsistent field performance, limited scalability of laboratory findings, and insufficient understanding of microbiome stability under variable environmental conditions, along with regulatory and formulation challenges. This mini-review synthesizes key mechanisms of beneficial interactions, including biological nitrogen fixation, phosphate solubilization, and phytohormone production, while highlighting emerging approaches such as synthetic microbial consortia and multi-omics technologies. Evidence from field studies indicates that optimized microbial inoculants enhance nutrient use efficiency and stress resilience. Bridging research gaps through interdisciplinary approaches and supportive policies is essential for advancing sustainable agriculture.
