The root endophytic fungus Serendipita indica (S. indica) acts as a bio-fertilizer, immuno-modulator, stress-buster and enhances plant growth, and protects the host plant from various biotic and abiotic stresses. Recent high-throughput omics approaches have helped in understanding the role of S. indica in host plants under stress conditions. The present review focuses on the mechanism of S. indica mediated drought-tolerance in crops by analyzing morphological, physiological, biochemical, and molecular processes. Interactions of S. indica with other plant growth-promoting microorganisms have also been discussed. The knowledge gap and future prospects have also been pointed out.

根内生真菌Serendipita indica ( S. indica ) 作为生物肥料、免疫调节剂、胁迫破坏者和促进植物生长，并保护宿主植物免受各种生物和非生物胁迫。最近的高通量组学方法有助于了解S. indica在胁迫条件下在宿主植物中的作用。本综述通过分析形态、生理、生化和分子过程，重点研究籼稻介导的作物耐旱机制。还讨论了S. indica与其他植物生长促进微生物的相互作用。还指出了知识差距和未来前景。
