Endophytic Microbiota of Rice and Their Collective Impact on Host Fitness

Endophytic microbiota mainly includes positive modulator of plant growth, productivity, stress tolerance and ability to control the phytopathogens. Rice endophytes colonize in different parts like roots, shoots, leaves, seeds, flowers, ovules, etc. The diversity and colonization of endophytes depend on several factors like host specificity, environment specificity, chemotaxis, motility, etc. A mutualistic relationship between rice plant and their endophytes improves the host health. Several crucial activities of rice plants are influenced by the presence of endophytes as they endorse plant growth by producing different phytohormones, solubilized minerals, or mitigating various environmental adverse conditions. Endophytes also protect rice plants from various phytopathogen by the production of secondary metabolites, lytic enzymes, antibiotics and induced systemic acquired resistance. Furthermore, the endophytes from rice and major crops are recently been shown useful in environmental waste management and also for the synthesis of green nanoparticles. This study highlights the beneficial interaction between rice plants and their endophytic microbiota with special emphasis on highlighting their application for sustainable agricultural and environmental practices in order to enhance the agro-economy in an eco-friendly manner.
