PLANT ENDOPHYTES: A NATURAL SOLUTION FOR SUSTAINABLE AGRICULTURE AND CROP PROTECTION

Endophytes are microorganisms that live within plant tissues without causing harm and play a crucial role in enhancing plant health and agricultural productivity. These beneficial microbes include bacterial genera such as Bacillus and Pseudomonas, as well as fungal species like Trichoderma and Fusarium. They establish symbiotic relationships with their host plants, contributing to plant growth through the production of phytohormones, aiding in nutrient solubilization, and improving resistance against both biotic and abiotic stresses. Endophytes have the ability to suppress pathogens, enhance drought and salinity tolerance, and mitigate oxidative stress, making them valuable in sustainable agriculture. Additionally, they produce a variety of secondary metabolites that possess antimicrobial properties and boost plant defense, offering potential alternatives to chemical fertilizers and pesticides. Despite their promising applications, there are challenges such as difficulties in isolation, variabilityin performance in the field and regulatory concerns that must be addressed for their widespread use. However, advances in biotechnology, including genetic engineering and omics technologies, are paving the way for improved applications of endophytes in agriculture. This review explores the diversity, mechanisms, and potential of endophytes in crop production, highlighting their role in promoting sustainable and eco-friendly farming practices.
