Endophytes are microorganisms, primarily fungi and bacteria, that live inside the tissues of plants without causing harm. They can be found in various plant species and often contribute to the plant's health by enhancing growth, improving nutrient uptake, and providing resistance to pests and diseases. These beneficial organisms can also produce bioactive compounds that may have pharmaceutical applications. Research into endophytes is growing, as scientists explore their potential in agriculture and medicine, aiming to harness their properties for sustainable practices and new treatments.
