Endophytes are microorganisms that live within the tissues of plants without causing any apparent harm to the host. These organisms can be bacteria, fungi, or other microbes, and they have been found in nearly all plant species studied to date. Endophytes are believed to play a variety of important roles in plant health and growth, including enhancing nutrient uptake, improving tolerance to stress, and protecting against pathogens. Research on endophytes has focused on understanding the diversity of these microorganisms, their interactions with host plants, and their potential applications in agriculture and biotechnology. Some endophytes have been shown to promote plant growth and increase crop yield, while others have biocontrol properties that can help protect plants from diseases. Overall, the study of endophytes is an important area of research with the potential to contribute to sustainable agriculture and environmental management.
