Endophytic fungi are microorganisms that live within the tissues of plants without causing any harm to the host plant. These fungi have been found to be present in a wide range of plant species, including both agricultural and wild plants. Endophytic fungi have been shown to play a variety of roles in plants, such as providing protection against pests and pathogens, enhancing plant growth, and aiding in nutrient uptake. Research into endophytic fungi has focused on understanding the diversity of these fungi, their interactions with host plants, and their potential applications in agriculture and medicine. Endophytic fungi are of interest because they have the potential to be used as biocontrol agents against plant pathogens, promote plant growth and increase crop yields, and produce bioactive compounds that could have pharmaceutical and industrial applications. Overall, research on endophytic fungi is a rapidly growing field that holds promise for developing sustainable and environmentally friendly solutions for agriculture and other industries.
