Abstract Globally, substantial research into endophytic microbes is being conducted to increase agricultural and environmental sustainability. Endophytic such as bacteria, actinomycetes, fungi inhabit ubiquitously within the tissues of all plant species without causing any harm or disease. Endophytes form symbiotic relationships with diverse can regulate numerous host functions, including resistance abiotic biotic stresses, growth development, stimulating immune systems. Moreover, endophytes play a dominant role in nutrient cycling, biodegradation, bioremediation, are widely used many industries. have stronger predisposition for enhancing mineral metal solubility by cells through secretion organic acids low molecular weight metal-specific ligands (such siderophores) that alter soil pH boost binding activity.
