| Abstract | Fungal endophytes are widely distributed endosymbionts that colonize intercellular and intracellular plant spaces and do not cause plant disease. Their plant-growth-promoting properties and dependence on plant responses to a variety of abiotic stresses have recently been investigated. Abiotic stress conditions such as heat, drought, cold, oxidative stress, heavy metal toxicity, high soil salinity are commonly encountered adverse environmental conditions that affect and hinder crop productivity around the world. Fungal endophytes, therefore, offer a promising opportunity to address the limitations of abiotic stress on crop growth. Endophytic fungal species can specifically enhance plant growth by biological nitrogen fixation, production of phytohormones, solubilization of phosphates, inhibition of ethylene biosynthesis, and promotion of host tolerance to abiotic stress either by induction of plant resistance or through production of secondary metabolites such as enzymes, siderophores, and antibiotics. It has been enumerated that even under unfavorable environmental circumstances, such as humidity, salinity, drought, heavy metal and nutrient stresses, fungal endophytes control the growth of the plant by different pathways necessary for maintaining balanced growth of the plant amidst such stresses. This chapter mainly highlights the essential role of fungal endophytes in plant growth and development, especially in relation to their stimulatory role in plant resistance against abiotic stress. In particular, the chapter underscores the role of fungal symbioses in abiotic stress tolerance in plants. Moreover, in view of the increasing global food insecurity exacerbated by intensifying agrarian crisis, the chapter also entails an account of novel strategies for the application of endophytic fungal inoculants in agricultural fields, especially for their role in combating abiotic stresses. The latter are implicated for their role in taking a heavy toll on global crop production and productivity. |
