Plants are continuously confronted by a variety of environmental stresses at various stages in their development. Extremely harse environmental conditions lead to oxidative stress because of the toxicities of certain ions and the overproduction of reactive oxygen species. Various stress-tolerance strategies are triggered that help plants to overcome/mitigate the stress-induced deleterious effects. These include morphological adaptations, osmoregulation, and enhanced activities of enzymatic as well as nonenzymatic antioxidants. To some extent, these strategies do help plants withstand unfavorable environmental conditions; however, in order to meet the food needs of the increasing world population, we have to develop/implement strategies to induce enhanced stress tolerance potential in crop plants. In connection with this, exploiting the biological means to induce enhanced stress tolerance for sustainable crop productivity is one of the promising means. Arbuscular mycorrhizal fungi (AMF) form symbiotic associations with the majority of the plants, altering root morphology and physiology as well. AMF-infected plants show efficient nutrient uptake and have higher enzymatic activities. The review in this chapter encompasses the general information about AMF and their possible role in stress mitigation. |
