Abstract
Modern agriculture is facing twin challenge of ensuring global food security and executing it in a sustainable manner. However, the rapidly expanding salinity stress in cultivable areas poses a major peril to crop yield. Salinization occurs naturally in arid and semiarid regions where evaporation is higher than rainfall. In India nearly 6.74 million ha area is occupied by salt-affected soils out of which 2.96 million ha are saline soils (including coastal) and 3.79 million ha are alkali soils (CSSRI, 2020). The higher salinity level poses adverse effects on soil properties and plant physiology (Rajput et al., 2015). In the natural environment, plants can be colonized both by external and internal microorganisms. The activity of soil microbial communities is considered the lifeline of global ecosystem productivity and sustainability. Arbuscular mycorrhizae (AM) are considered as bio-ameliorators of saline soils and could develop salinity tolerance in crop plants. AM fungi colonize plant root systems and modulate plant growth in various ways under abiotic stress. Indeed AMF improve physiological processes and general metabolic activities of the plant and helps in the mitigation of salinity. It enhance the production of Strigolactones in root system, Abscisic acid, Jasmonic acid, Glomalin and helps the roots in uptake of water and other nutrient under saline condition. Hence, the Mycorrhizal fungi offers a potential solution to combat salinity problem, helps to mitigate from the stress and increase crop growth under adverse condition.
