Osmotic stress caused by hyperosmotic soil solution disrupts plant cell turgor. The detrimental effects of elevated salinity on plants include (i) osmotic stress as sodium accumulates in the soil and (ii) ionic stress ( Figure 1) ( Yang and Guo, 2018a Yang and Guo, 2018b Ludwiczak et al., 2021). Salt stress causes plant growth inhibition, abnormal development, and metabolic disturbance ( van Zelm et al., 2020). About 2 million ha (~1%) of world agricultural land is under accelerating salinization each year ( Tuteja, 2007). It is estimated that crop production on at least 20% of global irrigated land is impaired. In addition to naturally occurring soil salinization, the situation is even exacerbated by excessive chemical fertilizers and soil amendments, improper irrigation practices, and the effect of seawater exposure ( Munns and Tester, 2008 Sahab et al., 2021). Soil salinization is one of the most adverse environmental stressors, severely limiting plant growth and development and threatening agricultural production worldwide. Finally, we also discuss the possible contribution of microbiota and nanobiotechnology to plant salt tolerance. This review summarizes the current research progress in the regulatory networks for plant salt tolerance, highlighting the mechanisms of salt stress perception, signaling, and tolerance response. Unraveling these adaptive mechanisms and identifying the critical genes involved in salt response and adaption are crucial for developing salt-tolerant cultivars. Plant responses to salt stress involve a series of biological mechanisms, including osmoregulation, redox and ionic homeostasis regulation, as well as hormone or light signaling-mediated growth adjustment, which are regulated by different functional components. Salt stress is one of the significant environmental stressors that severely affects plant growth and development. 2Key Laboratory of Bio-resource and Eco-environment of Ministry of Education, College of Life Sciences, Sichuan University, Chengdu, China.1Xinjiang Key Laboratory of Biological Resources and Genetic Engineering, College of Life Science and Technology, Xinjiang University, Urumqi, China.
