Salt tolerance, in the biological process context, refers to the integrated physiological, cellular, and molecular mechanisms that enable organisms, particularly plants and some microbes, to maintain growth and viability under elevated external salinity. It encompasses ion homeostasis (e.g., selective uptake, compartmentalization of Na⁺ and Cl⁻, and maintenance of K⁺/Na⁺ ratios), osmotic adjustment via synthesis or accumulation of compatible solutes, regulation of water status, and activation of stress-responsive signaling pathways and transcriptional networks. These processes mitigate ion toxicity, oxidative stress, and metabolic disruption, thereby preserving membrane integrity, enzyme function, and overall cellular homeostasis in saline environments.
Salty soil is a growing threat to crops worldwide. Hotter, drier weather has increased evaporation rates, drawing moisture from the soil and leaving behind concentrated mineral salts. At the same time, water shortages are ...
