ABSTRACTThe significant rise in soil salinity has had detrimental effects on global agricultural production, negatively impacting overall plant health and leading to a decline in productivity. As a protective response, plants have developed diverse regulatory mechanisms to counteract these adverse conditions. The mechanisms help mitigate damage caused by both osmotic and ionic stress resulting from high salinity. Given the severe threat this poses to global food security and the well‐being of the world's population, scientists have dedicated decades of research to understanding how to manage salt stress. Numerous mechanisms have been identified and studied to enhance plant salt tolerance and alleviate the damage caused by salt stress. This review examines recent advancements in molecular regulatory mechanisms underlying plant salt, including salt uptake and transport, salt sensing and signalling, hormonal regulation, epigenetic modifications, genetic adaptation, and posttranslational modifications. Although current knowledge has advanced our understanding, critical gaps and controversies remain, such as the stability of epigenetic memory, the trade‐off between stress tolerance and growth, hormonal crosstalk, and novel genes with uncharacterised roles in salt tolerance. To resolve these questions, further research employing techniques like GWAS, transcriptomics, transgenic and genome‐editing technologies, as well as studies on energy allocation and hormonal regulation, is essential. A deeper exploration of these complex, synergistic mechanisms will pave the way for enhancing plant resilience and ensuring adaptation to increasingly challenging environmental conditions.
