- Abstract
Salt stress is a globally increasing environmental detriment to crop growth and productivity. Exposure to salt stress evokes a complex medley of cellular signals, which rapidly reprogram transcriptional and metabolic networks to shape plant phenotype. To date, genetic engineering approaches were used with success to enhance salt tolerance; however, their performance is yet to be evaluated under realistic field conditions. Regulatory short non‐coding RNAs (rsRNAs) are emerging as next‐generation candidates for engineering salt tolerance in crops. In view of this, the present review provides a comprehensive analysis of a decade's worth of functional studies on non‐coding RNAs involved in salt tolerance. Further, we have integrated this knowledge of rsRNA‐mediated regulation with the current paradigm of salt tolerance to highlight two regulatory complexes (RCs) for regulating salt tolerance in plants. Finally, a knowledge‐driven roadmap is proposed to judiciously utilize RC component(s) for enhancing salt tolerance in crops.
