OsWNK9 regulates the expression of key transcription factors, phytohormonal, and transporters genes to improve salinity stress tolerance in rice.

ABSTRACT: Rice is a staple food crop, and salinity stress severely hinders its growth and yield. Understanding the molecular mechanisms regulating salinity tolerance is essential and requires the identification and functional characterization of salt-tolerant genes to develop rice varieties with increased tolerance to salinity stress. With No Lysine Kinases (WNKs) are serine/threonine kinases involved in various abiotic stress responses. Earlier, we reported that overexpression of OsWNK9 mitigates salinity stress in Arabidopsis and rice. In the present study, we used transcriptomic analysis to provide molecular insights into the tolerance mechanism exhibited by the overexpression line of OsWNK9 (Oe-OsWNK9) under salinity stress. RNA-seq analysis revealed that the Oe-OsWNK9 exhibited significant enri
