Functional Descriptions:

  • Overexpression of Rice Glutaredoxin OsGrx_C7 and OsGrx_C2.1 Reduces Intracellular Arsenic Accumulation and Increases Tolerance in Arabidopsis thaliana.
  • Gene expression analysis suggested that OsGrx_C7 expression was induced under salt stress and ubiquitously expressed in rice including root and shoot.
  • A gain-of-function approach showed that OsGrx_C7 may act as an important determinant in salt stress, compared with WT, and revealed higher biomass accumulation, improved root and plant growth under salt stress.
  • CC-type glutaredoxin, OsGrx_C7 plays a crucial role in enhancing protection against salt stress in rice.
  • Gene expression analysis, silencing, and overexpression of OsGrx_C7 gene were used to discover the role of OsGrx_C7 in response to salt stress.
  • The silencing of OsGrx_C7 gene leads to increased sensitivity to salt stress, indicating its importance in salt stress tolerance.
  • Under salt stress condition, OsGrx_C7 overexpressing rice plants showed lower level of lipid peroxidation and Na+/K+ ratio, while proline accumulation, soluble sugar content and GSH/GSSG ratio was higher compared to WT.
  • Furthermore, expression analysis suggested that OsGrx_C7 acted as positive regulator of salt tolerance by reinforcing the expression of transporters (OsHKT2;1, OsHKT1;5 and OsSOS1) engaged in Na+ homeostasis in overexpressing plants.
  • Overall our study revealed that OsGrx_C7 emerged as a key mediator in response to salt stress in rice and could be used for engineering tolerance against salt stress in rice and other crops.
