Abstract/Description: | The research was conducted to explore and predict model of the mechanism of salt tolerance in mustard (Brassica juncea) using four genotypes CS 54 (salt tolerant variety), CS 52-SPS-1-2012 (salt tolerant mutant), CS 614-4-1-4-100-13 (salt sensitive mutant) and Pusa bold (salt sensitive variety) under saline irrigation water (ECiw 12, and 15 dS m-1). Genotype CS 52-SPS-1-2012 followed by CS 54 performed better under imposed salt stress due to differentially regulation of Na+ accumulation in the roots and main stem, restriction of Na+ influx from root to shoot, maintaining higher net photosynthetic traits under saline stress compared to CS 614-4-1-4-100-13 and Pusa bold. Further, expression profiling of salt responsive antiporters (SOS1, SOS2, SOS3, ENH1 and NHX1) and antioxidant (APX1, APX4, DHAR3 and MDHAR6) genes elucidated their involvement in different components of salt tolerance mechanism including; ion efflux from root to soil, ion accumulation in vacuoles, retrieval of ions from xylem and increased tissue tolerance to high concentrations of toxic ions and accumulation of compatible solutes and significant role for imparting salt tolerance in Indian mustard. Predicted model based on these results, suggested the tree-fold effect of salt stress on mustard plants its counteract on these toxic paths for salt tolerance. |
