To explore the effect of salt stress on photosynthetic
traits and gene expression in Indian mustard, four
genotypes CS 54 (national check for salinity), CS 52-SPS-
1-2012 (salt tolerant mutant), CS 614-4-1-4-100-13 (salt
sensitive mutant) and Pusa bold (high yielding variety)
were evaluated under irrigation water salinity (ECiw 12,
and 15 dS m-1). Results suggest genotype CS 52-SPS-1-
2012 followed by CS 54 performed better under imposed
salt stress due to differential 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, overexpression of antiporters
(SOS1, SOS2, SOS3, ENH1 and NHX1) and antioxidant
(APX1, APX4, DHAR1 and MDHAR) genes in salt tolerant
genotypes CS 52-SPS-1-2012 and CS 54 demonstrated
their significant role in imparting salt tolerance in Indian
mustard.
