The objective of the present study was to assess the role of salinity-induced expression of pyrrolline 5-carboxylate synthetase (P5CS), P5CS activity, and proline accumulation on salinity tolerance in Brassica genotypes. A pot culture experiment was conducted with four Brassica genotypes viz. CS 52, CS 54, Varuna, (B. juncea) and T 9 (B. campestris) under control and two salinity levels, i.e., 1.65, 4.50 and 6.76 dS m⁻¹. Proline contents increased with increasing levels of salinity, and the highest content were recorded at post-flowering stage in CS 52 and CS 54. Activity of P5CS recorded at flowering stage was highest at higher level of salinity, with CS 52 and CS 54 recording highest activity. Gene expression of P5CS, which regulates the synthesis of proline, was higher in CS 52 and CS 54 under salt stress than Varuna and T 9. Comparison of partial nucleotide as well as amino acid sequence showed conserved domains, and inter and intra generic relatedness of these genes. The study suggests that salinityinduced expression of P5CS, pyrrolline-phosphate synthetase activity and proline accumulation may serve as one of the mechanism of salinity stress tolerance in Brassica genotypes.
