salt stress responses on protein profile in vigna unguiculata l.

The present study was aimed to elucidate the salt tolerant, salt inducible and salt sensitive protein of the Vigna unguiculata by Sodium Deodyl Sulphate – Poly Acrylamide Gel Electrophoresis. Seedlings of Vigna unguiculata exposed to different environmental conditions exhibited a plethora of physio-chemical responses. The seedlings treated with various concentrations of NaCl at third day showed maximum of 85 bands, with nine active regions and their MW-Rf values ranged from 0.012 to 0.891. The seedlings treated with same experimental set up at fifth day showed maximum number of 63 bands with eight active regions and their MW-Rf values ranged from 0.108 to 0.891. On 5th day seedlings showed the isoperoxidase expression with various sizes of bands. The soluble protein showed a gradual increase during the initial stage and after fifth day there was gradual decrease in their content.
