ANTI-STRESS PHYTOHORMONES IMPACT ON PROTEOME PROFILE OF GREEN GRAM (VIGNA RADIATA) UNDER SALT TOXICITY

Green gram (Vigna radiata) is considered the chief legume in Pakistan. Thus, current study was conducted to examine the ameliorating effect of phytohormones pre-treatments under salt stress on proteome profile of green gram by sodium-dodecyl-sulphate-polyacrylamide gel electrophoresis (SDS-PAGE). The soluble green gram seedlings proteins were resolved on 4% stacking and 12% resolving gels. The SDS-PAGE resolved 24 polypeptide bands ranging from 200 to 17kDa. Among these, 12 out of 24 bands of proteins were essentials house-keeping or growth proteins of green grams. While, 120, 114.6, 51.8, 29.1, and 22.8 kDa bands were over-expressed under 50 to 350mM salt with phytohormones treatments. The others 104.5 kDa, 99.8 kDa, 95.3 kDa, 91.0 kDa, 55 kDa, 46 kDa, and 17kDa bands were related to the GAᴣ, IAA, and SA induced tolerance. Overall 120 kDa, 114.6 kDa, 104.5 kDa, 99.8, 95.3 kDa, 51.8 kDa, 29.1 kDa and 22.8kDa bands were first time identified in the current study. The information retrieved from NCBI protein database, the resolved peptides were principally belonging to 7S and 8S vicilin, 2S, 8S, 11S, and 16.5S globulins. It is determined that seed priming with SA enhanced tolerance in green gram by rapidly synthesizing stress alleviating peptides.
