Abstract

In order to understand of the molecular mechanisms of drought tolerance in sunflower, proteomic pattern of roots in two drought sensitive and drought-tolerant lines were evaluated under limited and favorable water conditions. After 2DE and comparison of relative abundance of protein spots using t test, 12 of 417 protein spots in sensitive and 17 of 467 in tolerant line were affected by drought stress significantly. Following nano-LC MS/MS the protein spots were identified using Mascot search engine in NCBI protein database considering more than 10 % sequence coverage and score of above 80. Cytoplasmic and nuclear proteins were the most proteins which were affected by water deficiency. Three protein spots i. e. Enolase, Glyceraldehyde 3-phosphate dehydrogenase and Chalcone synthase were expressed differentially in these lines. Reduction of Enolase as a sign of metabolic impairment could be resulted in downstream process under drought stress. Increased expression of Glyceraldehyde 3-phosphate dehydrogenase and Chalcone synthase could have a role in detoxification/removal of oxidative destruction and antioxidant capability of the tolerant line. Increased level of Heat Shock Protein, dihydroflavonol reductase, Seed linoleate 9S-lipoxygenase, Ubiquitin carboxyl-terminal hydrolase and G protein indicated crucial role of defensive, protective and transductive process in reduction of drought injuries.
