Project description:To investigate differentially accumulated proteins caused by transgenic events, comparative proteomic analysis using two-dimensional polyacrylamide gel electrophoresis was employed for Vitis vinifera ‘Thompson seedless’ leaves and transgenic Vitis vinifera ‘Thompson seedless’ leaves. Obtained proteins were digested with trypsin and subjected to MALDI-TOF-MS/MS analysis. According to annotations and a Blast search, proteins analyzed by MALDI-TOF/TOF were classified into 4 functional categories: carbon and energy metabolism, oxidation reaction, protein metabolism and resistance.

Comparative proteomics of salt stressed own rooted and 110R grafted Thompson Seedless grapevines

Project description:Salt stress is a rising threat to agriculture system. The accumulation of salts near the plant roots hampers the normal uptake of water causing osmotic stress and ionic toxicity to the plant. Thompson Seedless is a popular table grape variety of Vitis vinifera L., which is sensitive to salt stress when grown on its own roots; grafting it onto a wild rootstock such as 110 Richtor (110R) makes it tolerant to salt stress. In the present study, shotgun-proteomics approach was used for the investigation of salt stress induced molecular response of own rooted and 110R grafted Thompson Seedless grapevines. A salt stress experiment was conducted on sixteen month old potted grapevines. The grapevines were treated with 150mM NaCl solution for seven days and the control vines were irrigated with tap water. The young leaf samples were collected from control and treated vines at three time-points viz. 6 hours, 48 hours and 7 days of salt stress. The stress responsive proteins identified through statistical analysis revealed a distinct response to salinity in both the vines.
