Drought is an abiotic stress that strongly influences plant growth, development and productivity. By proteomics study it is possible to identify the complex mechanism of water-stress response. The aim of this research was the analysis of wheat ( Triticum durum ) proteome changes under stress conditions by applying a severe water deficit treatment for 7 days. Stress-induced proteome changes were analyzed by two-dimensional gel electrophoresis in conjunction with matrix-assisted laser desorption ionization-time of flight mass spectrometry. Thirty-six protein spots showed a reproducible significant change between control and stressed samples. The reasonable implications in drought response of the identified proteins were discussed. Results provide new insights that can lead to a better understanding of the molecular basis of drought-sensitivity in plants. Therefore, the obtained data could suggest the development of drought resistant wheat varieties, in order to improve agricultural production in dry regions.
