To better understand the adaptation mechanisms and differential expressed proteins of wheat to water-stress,a comparative proteome analysis was conducted in this study under normal water supply and-0.5MPa PEG-6000 solution using two-dimensional gel electrophoresis and mass spectrometry.Among 850 protein spots reproducibly detected under the two treatments,31 protein spots showed a reproducible significant change between control and stressed samples(P<0.05).Of these,17 protein spots under the stress conditio...
