Drought stress is one the most important stresses that diminish yield crops. Germination is first phase in plant cycles that damaged from this stress extremely. Drought stress effects many molecular activity as likes changes in proteome patterns in seed embryo axes especially. A study was conducted in order to understand the effects of drought stress on protein changes during germination. To examine the effects of drought stress (-12 bar) on wheat seed embryo (Sardari and Qods respectively tolerance and sensitive cultivars), factorial experimental was conducted in a block complete design with three replications under second germination phase. Results demonstrated that drought stress had inappropriate effects on germination percentage. According to the gels analysis, about 1000 repeatable spots in protein patterns was detected that 25 spots showed significant differences under control and drought stress. It appears that increases in proteins frequency in tolerance and sensitive cultivars related to proteins groups of stresses and carbohydrate metabolism, alpha-amylase inhibitors respectively .The results showed that the frequency of these proteins depends on severity and mount of stress and imbibition time.
