Abstract: The changes of protein in wheat plants, when inoculated by the pathogen of wheat powdery mildew (Blumeria graminis f. sp. tritici), were analyzed by using 2-dimentional electrophoresis techniques. The results showed that there are significant differences of proteins for both resistant wheat variety Pm3b and susceptible wheat variety Chancellor before and after infection of the pathogen. Some proteins were reduced or disappeared after affection in wheat. After the infection of pathogen, new proteins were induced in resistant variety Pm3b compared with those proteins before infection. Resistant variety, Pm3b, produced more than 20 new specific resistant proteins after inoculation compared with those proteins before infection. They may be the proteins associated with powdery mildew resistance.

Key words: Wheat, Powdery mildew, 2-dimentional electrophoresis, Protein
