Reinoculation and two-dimensional electrophoresis were performed to analyze the pathogenicity differentiation of Curvularia lunata.Resistant host inbred lines Shen135,Mo17,and 78599-1 were reinoculated(six generations) with low virulent isolate WS18.Results showed that the disease index had no significant change for the first 2 generations of inoculation.At the third generation,the incidence of disease was increased and the number of differential expressed proteins of mycelia were more than that in the first 2 generations.More than 100 differential expressed proteins were found in the mycelia of fifth generation when compared with the original one.In the experiment,10 differentially expressed proteins were identified by MALDI-TOF-MS analysis.Three proteins were related directly to the differentiation of virulence,2 were related to allergen,4 were related to the metabolism of carbon or signaling pathway and 1 was unkonwn to Curvularia lunata.
