Abstract

Abstract: The protein of resistant corn variety QI 319 and susceptible variety 7922 was extracted from leaves and separated using two-dimensional polyacrylamidgel electrophoresis(2-D)at 3d after inoculating prevalent race QN-10 of Curvularia lunata. In QI 319,compared with control with no pathogen inoculation,12 novel proteins were induced;In 7922,three protein spots of and two protein spots of showed increase and decrease in protein abun-dance,respectively,but there were no hovel protein spots induced. Among the 12 hovel protein spots induced in QI 319,six spots were identified using MALDI-TOF-MS and NCBI database searching,which were F-box and leucine-rich repeat protein,heavy metal transport/detoxification protein,beta-1,3-glucanase and zinc finger protein.

Key words: Curvularia lunata, Maize, Proteome, β-1, 3-glucanase
