    Abstract:
    Anthracnose represents an important disease of cowpea [Vigna unguiculata L. (Walp.)] caused by the hemibiothrophic fungus Colletotrichum gloeosporioides that drastically reduces cowpea field production. In this study we investigated some biochemical aspects underlying the incompatible interaction between a resistant cowpea genotype and C. gloeosporioides using a proteomic approach. Analyses of two-dimensional gel electrophoresis patterns and protein identification indicate C. gloeosporioides infection-dependent cowpea leaf proteome changes associated with metabolism, photosynthesis, response to stress, oxidative burst and scavenging, defense signaling, and pathogenesis-related proteins. Moreover the C. gloeosporioides responsive proteins interaction network in cowpea revealed the interconnected modulation of key cellular processes involving particularly antioxidants proteins, photosynthetic apparatus forming proteins and proteins of the energetic metabolism that interact with each other suggesting that their expression changes are also important for resistance of cowpea to C. gloeosporioides.
