Role of Antioxidant Enzymes, Hydrogen Peroxide and PRProteins in the Compatible and Incompatible Interactions of Cowpea (Vigna unguiculata) Genotypes with the Fungus Colletotrichum gloeosporioides

Several diseases, such as anthracnose, which are caused by the fungus species Colletotrichum gloeosporioides, negatively affect the cultivation of the cowpea (Vigna unguiculata). This work was conducted to measured the time-course activities and evaluate the possible roles of superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX) and hydrogen peroxide (H2O2), and the pathogenesis-related proteins (PR-proteins), peroxidase (POX), β-1,3-glucanase (GLU) and chitinase (CHI), in the resistant (TE97) and susceptible (BR3) cowpea genotypes in response to C. gloeosporioides infection.
