The expression of the genes involved in redox metabolism and hydrogen peroxide balance is associated with the resistance of cowpea [Vigna unguiculata (L.) Walp.] to the hemibiotrophic fungus Colletotrichum gloeosporioides.

Résumé
Correlations between the transcriptional responses of genes that encode superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX), and peroxiredoxin (Prx) enzymes and Colletotrichum gloeosporioides development in cowpea leaves were assessed. Each of these genes is involved in the redox metabolism and hydrogen peroxide balance. Although electron microscopy revealed that conidia adhered to and germinated on the leaf cuticle, the inoculated cowpea leaves did not show any characteristic anthracnose symptoms. The adhered and germinated conidia showed irregular surfaces and did not develop further. This was apparently due to increased leaf H
