FP25020Impact of Helicoverpa armigera Hübner (Lepidoptera: Noctuidae) infestation and wounding on gene expression of defense-related genes and chlorophyll fluorescence in common bean
We examined the expression of four defense-related genes, PvPAL, PvLOX, PvGST, and PvPOD, in common bean under Helicoverpa armigera infestation and wounding. We found that all genes were significantly upregulated in response to H. armigera, with distinct expression profiles compared to wounding. Marked reductions in chlorophyll fluorescence parameters (Fv/Fm, PIABS, ETo/RC) were determined under both H. armigera infestation and wounding. In particular, findings highlight potential roles of PvLOX and PvGST genes in common bean’s defense against herbivory and wounding.
