(A, B) Expression of eight group III WRKY genes in the leaves and roots of pepper plants after 24 h of exposure to Cd stress and Fe deficiency, as determined by RT–qPCR analysis. The relative expression of the genes in stressed plants was compared with that of control untreated (CK) plants, which was set to a value of 1. Data represent the mean ±SE of three biological replicates. Asterisks indicate significant differences compared with CK plants (Student’s t-test; *P<0.05, **P<0.01).
