FIGURE 7.

CaWRKY27 gene expression was induced by exogenously applied H₂O₂ in pepper plants. (A) CaWRKY27 expression in the leaves of WT pepper plants treated with H₂O₂ as determined by qRT-PCR. Relative CaWRKY27 expression levels were compared between H₂O₂-treated pepper plants and mock-treated control plants, which were set to a relative expression level of ‘1.’ Data represent the mean ± SE of three biological replicates, and asterisks indicate significant differences compared to control plants (SNK-test, ^∗P < 0.05 or ^∗∗P < 0.01). HPT, hours post treatment. (B) Seedlings carrying the pCaWRKY27::GUS construct were treated with H₂O₂ (10 mM) for 3 h. The a1-shoot, a1-root, a2-shoot, and a2-root, photographs are magnified images of the shoot or root of the corresponding a1 or a2 seedlings.
