Defense priming of CaTin1, CaPR4, and CaPR1 genes in strain INR7, BTH, INR7 + BTH, and water-treated pepper plants by pathogen challenge under field condition. The expression levels of pepper defense-related genes CaTin1 (A), CaPR4 (B), and CaPR1 (C) and their normalized value of CaTin1 (D), CaPR4 (E), and CaPR1 (F) were quantified by qRT-PCR at 0 and 6 h after infilteration of X. axonopodis pv. vesicatoria at 106 cfu/ml 10 days after bacteria and chemical treatments. Bars represent mean ± SEM with four replications per treatment.
