CaSBP12 is implicated in pepper's defense resistance to Phytophthora capsici infection associated with the SA signaling pathway.

ABSTRACT:

Background

Pepper is a crucial vegetable crop with significant economic value, yet its yield and quality are severely affected by pepper Phytophthora Blight. Our previous research indicated that CaSBP12 negatively regulates pepper resistance to Phytophthora capsici (P. capsici) infection. However, the precise role of CaSBP12 in the defense response against P. capsici remains unclear. Thus, it is essential to investigate the defense mechanisms by which CaSBP12 contributes to pepper resistance against P. capsici infection.

Results

In this study, silencing CaSBP12 significantly increased the expression of defense-related genes (CaBPR1, CaSAR8.2, CaDEF1, CaPO1) in CaSBP12-silenced plants compared to controls after P. capsici inoculation. Even under normal conditions, these genes
