Jasmonic acid-mediated cell wall biosynthesis pathway involved in pepper (Capsicum annuum) defense response to Ralstonia solanacearum.

ABSTRACT: Ralstonia solanacearum is a destructive soil-borne pathogen that causes severe bacterial wilt (BW) disease in peppers. Phytohormone signaling pathways, including those mediated by jasmonic acid (JA), are crucial to plant defense responses against pathogen attacks. Nevertheless, the function of JA in the resistance response of pepper to R. solanacearum is unclear. Therefore, RNA sequencing (RNA-seq) and phytohormone determination experiments were performed to compare the dynamic transcriptome changes and differences in JA and salicylic acid (SA) contents between the resistant pepper line BVRC1 and the susceptible pepper line BVRC25 during R. solanacearum infection. The number of differentially expressed genes (DEGs) was greater in BVRC1 than in BVRC25 at 12, 24, 48, and 72 h post-infection.
