The transcriptional analysis of pepper shed light on a proviral role of light-harvesting chlorophyll a/b binding protein 13 during infection of pepper mild mottle virus.

ABSTRACT: Pepper mild mottle virus (PMMoV), a member of the genus Tobamovirus, causes severe damage on pepper worldwide. Despite its impact, the pathogenicity mechanisms of PMMoV and the pepper plant's response to infection remain poorly understood. Here, we compared the transcriptomic changes in a susceptible pepper inbred line 21C241 with a resistant inbred line 21C385 seedlings, following systemic PMMoV infection using RNA sequencing. Our results revealed that PMMoV induced more pronounced mosaic symptoms and higher viral accumulation levels in the susceptible line 21C241 compared to the resistant line 21C385. We identified 462 and 401 differentially expressed genes (DEGs) in the systemically-infected leaves of the susceptible and resistant lines, respectively, when compared to their healt
