PRP1 — Capsicum annuum

Summary

CaPRP1 (T459_23070) on pepper chromosome 9 encodes a glutathione S-transferase (GST) with glutathione transferase activity (EC 2.5.1.18), belonging to the Tau-class GST family. The gene is associated with diverse biological processes including toxin breakdown, glutathione metabolism, hormone metabolism, calcium and auxin signaling, response to cytokinin, gibberellin, abscisic acid, heat, and metal, as well as immune response, cell death, and virus-induced PTGS. It is linked to chilling stress response, net photosynthetic rate, photosynthetic rate, and chlorophyll content. The protein localizes to the cytoplasm. Studies of related genes in other species connect the family to pathogen defense and pathogen response, while sequence similarity links the family to traits such as drought tolerance, oxidative stress response, and anthocyanin content.
