PRP1 — Capsicum annuum

Summary

CaPRP1 (T459_31161) on pepper chromosome 12 encodes a glutathione S-transferase (GST) with glutathione transferase activity (EC 2.5.1.18), belonging to the Tau-class and thioredoxin-like superfamily. 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, defense response, virus-induced PTGS, cell death, and chromatin modeling. 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 drought tolerance and sensitivity, oxidative stress response, hydrogen peroxide content, quantum yield, lignin and starch content, seed maturation, anthocyanin content, and pathogen defense.
