PRP1 — Capsicum annuum

Summary

CaPRP1 (T459_22736) 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_C_Tau, GSTU subfamily). In pepper, this gene is associated with diverse biological processes including toxin breakdown, hormone metabolism, response to metal, glutathione metabolism, calcium and auxin signaling, response to cytokinin, gibberellin, abscisic acid, and heat, as well as immune response, virus-induced PTGS, cell death, and defense response. It is linked to chilling stress response, net photosynthetic rate, photosynthetic rate, and chlorophyll content. The protein localizes to the cytoplasm. Studies of related GST family members in other species connect the family to drought tolerance and sensitivity, oxidative stress response, hydrogen peroxide content, quantum yield, lignin, starch, and anthocyanin content, seed maturation, and pathogen defense.
