PRP1 — Capsicum annuum

Summary

CaPRP1 (T459_25929) on pepper chromosome 10 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). It 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, virus-induced PTGS, cell death, and chromatin modeling. The gene is linked to chilling stress response, net photosynthetic rate, photosynthetic rate, and chlorophyll content. 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. The protein localizes to the cytoplasm.
