PRP1 — Capsicum annuum

Summary

CaPRP1 (T459_23071) 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). It is associated with diverse biological processes including glutathione metabolism, toxin breakdown, hormone metabolism, and responses to auxin, abscisic acid, cytokinin, gibberellin, heat, metal, and immune defense. The gene is also linked to cell death, calcium signaling, auxin signaling, virus-induced PTGS, chromatin modeling, and homeostasis. Localized to the cytoplasm, CaPRP1 is associated with chilling stress response, net photosynthetic rate, photosynthetic rate, and chlorophyll content. Studies of related genes in other species link the family to drought tolerance, oxidative stress response, hydrogen peroxide content, and pathogen defense.
