PRP1 — Capsicum annuum

Summary

CaPRP1 (T459_22737) 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 glutathione metabolism, toxin breakdown, hormone metabolism, and responses to auxin, cytokinin, gibberellin, abscisic acid, heat, and metals. It is also linked to immune response, cell death, calcium 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 and sensitivity, oxidative stress response, hydrogen peroxide content, quantum yield, lignin and starch content, seed maturation, anthocyanin content, and pathogen defense.
