PRP1 — Capsicum annuum

Summary

CaPRP1 (T459_23095) 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 glutathione metabolism, hormone metabolism (including responses to auxin, gibberellin, abscisic acid, and cytokinin), calcium signaling, and defense and immune responses. It has been linked to cell death, virus-induced PTGS, chromatin modeling, homeostasis, and responses to heat and metal. Localisation evidence places the product in the cytoplasm. CaPRP1 is also associated with chilling stress response, net photosynthetic rate, photosynthetic rate, and chlorophyll content. Studies of related genes in other species further link the family to auxin signaling and stress responses.
