PRP1 — Capsicum annuum

Summary

CaPRP1 (T459_03058) on pepper chromosome 1 encodes a glutathione S-transferase (GST) with glutathione transferase activity (EC 2.5.1.18), belonging to the Tau-class GST family (GST_C_Tau, GSTU subfamily). 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 is associated with cell death, virus-induced PTGS, chromatin modeling, and homeostasis. CaPRP1 is linked to heat stress, metal response, and chilling stress response, as well as to photosynthetic traits including net photosynthetic rate, photosynthetic rate (CO2 assimilation), and chlorophyll content. The encoded protein localizes to the cytoplasm. Studies of related genes in other species link the family to auxin signaling and stress responses.
