PRP1 — Capsicum annuum

Summary

CaPRP1 (T459_23091) on pepper chromosome 9 encodes a glutathione S-transferase (GST) with glutathione transferase activity (EC 2.5.1.18), belonging to the Omega/Tau-like family and containing a thioredoxin-like domain. This gene is associated with diverse biological processes including glutathione metabolism, hormone metabolism (auxin, gibberellin, abscisic acid, cytokinin signaling), calcium signaling, immune and defense responses, response to heat and metal, cell death, virus-induced PTGS, chromatin modeling, and homeostasis. It is localized to the cytosol and cytoplasm. CaPRP1 has been linked to chilling stress response, net photosynthetic rate, photosynthetic rate (CO2-based), and chlorophyll content. Related genes in other species connect the family to auxin-induced proteins and stress-responsive GST isoforms.
