PRP1 — Capsicum annuum

Summary

CaPRP1 (T459_20472) on pepper chromosome 7 encodes a glutathione S-transferase (GST) with glutathione transferase activity (EC 2.5.1.18), belonging to the Omega/Tau-like family and containing thioredoxin-like and glutathione S-transferase domains. This gene is associated with diverse biological processes including hormone metabolism (auxin, gibberellin, abscisic acid, cytokinin signaling), calcium signaling, glutathione metabolism, immune and defense responses, response to heat and metal, cell death, virus-induced PTGS, and chromatin modeling. It is linked to chilling stress response, net photosynthetic rate, photosynthetic rate, and chlorophyll content. The product localizes to the cytosol and cytoplasm. Studies of related genes in other species connect the family to auxin-induced proteins and additional glutathione transferase isoforms.
