PRP1 — Capsicum annuum

Summary

CaPRP1 (T459_23090) 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, as well as calcium signaling, immune response, defense response, cell death, response to heat, response to metal, and virus-induced PTGS. It is also linked to chromatin modeling and homeostasis. The encoded protein localizes 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 auxin-induced proteins and additional glutathione S-transferases.
