PRP1 — Capsicum annuum

Summary

CaPRP1 (T459_03063) on pepper chromosome 1 encodes a glutathione S-transferase (GST) with glutathione transferase activity (EC 2.5.1.18), belonging to the Tau-class and thioredoxin-like superfamily. The gene is associated with glutathione metabolism, hormone metabolism including auxin, gibberellin, abscisic acid and cytokinin signaling, calcium signaling, and chromatin modeling. It is linked to immune and defense responses, cell death, virus-induced PTGS, response to heat, response to metal, and homeostasis. The protein localises 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 support the family's involvement in stress and hormone responses.
