PRR1 — Capsicum annuum

Summary

CaPRR1 (T459_17091) on pepper chromosome 6 encodes a bifunctional pinoresinol-lariciresinol reductase with lariciresinol reductase, pinoresinol reductase and oxidoreductase activities, and also possesses DNA-binding transcription factor activity. The gene is associated with lignan biosynthesis and catabolism, including the anabolism and breakdown of pinoresinol, lariciresinol and secoisolariciresinol, as well as ether and phenol-containing compound metabolism. It is associated with positive regulation of photomorphogenesis, heterochronic development and filament development. Associations with agronomic traits include fruit color, carotenoid and anthocyanin content, flowering time, leaf and seed development, plant growth, peduncle length, stamen length, hypocotyl length, trichome morphology, and stress-related traits such as arsenic concentration and salt tolerance. The protein localises to the nucleus, cytoplasm, plasmodesma and stress granules.
