prx — Pisum sativum

Summary

PSAT1G182960 (symbol prx, also known as PRXIIF) in garden pea (Pisum sativum) encodes a peroxiredoxin with thioredoxin domain and TPx activity (EC 1.11.1.25), placing it in the PRX5-like family. The gene is associated with cellular response to oxidative stress, cell redox homeostasis, hydrogen peroxide catabolic process, detoxification, wound healing, regeneration, and metabolic burst. Its product localizes to chloroplast stroma, mitochondrial lumen, cytosol, and cytoplasm. Studies of related genes in other species link the family to seed viability, seed weight, seed size, leaf size, plant height, chlorophyll content, lignin content, and drought tolerance.
