PRX — Phaseolus vulgaris

Summary

PHAVU_006G151800, designated PvPRX, encodes a protein with a PRX5-like, redoxin, thioredoxin domain, and thioredoxin-like superfamily, exhibiting thioredoxin peroxidase (TPx) and peroxidase activity. In French bean (Phaseolus vulgaris) on chromosome 6, this gene is associated with cellular response to oxidative stress, cell redox homeostasis, reactive oxygen species metabolic process, hydrogen peroxide catabolic process, and DNA breakdown. The product localizes to mitochondria, chloroplast stroma, and cytosol. PvPRX is linked to chlorophyll content. Studies of related genes in other species connect this gene family to seed viability, seed weight, seed size, leaf size, plant height, lignin content, and drought tolerance, though these associations are not yet established for PvPRX itself.
