PRXQ — Phaseolus vulgaris

Summary

PvPRXQ (PHAVU_003G128266) on French bean chromosome 3 encodes a peroxiredoxin of the BCP/PrxQ family, possessing thioredoxin-dependent peroxidase (TPx) and general peroxiredoxin activity, along with mRNA and protein binding capabilities. The product localizes to chloroplast thylakoid membranes, stroma, lumen, envelope, and cytosol. It is associated with cellular responses to oxidative stress, hydrogen peroxide catabolism, reactive oxygen species metabolism, cell redox homeostasis, and chlorophyll content. The gene is also linked to redox regulation, decreased cold stress response, and 16:1trans fatty acid biosynthesis. Related genes in other species are linked to oxidative stress response and fatty acid desaturation.
