AR1 — Phaseolus vulgaris

Summary

PHAVU_009G036200, designated AR1 (also known as PvCPR1, PvATR1, or ATR1) on French bean chromosome 9, encodes a protein with NADPH-hemoprotein reductase activity, ferredoxin-NADP reductase activity, and binding capabilities for FAD, FMN, and NADP. The product belongs to the P450R, CysJ-like FAD-binding, and flavoprotein families. AR1 is associated with piperine and sesquiterpene biosynthetic processes, phenylpropanoid metabolism, nitric oxide storage, and response to oxidative stress. It localizes to chloroplast thylakoid membrane protein complexes, the endoplasmic reticulum, stress granules, and the cytosol. The gene is linked to indole-3-acetic acid (IAA) content and, through related genes in other species, to glucosinolate biosynthesis, insect resistance, tryptophan and brassinosteroid biosynthesis, and indolic glucosinolate accumulation.
