AKR — Phaseolus vulgaris

Summary

PHAVU_002G103900 (PvAKR) encodes a protein with ankyrin repeat domains and exhibits DXP-synthase, fatty-acyl-CoA binding, ubiquitin-protein transferase, and protein binding activities. In French bean, PvAKR is associated with the MEP pathway, terpenoid and chlorophyll biosynthesis, detoxification, nodulation, arbuscular mycorrhizae formation, embryo development, and responses to symbiotic bacteria and fungi. It localizes to the periarbuscular membrane, ER, cytosol, plasma membrane, and nucleus. The gene has been linked to traits including photosynthetic rate, chlorophyll content, chloroplast development, leaf variegation, plant growth, and resistance to Spodoptera littoralis. Phenotypic associations include embryo and gametophyte development, isoprenoid and carotenoid biosynthesis, carbon assimilation, and albinism rescued by DX supplementation. Studies of related genes in other species link the family to chloroplast differentiation, photosynthesis rate, and essential oil production.
