AKR — Phaseolus vulgaris

Summary

PHAVU_002G104000, designated PvAKR, encodes a protein containing ankyrin repeat domains and exhibits DXP-synthase activity, along with identical protein and general protein binding. This French bean gene on chromosome 2 is associated with the MEP pathway, terpenoid and chlorophyll anabolism, secondary metabolism, detoxification, and membrane transport. It is linked to nodulation, arbuscular mycorrhizae formation, and responses to symbiotic bacteria and fungi. PvAKR localises to the periarbuscular membrane, plasmalemma, cytoplasm, and nucleus. The gene has been connected to traits including variegated leaf, carotenoid and chlorophyll content, photosynthetic rate, chloroplast development, embryo development, dwarfism, and resistance to Spodoptera littoralis. Studies of related genes in other species link the family to plastid differentiation, leaf variegation, and photosynthesis rate.
