ABCG5 — Phaseolus vulgaris

Summary

PHAVU_009G156100, designated PvABCG5 on French bean chromosome 9, encodes an ABCG-type transporter with ATP hydrolase activity and ATP-coupled transmembrane transporter activity. The gene is associated with suberin biosynthesis, Casparian strip and periarbuscular membrane localisation, and processes including bile acid secretion, potassium and sodium ion homeostasis, cellular osmotic and salinity responses, green leaf volatile biosynthesis, arbuscular mycorrhizae formation, and regulation of secondary shoot formation. PvABCG5 has been connected to waterlogging tolerance, cuticular wax content, and anthocyanin pigmentation. Studies of related genes in other species link the family to seed dormancy.
