AGR — Cucumis sativus

Summary

CsAGR (CSA_1G025070) on cucumber chromosome 1 encodes a protein with auxin efflux carrier and auxin influx transmembrane transporter activities, along with inositol-1,4-bisphosphate 1-phosphatase activity and multiple phosphatidylinositol phosphate binding capabilities. The gene is associated with auxin signalling, transport, and metabolism pathways, and is linked to tropism, phosphoinositide-mediated signaling, anthocyanin accumulation in response to UV light, and regulation of endocytosis. CsAGR has been connected to numerous agronomically relevant traits including fruit length and shape, seed set percent, leaf vein morphology, shoot growth angle, lateral root number, phototropism and gravity response traits, auxin content, and brassinosteroid content. The gene product localizes to the auxin efflux carrier complex, basal plasma membrane, recycling endosome, and clathrin-coated endocytic vesicles. Related genes in other species are linked to root patterning, phototropism, gravitropism, and vascular development.
