AGR — Beta vulgaris subsp. vulgaris

Summary

BVRB_3G063090 (BvAGR) encodes a protein with auxin efflux carrier and inositol-1,4-bisphosphate 1-phosphatase activity, and belongs to the auxin efflux carrier family. The gene is associated with auxin influx and efflux transmembrane transporter activities, clathrin binding, and phosphoinositide-mediated signaling. It is linked to tropism, endocytic recycling, regulation of phragmoplast microtubule organization, and anthocyanin accumulation in response to UV light. BvAGR is associated with traits including gravity response, phototropism, root hair density and length, lateral root number, shoot growth angle, seed set percent, leaf vein morphology, and brassinosteroid content. It localizes to the auxin efflux carrier complex, recycling endosome, and clathrin-coated endocytic vesicle. Studies of related genes in other species link the family to root patterning, phototropic hypocotyl bending, and pollen tube growth.
