AGR — Beta vulgaris subsp. vulgaris

Summary

BvAGR (BVRB_6G155380) on sugar beet chromosome Bvchr6_un.sca001 encodes a protein with auxin efflux carrier domains and annotated molecular functions including auxin efflux and influx transmembrane transporter activities, inositol-1,4-bisphosphate 1-phosphatase activity, and phosphatidylinositol phosphate binding. The gene is associated with auxin efflux transport, gravitropism, and responses to abiotic stimuli. It has been linked to numerous traits including gravity response, phototropism, root and shoot growth angles, lateral root number, root hair density and length, seed set, leaf vein morphology, stamen and anther morphology, stem senescence, and herbicide sensitivity. Phenotypic associations include primary root growth, root hair development, lateral and adventitious root organogenesis, shoot apical dominance, pollen tube growth, vein formation, and vascular development. Studies of related genes in other species link the family to root patterning, gravitropism, phototropism, and polar auxin transport.
