AGR — Beta vulgaris subsp. vulgaris

Summary

BvAGR (BVRB_8G185310) on sugar beet chromosome 8 encodes a protein with auxin efflux carrier and transmembrane transporter domains, annotated with auxin influx and efflux transporter activity, inositol-1,4-bisphosphate 1-phosphatase activity, and phosphatidylinositol phosphate binding. The gene is associated with tropism, phototropism, gravitropism, root and shoot development, including primary root growth, lateral root number, root hair density and length, shoot branching, leaf vein morphology, stamen and anther traits, seed set, and responses to blue light, oxidative stress, boron, and osmotic conditions. It localizes to the auxin efflux carrier complex, basal plasma membrane, recycling endosome, and clathrin-coated vesicles, and is linked to phosphoinositide signaling, endocytosis, cell wall organization, and anthocyanin accumulation. Related genes in other species are associated with fruit development, flowering time, and stress tolerance.
