AGR — Beta vulgaris subsp. vulgaris

Summary

BvAGR (BVRB_3G063100) encodes a protein with auxin efflux carrier domains and is annotated with both auxin efflux and influx transmembrane transporter activities, as well as inositol-1,4-bisphosphate 1-phosphatase activity and multiple phosphatidylinositol phosphate binding functions. This sugar beet gene on chromosome 3 is associated with tropism, phototropism, gravitropism, and blue light sensitivity, along with regulation of endocytosis, phragmoplast microtubule organization, and anthocyanin accumulation in response to UV light. It is linked to numerous developmental traits including root and shoot growth, lateral root number, root hair density and length, leaf vein morphology, shoot branching, stamen and anther morphology, seed set, and petiole length. The gene is also associated with auxin homeostasis, vascular development, pollen tube growth, and responses to oxidative stress, boron levels, and osmotic stress. Related genes in other species link the family to fruit development, flowering time, and root patterning.
