AGR — Oryza sativa Japonica

Summary

Rice gene OS06G0232300, also known as AGR, PIN1C, or OsEIR1, encodes a member of the auxin efflux carrier family, possessing auxin efflux transmembrane transporter activity, inositol-1,4-bisphosphate 1-phosphatase activity, and binding capabilities for various phosphatidylinositol phosphates and clathrin. The gene is associated with plant height, tiller number, root growth angle, adventitious root emergence, and reproductive development in rice. It has been linked to responses to cadmium, aluminium, phosphate, and oxidative stress, as well as tropism, cell polarization, endocytosis regulation, and phragmoplast microtubule organization. Localization evidence connects the encoded protein to the auxin efflux carrier complex, basal plasma membrane, recycling endosome, and clathrin-coated endocytic vesicle. Studies of related genes in other species link the family to phototropism, root patterning, embryonic development, and cadmium tolerance.
