AGR — Oryza sativa Japonica

Summary

Rice gene OS02G0743400, also known as AGR, PIN1A, WAV6, and OsEIR1, encodes a PIN-like auxin efflux carrier protein with auxin efflux transmembrane transporter activity, inositol-1,4-bisphosphate 1-phosphatase activity, and phosphatidylinositol phosphate binding. This gene is associated with plant height, tiller number, root system architecture, adventitious root emergence, root growth angle, inflorescence development, and reproductive development in rice. It is linked to tropism, regulation of endocytosis, cell polarization, phragmoplast microtubule organization, and response to oxidative stress, cation stress, and boron levels. The protein localizes to the auxin efflux carrier complex, basal plasma membrane, recycling endosome, and clathrin-coated endocytic vesicle. Studies of related genes in other species connect the PIN family to phototropism, root meristem growth, embryonic pattern formation, and flowering time.
