AGR — Oryza sativa Japonica

Summary

OS05G0576900, also known as AGR, PIN3B, or OsEIR1, encodes a member of the auxin efflux carrier family (PIN-like) on rice chromosome 5. The product possesses auxin efflux transmembrane transporter activity, inositol-1,4-bisphosphate 1-phosphatase activity, and binds various phosphoinositides and clathrin. This gene is associated with numerous biological processes including tropism, regulation of endocytosis, response to oxidative stress and cation stress, phosphoinositide-mediated signaling, and miRNA catabolism. It localizes to the auxin efflux carrier complex, basal and lateral plasma membranes, recycling endosomes, and clathrin-coated vesicles. In rice, the gene family has been linked to plant height, tiller number, root system architecture, aluminium tolerance, shoot architecture, and reproductive development. Additional associations include gravity response, tiller angle, panicle number, seed set, nitrogen content, phototropism, and biomass yield.
