AGR — Oryza sativa Japonica

Summary

OsAGR (OS01G0715600) on rice chromosome 1 encodes a protein with auxin efflux carrier and auxin influx transmembrane transporter activities, along with inositol-1,4-bisphosphate 1-phosphatase activity, phosphatidylinositol phosphate binding, and clathrin binding. It belongs to the auxin efflux carrier family and is associated with plant height, tiller number, root growth angle, adventitious root emergence, aluminium tolerance, and shoot architecture in rice. The gene is linked to biological processes including tropism, detection of oxidative stress, regulation of endocytosis, phragmoplast microtubule organization, and response to cation stress. It localizes to the auxin efflux carrier complex, basal plasma membrane, recycling endosome, and clathrin-coated endocytic vesicle. Associations also include gravity response, tiller angle, panicle number, seed set percent, and nitrogen content. Studies of related genes in other species connect the family to phototropism, root patterning, and flowering time.
