AGR — Oryza sativa Japonica

Summary

OsAGR (OS06G0660200) on rice chromosome 6 encodes a protein with auxin efflux carrier activity, inositol-1,4-bisphosphate 1-phosphatase activity, and phosphatidylinositol phosphate binding, placing it in the PIN-like auxin transport family. The gene is associated with plant height, tiller number, root system architecture, root growth angle, adventitious root emergence, aluminium tolerance, and reproductive development in rice. It is linked to biological processes including tropism, regulation of endocytosis, response to oxidative stress, and phosphoinositide-mediated signaling, and localizes to the auxin efflux carrier complex, basal plasma membrane, and recycling endosome. Associations also connect OsAGR to gravity response, tiller angle, panicle number, seed set, nitrogen content, and blue light sensitivity. Studies of related genes in other species link the family to phototropism, root patterning, and flowering time.
