AGR — Oryza sativa Japonica

Summary

Rice gene OS11G0137000, also known as AGR, PIN1B, or OsEIR1, encodes a member of the auxin efflux carrier family (PIN-like proteins) and is annotated with auxin efflux transmembrane transporter activity, inositol-1,4-bisphosphate 1-phosphatase activity, and phosphatidylinositol phosphate binding. The gene is associated with plant height, tiller number, panicle and shoot architecture, root system development, and root growth angle. It is linked to cadmium, aluminium, phosphate, and oxidative stress, as well as to tropism, cell polarization, and endocytosis regulation. Associations with biological yield, panicle number, seed set, biomass yield, and nitrogen content further connect this gene to productivity-related traits. Studies of related genes in other species link it to phototropism, root patterning, and flowering time.
