AGR — Zea mays

Summary

ZM00001EB194640, also known as AGR, ZmAGR, or ZmPIN1C, encodes a member of the PIN-formed family of auxin efflux carriers, characterized by an auxin efflux carrier domain and annotated with both auxin efflux and influx transmembrane transporter activities, as well as inositol-1,4-bisphosphate 1-phosphatase activity and phosphatidylinositol phosphate binding. In maize, this gene on chromosome 4 is associated with tropism, lateral growth, regulation of cell polarization, phragmoplast microtubule organization, endocytosis, and response to oxidative stress and cation stress. It is linked to traits including gravity and phototropism response, shoot growth angle, inflorescence branching, seed set, leaf vein morphology, root volume, liguleless, plastochron, and brassinosteroid content. Studies of related genes in other species connect the family to plant height, tillering, root architecture, pollen development, and aluminium tolerance.
