AGR — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.3HG0275200, designated HvAGR on barley chromosome 3H, encodes an auxin efflux carrier of the PIN-like family with auxin efflux transmembrane transporter activity, inositol-1,4-bisphosphate 1-phosphatase activity, and phosphatidylinositol phosphate binding. The gene is associated with auxin signalling and transport pathways, tropism, regulation of cell polarization, endocytic recycling, and response to oxidative stress and cation stress. It is linked to traits including gravity response, phototropism, root and shoot growth angles, seed set, leaf vein morphology, stamen and anther morphology, adventitious root formation, and sensitivity to blue light, ethylene, and osmotic stress. Related genes in other species are linked to plant height, tiller number, root system architecture, pollen development, and aluminium tolerance.
