AGR — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.7HG0739640 (HvAGR) on barley chromosome 7H encodes a PIN-like auxin efflux carrier with auxin efflux transmembrane transporter activity, inositol-1,4-bisphosphate 1-phosphatase activity, and phosphatidylinositol phosphate binding. The gene is associated with tropism, gravitropism, phototropism, and detection of oxidative stress. It has been linked to regulation of endocytosis, cell polarization, phragmoplast microtubule organization, and plant-type cell wall organization. Associations include gravity response, shoot growth angle, leaf vein morphology, seed set percent, relative root length, and brassinosteroid content. The gene is linked to auxin homeostasis, lateral root development, primary root growth, shoot apical dominance, pollen tube growth, and vein formation. Related genes in other species connect the family to tiller number, plant height, adventitious root emergence, chilling stress, and aluminium tolerance.
