AGR — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.3HG0284930 (HvAGR) on barley chromosome 3H encodes an auxin efflux carrier of the PIN-like family, with annotated molecular functions including auxin efflux and influx transmembrane transporter activities, inositol-1,4-bisphosphate 1-phosphatase activity, and phosphatidylinositol phosphate binding. The gene is associated with tropism, detection of oxidative stress, regulation of cell polarization, endocytic recycling, and phragmoplast microtubule organization. It is linked to traits including gravity response, phototropism, shoot growth angle, leaf vein morphology, seed set percent, root length, anther and stamen morphology, brassinosteroid content, and responses to blue light, manganese, and ethylene. Studies of related genes in other species connect the family to plant height, tiller number, root system architecture, pollen development, and tolerance to chilling, cadmium, and aluminium.
