AGR — Brachypodium distachyon

Summary

BdAGR (BRADI_1G31530V3) on chromosome 1 of Brachypodium distachyon encodes a PIN-like auxin efflux carrier family protein with auxin efflux transmembrane transporter activity, inositol-1,4-bisphosphate 1-phosphatase activity, and multiple phosphoinositide-binding functions. The gene is associated with auxin transport, gravitropism, tropism, endocytic recycling, regulation of cell polarization, phragmoplast microtubule organization, and responses to oxidative stress, cation stress, and boron levels. It is linked to flower formation, stigma development, and plant organ boundary formation. Associations with traits include gravity response, phototropism, shoot growth angle, leaf vein morphology, seed set percent, root length, shoot axis branching, stamen and anther morphology, and sensitivity to blue light, ethylene, gibberellic acid, and osmotic stress. Studies of related genes in other species connect the family to plant height, tillering, root architecture, pollen development, and aluminium tolerance.
