AGR — Brachypodium distachyon

Summary

BdAGR (BRADI_2G15610V3) on chromosome 2 of Brachypodium distachyon encodes a member of the PIN-like auxin efflux carrier family, possessing auxin efflux transmembrane transporter activity and inositol-1,4-bisphosphate 1-phosphatase activity. The gene is associated with auxin signalling, clathrin-mediated endocytosis, and regulation of endocytosis and cell polarization. It has been linked to flower formation, tropism, stigma development, and responses to oxidative stress, cation stress, and boron levels. Associations with traits include gravity response, phototropism, shoot growth angle, leaf vein morphology, seed set, root length, and sensitivity to blue light, ethylene, and herbicides. Studies of related genes in other species connect the family to plant height, tillering, root architecture, aluminium tolerance, and chilling stress.
