AGR — Brachypodium distachyon

Summary

BdAGR (BRADI_1G45020V3) on chromosome 1 of Brachypodium distachyon encodes a member of the PIN-like auxin efflux carrier 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 auxin signalling, clathrin-mediated endocytosis, and regulation of endocytosis, cell polarization, and phragmoplast microtubule organization. It has been linked to flower formation, tropism, stigma development, and responses to oxidative stress, cation stress, and boron levels. Associations with traits such as gravity response, phototropism, shoot growth angle, leaf vein morphology, seed set, root length, and sensitivity to blue light, ethylene, and herbicides have been reported. Studies of related genes in other species connect the family to plant height, tillering, root architecture, pollen development, and aluminium tolerance.
