AGR — Brachypodium distachyon

Summary

BdAGR (BRADI_2G48170V3) in Brachypodium distachyon encodes a member of the auxin efflux carrier family, possessing auxin efflux transmembrane transporter activity and inositol-1,4-bisphosphate 1-phosphatase activity, along with multiple phosphoinositide-binding capabilities. The gene is associated with auxin transport, gravitropism, and responses to abiotic stimuli. It is linked to traits including gravity response, phototropism, root and shoot architecture, leaf and flower morphology, seed set, and sensitivity to hormones and environmental stresses. Studies of related genes in other species connect the family to plant height, tillering, root system architecture, pollen development, and tolerance to aluminium and chilling stress. The protein localizes to the basal plasma membrane, recycling endosome, and auxin efflux carrier complex, and is associated with regulation of endocytosis, cell polarization, and phragmoplast microtubule organization.
