ARF — Brachypodium distachyon

Summary

BdARF (BRADI_2G53076V3) on chromosome 2 of Brachypodium distachyon encodes a small GTPase of the Arf1-5-like family with GTP binding, GTPase activity, phospholipase activator activity, and G protein activity. The protein localises to the Golgi complex and cytoplasm and is associated with intracellular protein transport, vesicle transport, and signal transduction. In this species, BdARF is linked to IAA content and root length. Studies of related genes in other species connect the family to a wide range of agronomic traits, including grain yield, grain weight, grain size, grain number, seed size, seed germination, spikelet number, tiller number, tiller angle, plant height, anthesis time, root number, lateral root number, chlorophyll content, starch content, protein content, soluble protein content, auxin content, auxin sensitivity, callus induction, salinity tolerance, cold tolerance, drought tolerance, and stripe rust resistance.
