ARF — Medicago truncatula

Summary

MTR_5G034125 (symbol ARF) on barrel medic chromosome 5 encodes a small GTPase of the Arf1-5-like family, with GTPase activity, GTP binding, G protein activity and phospholipase activator activity. It is associated with auxin signaling, organogenesis, post-embryonic development, nodulation, root development, lateral root development and formation, geotropism, protein transport, vesicle transport, intracellular protein transport, and protein breakdown. The gene product localises to the Golgi complex and cytoplasm. It is linked to lateral root length and root length. Studies of related genes in other species connect the family to auxin content and salt tolerance.
