ARF — Medicago truncatula

Summary

MTR_5G034130 (symbol ARF) 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, nodulation, root development, lateral root formation and development, geotropism, post-embryonic development, protein breakdown, intracellular protein transport, and vesicle transport. The gene is linked to lateral root length and root length. The encoded protein localises to the Golgi complex and cytoplasm. Studies of related genes in other species connect the family to auxin content and salt tolerance.
