ARF — Medicago truncatula

Summary

MTR_5G016540 (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. The gene is associated with auxin signaling, organogenesis, lateral root development and formation, root development, geotropism, nodulation, post-embryonic development, protein breakdown, intracellular protein transport, vesicle transport, and protein transport. It 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.
