ARF — Medicago truncatula

Summary

MTR_1G086480, also known as ARF, is located on chromosome 1 of barrel medic (Medicago truncatula) and encodes a small GTPase of the Arf1-5-like family, possessing GTPase activity, GTP binding, G protein activity, and phospholipase activator activity. The gene is associated with organogenesis, lateral root development and formation, root development, post-embryonic development, geotropism, nodulation, auxin signaling, intracellular protein transport, vesicle transport, and protein breakdown. Its product localizes to the Golgi complex and cytoplasm. The gene 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.
