ARF — Medicago truncatula

Summary

MTR_5G007810 (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, nodulation, geotropism, and root development, including lateral root formation and development. It is linked to lateral root length and root length traits. The encoded protein localises to the Golgi complex and cytoplasm and is connected to vesicle transport, intracellular protein transport, and protein breakdown. Related genes in other species link the family to ADP-ribosylation factor activity (EC 3.6.5.2).
