ARF — Medicago truncatula

Summary

MTR_5G007820 (ARF) on barrel medic chromosome 5 encodes a small GTPase of the ARF/SAR family, with GTPase activity, GTP binding, G protein activity and phospholipase activator activity. It is associated with auxin signaling, organogenesis, post-embryonic development, root development, lateral root formation and development, geotropism, nodulation, protein breakdown, intracellular protein transport and vesicle transport. The gene product localises to the Golgi complex and cytoplasm. ARF is also linked to lateral root length and root length. Studies of related genes in other species connect the family to similar vesicle trafficking and developmental processes.
