ARF — Medicago truncatula

Summary

MTR_2G022200, also known as MtGB1 or ARF, encodes a small GTPase of the ARF/SAR family with GTP binding, GTPase activity, phospholipase activator activity, and G protein activity. In barrel medic, this gene is associated with organogenesis, lateral root development and formation, root development, geotropism, auxin signaling, nodulation, cell division, post-embryonic development, intracellular protein transport, vesicle transport, and protein breakdown. The encoded protein localizes to the Golgi membrane, Golgi complex, cytoplasm, nucleus, microtubule organizing center, and spindle. Associations with lateral root length and root length have also been recorded. Studies of related genes in other species link the family to root mass density and root morphology traits.
