ARF — Medicago truncatula

Summary

MTR_1G076550, designated MtARL5 (also known as ARF, MtARFC1, or MTV8) on barrel medic chromosome 1, encodes a small GTPase of the ARF/SAR family with GTP binding and GTPase activity, as well as G protein and phospholipase activator activity. The gene is associated with organogenesis, lateral root development and formation, root development, geotropism, nodulation, auxin signaling, vesicle and intracellular protein transport, protein breakdown, and post-embryonic development. Its product localizes to the Golgi complex, plasmalemma, and cytoplasm. MtARL5 is linked to lateral root length and root length. Related genes in other species connect the family to auxin content and salt tolerance.
