ARF1 — Medicago truncatula

Summary

MTR_4G128910, also known as MtARF3, MtARF1, or MtARL1, encodes a small GTPase of the ARF/SAR family with GTPase, GTP binding, and phospholipase activator activities. This barrel medic gene is associated with auxin signaling, organogenesis, nodulation, and root and lateral root development, as well as leaf shape, root length, and lateral root length. The encoded protein localizes to the Golgi stack, trans-Golgi network, and plasma membrane, and is linked to Golgi vesicle transport and intracellular protein transport. Related genes in other species link the family to leaf adaxial-abaxial polarity, floral meristem determinacy, anther morphogenesis, somatic embryogenesis, Golgi targeting, and plant development.
