ARF — Medicago truncatula

Summary

MTR_6G005820, designated MtARF, encodes a small GTPase of the Arf1-5-like family with GTPase activity, GTP binding, G protein activity and phospholipase activator activity. It is associated with auxin signaling, organogenesis, lateral root development and formation, root development, geotropism, nodulation, post-embryonic development, intracellular protein transport, vesicle transport, and protein breakdown. The product localises to the Golgi complex and cytoplasm. Annotated associations link MtARF to lateral root length and root length. Studies of related genes in other species connect the ARF family to traits including drought tolerance, salt response, auxin content and sensitivity, nitrate uptake, biomass yield, starch and protein content, seed size and maturation, chlorophyll content, and style length.
