ARF — Pisum sativum

Summary

PsARL5 (PSAT6G114000, also known as ARF, ARL5, or MTV8) on garden pea chromosome 6LG2 encodes an ADP-ribosylation factor-like protein 5, a member of the small GTPase ARF/SAR family with GTPase activity, GTP binding, G protein activity, phospholipase activator activity, and metal binding. The gene is associated with auxin transport, intracellular protein transport, vesicle transport, and protein transport, and its product localizes to the Golgi complex, plasmalemma, and cytoplasm. Studies of related genes in other species link the family to auxin content, lateral root length, root length, and salt tolerance, though these associations are not yet established in pea.
