ARF — Pisum sativum

Summary

PsARF (PSAT1G058240) on garden pea chromosome 1LG6 encodes an ADP-ribosylation factor, a small GTPase of the Arf1-5-like family with GTP binding, GTPase activity, G protein activity, and phospholipase activator activity. It is associated with auxin transport, intracellular protein transport, vesicle transport, and protein transport, and localises to the Golgi complex and cytoplasm. Studies of related genes in other species link the ARF family to traits including auxin content and sensitivity, lateral root and root length, seed size and maturation, starch and protein content, biomass yield, chlorophyll content, nitrate uptake, style length, and responses to salt and drought.
