ARF — Cucumis sativus

Summary

CSA_7G414405, designated ARF, encodes a small GTPase of the Arf1-5-like family with GTPase activity, GTP binding, G protein activity, phospholipase activator activity, and metal binding. In cucumber, this gene is associated with pigmentation, fruit development, auxin and ABA signaling, intracellular signal transduction, protein and vesicle transport, virus-induced PTGS, and response to cold. It localizes to the Golgi complex and cytoplasm. The gene is linked to cell growth and development traits and quantum yield. Studies of related ADP-ribosylation factor genes in other species connect the family to similar transport and signaling roles, though these functions are not yet established in cucumber.
