ARF — Cucumis sativus

Summary

CsARF (CSA_5G601490) on cucumber chromosome 5 encodes an ADP-ribosylation factor, a member of the Arf1-5-like small GTPase family. The protein exhibits GTPase activity, GTP binding, G protein activity, phospholipase activator activity, and metal binding. It is associated with intracellular signal transduction, protein transport, vesicle transport, auxin signaling, positive gravitropism, morphogenesis, response to cold, and virus-induced PTGS. The gene product localizes to the Golgi complex and cytoplasm. CsARF is also linked to ethylene sensitivity. Studies of related genes in other species connect the ARF family to traits including leaf relative water content, leaf angle, fruit firmness, starch content, stem elongation, fruit size, leaf shape, sugar content, stomatal resistance, organ identity, root length, chlorophyll content, and plant height.
