ARF — Cucumis sativus

Summary

CsARF (CSA_3G837590) encodes a small GTPase of the Arf1-5-like family, possessing G protein activity, phosphatidylinositol kinase activity, phospholipase activator activity, and actin binding. In cucumber, it is associated with vesicle-mediated transport, Golgi organization, ER-to-Golgi transport, phloem transport, and response to brefeldin A. The gene is linked to regulation of auxin metabolism, phototropism, gravitropism, and blue light signaling. Associations with agronomic traits include biomass yield, water use efficiency, days to flowering, root mass density, leaf senescence, disease tolerance, and responses to ethylene, abscisic acid, low temperature, and oxidative stress. It is also connected to leaf vein morphology, stomatal resistance, and viral disease response. Studies of related genes in other species link the family to fruit set, leaf relative water content, nitrogen content, and abiotic stress responses.
