ARF — Cucumis melo

Summary

MELO3C009969.2, designated CmARF on melon chromosome 5, encodes a small GTPase of the Arf1-5-like family. The product is annotated with G protein activity, phosphatidylinositol kinase activity, phospholipase activator activity, and F-actin binding, among many other molecular functions. In melon, CmARF is associated with vesicle-mediated transport to the plasma membrane, ER-to-Golgi transport, Golgi organization, regulation of auxin metabolism, and blue light signaling. It has been linked to a wide range of agronomic traits including biomass yield, water use efficiency, days to flowering, leaf senescence, disease tolerance, low temperature and oxidative stress responses, abscisic acid sensitivity, and root and shoot phototropism. Related genes in other species are associated with fruit set, leaf relative water content, and stress tolerance.
