ARF — Cucumis melo

Summary

MELO3C021556.2, designated CmARF on melon chromosome 10, encodes a small GTPase of the Arf1-5-like family. The product possesses G protein activity, phosphatidylinositol kinase activity, phospholipase activator activity, and actin binding. In melon, CmARF is associated with vesicle-mediated transport, Golgi organization, protein retention in the ER lumen, regulation of auxin metabolism, and phloem transport. It localizes to Golgi-associated vesicles, COPII-coated vesicles, the cis-Golgi network, and the ER membrane. The gene is linked to biomass yield, water use efficiency, days to flowering, root mass density, leaf senescence, disease tolerance, and responses to low temperature, oxidative stress, and salinity. Associations also connect CmARF to phototropism, blue light sensitivity, leaf vein morphology, and viral disease response.
