ARF — Cucumis melo

Summary

MELO3C028584.2, designated CmARF on melon chromosome 2, encodes a member of the small GTPase ARF/SAR family, a P-loop NTPase. The gene is associated with vesicle-mediated transport, including ER-to-Golgi and Golgi organization, as well as regulation of auxin metabolism, blue light signaling, and chloroplast accumulation movement. It has been linked to traits such as phototropism, leaf vein morphology, biomass yield, water use efficiency, days to flowering, root mass density, and responses to ethylene, abscisic acid, low temperature, oxidative stress, and viral disease. Localization evidence connects the product to Golgi-associated vesicles, COPII-coated vesicles, the ER membrane, and the trans-Golgi network. Studies of related genes in other species link the ARF family to fruit set, leaf relative water content, and abiotic stress responses.
