ARF — Cucumis melo

Summary

MELO3C009966.2, designated CmARF on melon chromosome 5, encodes a small GTPase of the Arf1-5-like family. The product is associated with diverse molecular functions including G protein activity, phosphatidylinositol kinase activity, phospholipase activator activity, F-actin and G-actin binding, histone acetyltransferase activity, FMN binding, double-stranded methylated DNA binding, and blue light photoreceptor activity. It localises to Golgi-associated vesicles, COPII-coated vesicles, the cis-Golgi network, early endosomes, the trans-Golgi network, and the ER membrane. CmARF is linked to vesicle-mediated transport to the plasma membrane, protein retention in the ER lumen, Golgi organisation, clathrin-mediated endocytosis, ER-to-Golgi transport, chloroplast accumulation movement, blue light signalling, phloem transport, leaf vascular tissue pattern formation, and regulation of auxin metabolism. Associations with agronomic traits include biomass yield, water use efficiency, days to flowering, root mass density, stomatal resistance, leaf senescence, ethylene sensitivity, abscisic acid sensitivity, oxidative stress response, low temperature stress response, disease tolerance, and viral disease response.
