ARF — Solanum tuberosum

Summary

PGSC0003DMG400004691, designated StARF on potato chromosome 12, encodes a small GTPase of the Arf1-5-like family. The gene is associated with diverse molecular functions including G protein activity, phosphatidylinositol kinase activity, phospholipase activator activity, actin binding, histone acetyltransferase activity, blue light photoreceptor activity, and FMN binding. It has been linked to biological processes such as vesicle-mediated transport to the plasma membrane, ER-to-Golgi transport, Golgi organization, regulation of auxin metabolism, chloroplast accumulation movement, blue light signaling, and anthocyanin biosynthesis. Localization evidence connects the product to Golgi-associated vesicles, COPII-coated vesicles, the cis-Golgi network, early endosomes, and the ER membrane. Associations with agronomically relevant traits include biomass yield, water use efficiency, chlorophyll content, disease tolerance, salt tolerance, root mass density, days to flowering, leaf senescence, and responses to light intensity, low temperature, oxidative stress, and ethylene.
