ARF — Nicotiana attenuata

Summary

A4A49_55922 (ARF) in coyote tobacco (Nicotiana attenuata) encodes a small GTPase of the Arf1-5-like family, with annotated molecular functions including G protein activity, phosphatidylinositol kinase activity, phospholipase activator activity, and actin binding. The gene is associated with vesicle-mediated transport to the plasma membrane, ER-to-Golgi transport, Golgi organization, and protein retention in the ER lumen. It is linked to nicotine and alkaloid anabolism, anthocyanin anabolism, regulation of auxin metabolism, and blue light signaling. Associations with traits include biomass yield, water use efficiency, days to flowering, leaf senescence, stomatal resistance, root mass density, lateral root length, and responses to low temperature, oxidative stress, ethylene, and abscisic acid. The gene is also linked to phototropism, chloroplast accumulation movement, and viral disease response.
