ARF — Capsicum annuum

Summary

CaARF (T459_02410) on pepper chromosome 1 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, regulation of auxin metabolism, and blue light signaling. It is linked to traits such as shoot and root phototropism, leaf vein morphology, biomass yield, water use efficiency, days to flowering, ethylene and abscisic acid sensitivity, low temperature and oxidative stress responses, disease tolerance, and phenolic compound content. Localization evidence connects the product to Golgi-associated vesicles, COPII-coated vesicles, the cis-Golgi network, early endosomes, and the ER membrane.
