ARF — Capsicum annuum

Summary

CaARF (T459_33108) on pepper chromosome PGAv.1.6.scaffold1076 encodes an ADP-ribosylation factor (ARF) of the Arf1-5-like small GTPase family. The gene is associated with a broad range of molecular functions including G protein activity, phosphatidylinositol kinase activity, phospholipase activator activity, actin binding, histone acetyltransferase activity, and blue light photoreceptor activity. It is linked to vesicle-mediated transport to the plasma membrane, ER-to-Golgi transport, Golgi organization, chloroplast accumulation movement, blue light signaling, and regulation of auxin and sucrose metabolism. Associations with agronomic traits include biomass yield, water use efficiency, days to flowering, disease tolerance, oxidative and low-temperature stress responses, leaf senescence, root and shoot phototropism, and stomatal resistance. Studies of related genes in other species connect the ARF family to fruit set, tuber sprouting, salt and drought tolerance, and Phytophthora resistance.
