ARF — Capsicum annuum

Summary

CaARF (T459_21161) on pepper chromosome 8 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, ER-to-Golgi transport, Golgi organization, and regulation of auxin metabolism. It has been linked to numerous agronomically relevant traits, including biomass yield, water use efficiency, days to flowering, root mass density, stomatal resistance, leaf senescence, low temperature and oxidative stress responses, abscisic acid sensitivity, disease tolerance, and viral disease response. Additional associations include phototropism, blue light sensitivity, leaf vein morphology, phenolic compound content, and ethylene sensitivity. Related genes in other species are linked to fruit set, fruit firmness, starch content, and stress tolerance.
