ARF — Cucumis melo

Summary

MELO3C005422.2, designated CmARF on melon chromosome 10, encodes a small GTPase of the Arf1-5-like family with GTPase, GTP-binding, protein kinase, and blue light photoreceptor activities, and is annotated for phospholipase activator and FMN-binding functions. The gene is associated with fruit development, auxin signaling, circadian rhythm, chloroplast accumulation movement, blue light signaling, intracellular protein transport, and regulation of proton transport and stomatal movement. It localizes to the cytoplasm, nucleus, Golgi, plant-type vacuole, and plasma membrane. CmARF is linked to traits including phototropism, blue light sensitivity, biomass yield, water use efficiency, ethylene sensitivity, leaf senescence, root morphology, days to flowering, phenolic compound content, viral disease response, and low temperature stress response. Related genes in other species are associated with chloroplast relocation, stomatal aperture opening, guard cell anion channel regulation, and lateral root growth.
