ARF — Capsicum annuum

Summary

CaARF (T459_17936) on pepper chromosome 6 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 G protein and phospholipase activator functions. The gene is associated with fruit development and ripening, seed and leaf development, auxin signaling, circadian rhythm, and regulation of stomatal movement and proton transport. It localizes to the cytoplasm, nucleus, Golgi, vacuole, and plasma membrane. Associations include shoot and root phototropism, blue light sensitivity, biomass yield, water use efficiency, viral disease response, phenolic compound content, leaf size and senescence, ethylene sensitivity, and root and hypocotyl morphology traits. Related genes in other species are linked to chloroplast relocation, phototropic growth, guard cell anion channel regulation, and lateral root growth.
