ARF — Capsicum annuum

Summary

CaARF (T459_09763) on pepper chromosome 3 encodes a small GTPase of the Arf1-5-like family with GTPase, GTP-binding, protein kinase, and blue light photoreceptor activities, and is associated with G protein and phospholipase activator functions. The gene is linked to 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, and plasma membrane. Associations include phototropism, blue light sensitivity, water use efficiency, biomass yield, root and shoot traits, ethylene sensitivity, viral disease response, phenolic compound content, and low temperature stress response. Studies of related genes in other species connect the family to chloroplast relocation, phototropic growth, guard cell anion channel regulation, and lateral root growth.
