ARA7 — Brassica oleracea var. botrytis

Summary

BoARA7 (symbol ARA7) on cauliflower chromosome 9 encodes a small GTPase with GTPase activity, GTP binding, and protein binding functions, belonging to the small GTP-binding protein family. This gene is associated with multiple vesicle trafficking processes, including endocytosis, vacuolar transport, protein secretion, and cell plate assembly, as well as late endosome-to-vacuole transport and endomembrane organization. It localizes to endosomes, the tonoplast, Golgi membrane, and protein storage vacuole membrane. BoARA7 is linked to root development traits, auxin content, embryo development, salt tolerance, disease tolerance, and leaf senescence. Associations with root gravitropism, lateral root formation, silique development, guard cell development, and myrosin cell development have been noted. Related genes in other species are linked to vacuolar trafficking, root circumnutation, disease resistance, and pollen tube growth.
