ARA7 — Brassica oleracea var. botrytis

Summary

BoARA7 (symbol ARA7) on cauliflower chromosome 7 encodes a small GTPase with GTPase activity, GTP binding, and protein binding functions. It is associated with endocytosis, vacuolar transport, protein secretion, cell wall biogenesis, and late endosome-to-vacuole transport. The gene has been linked to auxin content, root development, embryo development, disease tolerance, and salt tolerance. Phenotypic associations include root gravitropism, lateral root development, guard cell development, silique development, auxin response, and receptor endocytosis. Localization evidence connects the product to endosomes, vacuolar membranes, Golgi membranes, and the endoplasmic reticulum. Studies of related genes in other species link the family to vacuolar trafficking, disease resistance, pollen tube growth, and root circumnutation.
