ARA7 — Brassica oleracea var. botrytis

Summary

BoARA7 (BOLND125_C07P026440.1) on cauliflower chromosome 7 encodes a small GTPase, possessing GTPase activity, GTP binding, and protein binding functions. This gene is associated with endocytosis, vacuolar transport, protein secretion, cell plate assembly, and endomembrane organization. It is linked to leaf senescence, programmed cell death, post-embryonic root development, and cell wall biogenesis. Localization evidence connects the product to endosomes, the tonoplast, Golgi membrane, and protein storage vacuole membrane. Associations with agronomically relevant traits include auxin content, root development, disease tolerance, and salt tolerance. Phenotypic connections involve root gravitropism, lateral root formation, guard cell development, silique development, and primary root elongation. Related genes in other species link the family to vacuolar trafficking, disease resistance, pollen tube growth, and dwarfism.
