CRB — Brassica oleracea

Summary

BoCRB (CRB, CRU2) on cabbage chromosome 5 encodes a seed storage protein of the 11S globulin (cruciferin) family, possessing nutrient reservoir activity and annotated with IgG and IgE binding. The gene is associated with seed development, seed germination, protein homotrimerization, systemic acquired resistance, and cellular response to abscisic acid stimulus. Its product localises to the rough endoplasmic reticulum and extraorganismal space. BoCRB is associated with seed storage protein accumulation. Studies of related genes in other species connect this family to seed protein content, amino acid content, seed viability, seed longevity, seed maturation, heterosis, drought tolerance, and salt response.
