CRB — Brassica napus

Summary

BnCRB (CRB) on chromosome A10 of oilseed rape (Brassica napus) encodes a seed storage protein of the 11S globulin (cruciferin) family, containing cupin domains and annotated with nutrient reservoir activity, IgG binding, and IgE binding. The gene is associated with seed development, seed germination, lipid storage, protein homotrimerization, syngamy, digestion, cellular response to abscisic acid, defense response, and carbohydrate metabolism. It localizes to the rough endoplasmic reticulum and extraorganismal space. Traits linked to CRB include heterosis, protein content, and seed viability, with a phenotype of seed storage protein accumulation. Studies of related genes in other species connect the family to seed protein content, amino acid content, seed maturation, seed longevity, drought tolerance, and salt response.
