CRA1 — Brassica napus

Summary

BnCRA1 (CRA1) on chromosome A02 of oilseed rape encodes a protein belonging to the cupin superfamily and possessing nutrient reservoir activity, IgG and IgE binding, metal binding, and protein binding functions. The gene is associated with seed development, cotyledon development, embryogenesis, seedling development, protein homotrimerization and hexamerization, digestion, cellular response to abscisic acid, and NO storage. It localizes to the rough endoplasmic reticulum, extraorganismal space, and nucleus. BnCRA1 is linked to heterosis, protein content, seed storage protein accumulation, and growth and biomass allocation. Studies of related genes in other species connect the family to seed protein content, amino acid content, seed longevity, viability, weight, size, dormancy, maturation, oleic acid content, leaf number, root morphology, and responses to salt, drought, and oxidative stress.
