CRC — Brassica oleracea var. botrytis

Summary

BoCRC, located on chromosome 8 of cauliflower (Brassica oleracea var. botrytis), encodes a seed storage protein belonging to the 11S globulin (cupin) family, with nutrient reservoir activity and binding capabilities for IgG, IgE, and phosphorylated amino acids. The gene is associated with seed and embryo development, cotyledon development, fruit development, carpel and nectary formation, photoprotection, and responses to abscisic acid and brassinosteroid signalling. It is linked to the regulation of superoxide release, xanthophyll metabolism, and abscisic acid anabolism. Associations include seed storage protein accumulation, plant growth, and traits such as violaxanthin and neoxanthin content, abscisic acid concentration, and root morphology. The protein localises to the endoplasmic reticulum, endosperm protein body, chloroplast envelope and stroma, plasmodesmata, and other cellular compartments. Related genes in other species are linked to neoxanthin synthesis and abscisic acid biosynthesis.
