CRB — Cucumis melo

Summary

MELO3C012887.2, designated CmCRB on melon chromosome 5, encodes a protein with 11S seed storage, cupin, and RmlC-like jellyroll domains, and is annotated with nutrient reservoir activity, IgG/IgE binding, metal binding, and ATP binding. In melon, this gene is associated with a wide range of developmental and metabolic processes, including seed, fruit, flower, and cotyledon development, fruit ripening, seed germination, abscission, sex determination, carpel and stamen development, photoprotection, xanthophyll metabolism, abscisic acid and ethylene anabolism, and regulation of superoxide release. It is linked to traits such as violaxanthin and neoxanthin content, abscisic acid concentration, photosynthetic rate, floral organ identity, and root morphology. The protein localizes to the endosperm protein body, protein storage vacuole, chloroplast envelope, and ER. Studies of related genes in other species connect the family to seed protein content, amino acid content, and stress responses.
