CRB — Cucumis melo

Summary

MELO3C024414.2, designated CmCRB on melon chromosome 2, encodes a member of the 11S seed storage globulin family (Cupin 1 superfamily) with nutrient reservoir activity and IgG/IgE binding capacity. The gene is associated with seed development, germination, embryo development ending in seed dormancy, and seed storage protein accumulation. It is linked to fruit development and ripening, flower development, sex determination, carpel and stamen development, and abscission. Associations also include abscisic acid anabolism and concentration, ethylene anabolism, brassinosteroid-mediated signalling, xanthophyll metabolism, photoprotection, and regulation of superoxide release. The product localises to the endosperm protein body, vacuole, chloroplast envelope and stroma, LHCII, plasmodesmata, and extracellular space. Related genes in other species link the family to neoxanthin biosynthesis, temperature stress response, and parthenocarpy.
