Functional category of the shared proteins identified (core proteome) across embryogenesis of honey bee workers (A.m.ligustica) at 24 h, 48 h, and 72 h. Proteins are classified based on the biological process of gene ontology (GO) using Blast2GO (36). Because proteins usually perform multiple fuctions, a protein may be classified into multiple categories. The percentage of each functional group is obtained on the basis of the number of proteins under each of the functional groups divided by the total number of shared proteins. Color codes represent different protein functional groups.
