SOXE group gene duplication in hymenoptera. A. Illustration of the SoxE gene genomic region from A. mellifera and N. vitripennis genomes. Both genomes encode two copies of SoxE group gene that share a common promoter region. B. Insect SOXE group proteins form a separate clade to the vertebrate SOXE proteins, that are split into three separate groupings, SOX8, SOX9 and SOX10. Insect SOXE proteins are most closely related to vertebrate SOX8 proteins. The unrooted tree was constructed using Phylip, bootstrap values are shown at internal branches.
