Genomic Structures of E(spl) complexes from Hymenoptera. Schematic phylogeny of Hymenoptera with structures of E(spl)-C from examined species. Colour coding of bHLH genes follows Fig. 1 (bHLH-1, light blue; bHLH2, Dark blue; her, green). Red hexagons indicate mα, genes. White ovals indicate inserted genes with no homology to bHLHO or mα, brown ovals represent Tubulin Tyrosine ligase genes. Purple circles mark gooseberry genes. Where the colour of a bHLH gene is lighter, identification of this gene is only through placement in the complex due to gaps in the genome sequence. Arrows indicate direction of transcription
