DNA regions homologous to the TRGF containing Dsim_GD19764 and Dsec_GM10790. Homologous protein-coding genes are the same color (each element corresponds to an exon), small nuclear RNA (snRNA) genes are white. The direction of the arrow shows which strand the gene is located on. Features with dashed outlines are not annotated. The diagram is not to scale. In the order from top to bottom, the orange genes are Dsim_GD29138, Dsec_GM10660, Dmel_CG12589, Dyak_GE25310, Dere_GG11200 (with a syntenic homolog Dana_GF16073 in Drosophila ananassae); the yellow genes are Dsim_GD19763, Dsec_GM10789, Dmel_CG12590, Dyak_GE25451, Dere_GG12627 (with syntenic homologs Dana_GF18925 and Dpse_GA11706 in D. ananassae and D. pseudoobscura, respectively); the blue genes are Dsim_GD19765, Dsec_GM10791, Dmel_CG12591, Dyak_GE25452, Dere_GG12638 (with syntenic homologs Dana_GF18926 and Dpse_GA11707 in D. ananassae and D. pseudoobscura, respectively); the purple genes are Dsim_GD19639, Dsec_GM10658, Dmel_CG12161, Dyak_GE25306, Dere_GG11178.
