Phylogeny and genomic organisation of Drosophila runt domain protein sequences.

An unrooted Bayesian phylogeny of Drosophila full-length RD protein sequences. Phylogeny was constructed using MrBayes [67] under the Jones amino acid substitution model. Posterior probabilities are shown on internal branches. The RD proteins are subdivided into the four established orthologue groups. Species names are abbreviated as follows: Dmel = D. melanogaster, Dsim = D. simulans, Dsec = D. sechellia, Dyak = D. yakuba, Dere = D. erecta, Dana = D. ananassae, Dpse = D. pseudoobscura, Dper = D. persimilis, Dwil = D. wilistoni, Dmoj = D. mojavensis, Dvir = D. virilis, Dgri = D. grimshawi and species names are followed by the FlyBase accession numbers. Asterisks indicate protein sequences that have been manually annotated. Orthologue groups are colour coded, the red group shows homology to the Drosophila runt protein, the purple to the Drosophila lozenge protein, the green to the Drosophila CG42267 protein and the blue to the Drosophila CG34145 protein.
