Comparative genomics of the dactynotine sub-tribe. a Maximum likelihood phylogeny of dactynotine aphids based on a concatenated alignment of 5091 conserved single-copy protein coding genes. We included seven outgroup aphid species from Aphidinae but for simplicity only show M. persicae. The full phylogeny is shown in Additional File 2: Figure S11. All branches received maximal support according to the Shimodaira-Hasegawa test [52] implemented in FastTree [53, 54] with 1000 resamples. Branch lengths are in amino acid substitutions per site. The tree is annotated with genome assembly length and gene counts coloured by orthology relationships across the full phylogeny. b Chromosome evolution in the dactynotine sub-tribe. Plot shows blocks of syntenic genes identified between S. miscanthi (top), A. pisum (middle) and M. persicae (bottom) chromosomes. Chromosomes containing black arrows are visualised as the reverse compliment to aid clarity. Ap1 and Mp1 in A. pisum and M. persicae, respectively, have previously been identified as the X (sex) chromosome and are homologous to Sm1 (scaffold_1) in our new S. miscanthi (Simis_v2) genome assembly
