Satellite DNA analysis in ananassae subgroup. A Principal coordinate analysis (PCoA) plot on multiple sequence alignments for satellite array consensus sequences. Each point represents an array with its shape according to the scaffold/Muller element it is located on, colored by species, and its size representing the number of repeats in the array. Colored squares define three groups of Satellite DNA: red square for group 1; blue squares for groups 2 and 3. B Length distribution of satellite DNA repeat monomers in PCoA groups 1–3. Bar colors represent species as depicted in A. C Sequence (bp) proportion of satellite DNA from PCoA group 1 and combined PCoA groups 2 and 3 in the heterochromatic (dark) and euchromatic (light) compartments as defined by TE density (see Methods). D Distribution of PCoA group 1 satellite DNA (red), combined PCoA groups 2 and 3 satellite DNA (blue), TEs (black), and gene exons (yellow) across the chromosomes of the species in the ananassae subgroup. Bins of 100 kb were used for TEs and exons, while 30-kb bins were used for satellite DNA
