Sequence composition of satellite units within and across centromeric MiSat arrays. Alignment of A the MiSat reference sequence with repeat units from representative MiSat arrays and B the 112-mer and 112–64-dimer MiSat consensus with repeat units from representative variant MiSat arrays. Reference satellite consensus sequences used for the alignments are as described previously [47, 48, 51]. The length of each array is given, and the X-axis is not to the scale. All subunits are arranged in the order they appear, spanning from the beginning to the end of a given array. The alignment of all ordered repeat units with the reference consensus is performed for the entire array. Alignments of repeat units from the beginning of a given array are shown, and alignments for the whole of the arrays are provided in Additional file 2: Fig S2. Neighbor-joining phylogenetic trees illustrating the relationships among all satellite units within a given array are presented below each alignment. C The phylogenetic relationship between different classes of MiSats. D The distribution of different types of MiSat arrays
