Sequence composition of satellite units within and across pericentromeric MaSat arrays. Alignments of A the MaSat consensus with repeat units from four representative MaSat homogeneous arrays, and B the MaSat consensus sequences with repeat units from four representative divergent arrays. Reference satellite consensus sequences used for the alignments are as described previously [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 3: Fig S3. 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 homogeneous and divergent MaSats. D The distribution of different types of MaSat arrays. Phylogenetic trees illustrating the relationships among all satellite units within a given array are provided below each alignment
