Extended Data Fig. 6: Structural variations in centromere regions.

a, Schematic diagram of structural variations in satellite arrays (SaSVs). A query satellite array is aligned against a reference array using satellites and TEs as markers. Based on syntenic pairing of CEN155 satellites and TEs, SVs with more than 50 copies of CEN155 satellites are defined as large expansions (LEs) or contractions (LCs). Regions with continuously poor synteny are referred to as divergent blocks, compared to the reference array. b, SaSV number and involved CEN155 satellite size (upper), and SaSV size distribution (bottom) in GJ and XI satellite arrays compared to their corresponding reference assemblies NIP and NJ11, respectively. c. SaSVs in individual genomes associated with the phylogenetic kinship.
