Fig. 2: Structure of pericentromeric regions and distribution of centromeric satellite subtypes.
From: Telomere-to-telomere genome assembly of the Dipteran Bactrocera dorsalis from a single individual
a Pericentromeric regions visualized by StainedGlass. The locations of the gene models, three types of centromeric satellites, and reverse transcriptase are indicated by purple bars. b Subtypes of centromeric satellite monomers. The upper plot shows the coefficient of variation of the sequence divergence rate for the BdoSat consensus, as annotated by RepeatMasker in hifiasm unitigs. The x-axis represents the average identity to the BdoSat monomer consensus for each unit. The lower plot shows the identity distribution of the BdoSat monomer consensus in the final T2T assembly. Annotations with lengths less than 95% of the consensus length were filtered from the RepeatMasker output. c Phylogenetic relationships of subtypes within BdoSat2 and BodSat3. d FISH analysis of the centromeric region of the chromosome, showing the most abundant subtype for each BdoSat. Images shown are representative of at least three independent experiments.
