TEs components of H. alpinum pericentromeres and their relationships with satDNAs. A The frequency of the major TE family in the conversion to hits/10Mbp (Z axis) in subsets of the ONT library shows a significant copy-number reduction, except for Tekay and CRM in pericentromeres (see also Table 3). B Example of the intermixing of satDNAs and TEs in the longest read of the p-subset. C Insertion of the Tekay element between two arrays of HintCl-18 satDNA (read 4772). D Insertion of the CRM element in the array of HintCl-18 satDNA (read 1047). E Localization of the RT (red) and PROT (green) conserved domains of the Tekay element between arrays of Halp-aLTR-1 (blue) (read 1819). F Location of the conserved RT domain (red) of the Tekay element between arrays of Halp-aLTR-2 (blue) (read 1719). G Alignment of the Angela GAG CD and HintCl-18 monomer. H TE-like structure of HintCl-18 satDNA arrays. I Comparison of the LTRs structure via dot-plots of two present and two ancient Tekay elements. J Dendrogram of LTR sequences
