Genome clustering of eight CSEP paralogs from family 7 on two sequence scaffolds. A: Correlations between the phylogenetic relationships based on nucleotide sequences of CSEP paralogs from family 7 and their locations on the genomic sequence scaffolds 005496 (red) and 005502 (blue) indicated with dotted lines. Only the relevant parts of the sequence scaffolds (scale bar) are shown. The colour code of the CSEPs refers to the genomic organization shown in panel B. B: Schematic illustration of the genomic organization (encompassing about 5 kb) of the eight CSEP paralogs with the retro-transposable elements Egh24 and Eg-R1[15, 16]. The percentages of nucleotide sequence identity in pairwise comparisons are indicated and abrupt changes in sequence similarity are indicated with vertical dashed lines in red. The colour code of the CSEPs refers to the phylogenetic tree shown in panel A. Scale bars represent lenghts of DNA in base pairs.
