Overview over analyzed genome sequences and their taxonomic classification. The names of 62 non-mammalian species whose genomes we analyzed are grouped by phylum. 11 additional mammalian genomes we analyzed are summarized as "11 Mammals". Next to each species, the number of BEL/Pao elements we identified is shown. If we were not able to identify any element in one genome, the genome name is shown in red. Genome sequences where BEL/Pao elements had been already identified previously are marked with an asterix (*). For completeness we list seven additional species where no complete genome sequence was available but where BEL/Pao elements had been identified previously (shown in parentheses). A: Abe et al.
