Transposable elements (TEs) are selfish genetic elements whose self‐replication is contrasted by the host genome. In this context, host reproductive strategies are predicted to impact on both TEs load and activity. The presence and insertion distribution of the non‐LTR retrotransposon R2 was here studied in populations of the strictly bisexual Bacillus grandii maretimi and of the obligatory parthenogenetic...
The 28S rRNA genes of several metazoans are interrupted by site-specific targeting non-LTR retrotransposons, such as R2. R2 elements have been deeply analyzed but aspects of their retrotransposition mechanism and the origin of the wide diversity observed are still debated. We characterized six new R2 lineages in four tadpole shrimp species (Notostraca), samples deriving from a parthenogenetic population...
