[R1 and R2 retrotransposons of German cockroach Blattella germanica: comparative analysis of 5' truncated copies integrated into genome].
This is the first report providing results on identification, cloning, and sequencing of extended fragments (5'-truncated copies) of R1 and R2 retrotransposons integrated into Blattella germanica genome. Comparative structural analysis of the received clones revealed two distinct subfamilies of R1 elements. However, all B. germanica R1 clones have two common features: poly(T) tails and similar target site duplications. Nucleotide structure and organization of five sequenced R2 fragments was similar. Analysis of R2 nucleotide sequences revealed typical deletions at the 3'end of target sites and lack of homopolynucleotides tails.
