Domain organization of the ORF2 C-terminal region of the German cockroach retroposon R1

Domain organization of the ORF2 C-terminal region of the German cockroach retroposon R1 Using cosmid vector, a gene library of German cockroach Blattella germanica was constructed. From this library, clones containing full-length copies of two subfamilies of R1 retroposons were selected. Retroposons R1 of German cockroach belonging to different subfamilies were shown to be different in domain organization of the ORF2 C-terminal region. For the first time, retroposons transmembrane domains were identified in the sequences of R1. It was demonstrated that two retroposon R1 subfamilies of German cockroach arose as a result of intragenomic divergence rather than via horizontal transfer of alien mobile element into cockroach genome. The differences in domain organization appeared not as a result of saltatory recombination processes, but as a consequence of gradual mutation accumulation, which led to either degeneration, or to domain formation. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Genetics Springer Journals

Abstract

Using cosmid vector, a gene library of German cockroach Blattella germanica was constructed. From this library, clones containing full-length copies of two subfamilies of R1 retroposons were selected. Retroposons R1 of German cockroach belonging to different subfamilies were shown to be different in domain organization of the ORF2 C-terminal region. For the first time, retroposons transmembrane domains were identified in the sequences of R1. It was demonstrated that two retroposon R1 subfamilies of German cockroach arose as a result of intragenomic divergence rather than via horizontal transfer of alien mobile element into cockroach genome. The differences in domain organization appeared not as a result of saltatory recombination processes, but as a consequence of gradual mutation accumulation, which led to either degeneration, or to domain formation.
