A proteomic approach for studying LTR retrotransposon host factors in saccharomyces cerevisae
The Ty retrotransposons of S. cerevisiae are mobile elements that resemble retroviruses, both in their genetic structures and replication cycles. Ty retrotransposition begins in the nucleus with the transcription of Ty RNA. Following translation of Ty proteins, virus-like particles (VLPs) assemble …

The contribution of repeat associated small RNAs to genetic variation, hybrid vigor and inbreeding depression in maize
… of a number of distinct long terminal repeat (LTR)-retrotransposon families. These 21-22-nt siRNAs differentially accumulate between B73 and Mo17 as well as their hybrid. </p> <p> We extended this analysis of sRNA families to 36 diverse inbred lines. We found that high copy number families …

The study of ancient viral class II envelope fusion proteins within the viral retroelements of Nematoda and the nuclear plasmids of Dictyostelium
… ceylanicum, a nearly 20 million-year-old Bel/Pao LTR-retrotransposon encodes an ancient viral class II envelope fusion protein. Typically, retroviruses and related degenerate retrotransposons encode a hemagglutinin-like class I envelope fusion protein. A subset of Bel/Pao LTR-retrotransposons …

Characterization and Engineering of Transposons for Genome Editing
… Next, we engineer a non-long terminal repeat (LTR) retrotransposon, R2 from the silkworm Bombyx mori (R2bm), as a site-specific DNA insertion tool in human cells. We show that R2bm can be used to perform DNA insertion into human 28S ribosomal DNA (rDNA) repeats and validate this strategy for …

Mosquito Transposable Elements and piwi Genes
… The first subject is on a Long Terminal Repeat (LTR) retrotransposon in the African malaria mosquito, Anopheles gambiae, namely Belly. The second subject focuses on the characterization of piwi genes in the dengue and yellow fever mosquito, Aedes aegypti. For the first subject we characterized …

Molekulare Charakterisierung von Ty3-gypsy-Retrotransposons als abundante Sequenzklasse des Centromers eines Minichromosoms in Beta vulgaris L.
… die molekulare Charakterisierung von Ty3-gypsy-Retrotransposons eines einzelnen Wildrüben-Centromers möglich. Die für die Wildrübe Beta procumbens spezifischen Satellitenrepeats pTS5 und pTS4.1 dienten der Selektion von BACs aus der Centromer-Region des PRO1-Minichromosoms. Die Identifizierung …

Genetic studies of phenotypic variants in the woodland strawberry, (Fragaria vesca)
… in this line was located in a highly repetitive LTR retrotransposon region, which complicated analysis. Segregation analysis of the wr lines revealed that the phenotype was unassociated with the T-DNA insertion as well. We used a targeted expression analysis of three critical structural genes in …
