Non-LTR Retrotransposons in Mosquitoes: Diversity, Evolution, and Analysis of Potentially Active Elements
… focuses on non-Long Terminal Repeat (non-LTR) retrotransposons in the African malaria mosquito, Anopheles gambiae and other mosquito species. An unprecedented diversity of non-LTRs was discovered by genome analysis of the An. gambiae genome assembly. One hundred and four families were …

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 …

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 …

Exploring the TE landscape of elephant and CR1 accumulation, evolution and effects of selection in the class Chondrichthyes
… much of the genome (29%) was composed of non-LTR retrotransposons such as SINE and LINES. Interestingly the LINE CR1 showed peaks of accumulation in the distant past. We estimated that these insertions occurred ~ 400 million years ago (mya). Further investigation was performed to better …

Regulation of the ETn/MusD family of active mouse long terminal repeat retrotransposons
Long terminal repeat (LTR) retrotransposons account for approximately 10% of mouse and 8% of human genomes and may play a role in modifying gene expression. Many species harbor retrotransposon families encompassing both autonomous and non-autonomous members. Specifically, the mouse Early Transposon …

The role of mobile elements in recent primate genomes
… type of MEs, which we term “retro-DNA” for non-LTR retrotransposons derived from DNA transposons, in the recent primate genomes. By investigating biallelic DNA transposons that have both the insertion and pre-integration alleles in ten primate genomes, a total of 1,750 retro-DNA elements …

Bioinformatics Investigation on the Role of Obox Gene Family in Preimplantation Embryo Development
… (47 were found in Emsembl), which implied that retrotransposons could affect the activation of Obox genes. We analyzed Obox genomic sequences by scanning the LTR retrotransposons showing that 5’-UTR of Obox contain LTR elements and belong to ERV-1, ERVL-MaLR and ERVK family. Due to the binding …

Análisis de variabilidad de secuencia in vivo de RNAs circulares con ribozimas
… se han descubierto retrotransposones LTR no autónomos que se expresan como RNAs circulares con ribozimas HHR, bautizados como retrozimas. En este estudio se ha realizado un análisis detallado de la variabilidad natural de un retrozima de Fragaria ananassa bajo diversas condiciones. …

Diversity and Evolution of Short Interspersed Nuclear Elements (SINEs) in Angiosperm and Gymnosperm Species and their Application as molecular Markers for Genotyping
… are small non-autonomous and heterogeneous retrotransposons, widespread in animals and plants and usually differentially propagated in related species resulting in genome-specific copy numbers. Within the monocots, the Poaceae (sweet grasses) is the largest and economically most important …
