About the origin of retroviruses and the co-evolution of the , retrovirus with the , host gene At that time, . presumably contained permissive alleles of the . gene. One can imagine that the species survived to the increase of genetic load caused by the retroviral invasion because restrictive alleles of . were selected. the characterization of a retrovirus in ., one of the most advanced mode

Do the integrases of LTR-retrotransposons and class II element transposases have a common ancestor?tral origin(s) for the integrases and transposases containing the DDE signature. the position of the telomeric elements (. and .) was assessed by comparing their . and reverse transcriptase domains (when present) to those of group II introns and non-LTR retrotransposons. This preliminary analysis su

Genetic and molecular investigations on the endogenous mobile elements of non-drosophilid fruitflies phylogenetic analyses showed that the . elements isolated in the present study are representatives of Robertson’s mellifera . subfamily. the copy numbers of the elements within each species are very different, ranging from about 10 in . to 5000 in C. ..

Plant S1 SINEs as a model to study retropositionly to the characterization of genomic elements active in transcription and retroposition so that the cellular control of these elements can be addressed. Finally, we show that the study of S1 insertion sites can reveal information on the RNA reverse transcription and integration step of the retropos
