Evolutionary dynamics in a novel L2 clade of non-LTR retrotransposons in Deuterostomia.
The evolution of the novel L2 clade of non-long terminal repeat (LTR) retrotransposons and their evolutionary dynamics in Deuterostomia has been examined. The short-term evolution of long interspersed nuclear element 2s (LINE2s) has been studied in 18 reptilian species by analysis of a PCR amplified 0.7-kb fragment encoding the palm/fingers subdomain of reverse transcriptase (RT). Most of the r...
متن کاملEvolution of target specificity in R1 clade non-LTR retrotransposons.
Although most non-long terminal repeat (non-LTR) retrotransposons are inserted throughout the host genome, many non-LTR elements in the R1 clade are inserted into specific sites within the target sequence. Four R1 clade families have distinct target specificity: R1 and RT insert into specific sites of 28S rDNA, and TRAS and SART insert into different sites within the (TTAGG)(n) telomeric repeat...

متن کاملEvolutionary Dynamics of the Ty3/Gypsy LTR Retrotransposons in the Genome of Anopheles gambiae
Ty3/gypsy elements represent one of the most abundant and diverse LTR-retrotransposon (LTRr) groups in the Anopheles gambiae genome, but their evolutionary dynamics have not been explored in detail. Here, we conduct an in silico analysis of the distribution and abundance of the full complement of 1045 copies in the updated AgamP3 assembly. Chromosomal distribution of Ty3/gypsy elements is inver...
متن کاملThe evolutionary dynamics of autonomous non-LTR retrotransposons in the lizard Anolis carolinensis shows more similarity to fish than mammals.
The genome of the lizard Anolis carolinensis (the green anole) is the first nonavian reptilian genome sequenced. It offers a unique opportunity to comparatively examine the evolution of amniote genomes. We analyzed the abundance and diversity of non-LTR (long terminal repeat) retrotransposons in the anole using the Genome Parsing Suite. We found that the anole genome contains an extraordinary d...
