De novo identification of LTR retrotransposons in eukaryotic genomes [PDF]

BMC Genomics, 2007
Background LTR retrotransposons are a class of mobile genetic elements containing two similar long terminal repeats (LTRs). Currently, LTR retrotransposons are annotated in eukaryotic genomes mainly through the conventional homology searching approach ...

LTR retrotransposons in rice (Oryza sativa, L.): recent burst amplifications followed by rapid DNA loss [PDF]

BMC Genomics, 2007
Background LTR retrotransposons are one of the main causes for plant genome size and structure evolution, along with polyploidy. The characterization of their amplification and subsequent elimination of the genomes is therefore a major goal in plant ...

Long terminal repeats (LTR) and transcription factors regulate PHRE1 and PHRE2 activity in Moso bamboo under heat stress

BMC Plant Biology, 2021
Background LTR retrotransposons play a significant role in plant growth, genome evolution, and environmental stress response, but their regulatory response to heat stress remains unclear.

Mosquitoes LTR retrotransposons: a deeper view into the genomic sequence of Culex quinquefasciatus. [PDF]

PLoS ONE, 2012
A set of 67 novel LTR-retrotransposon has been identified by in silico analyses of the Culex quinquefasciatus genome using the LTR_STRUC program. The phylogenetic analysis shows that 29 novel and putatively functional LTR-retrotransposons detected belong

A highly conserved, small LTR retrotransposon that preferentially targets genes in grass genomes. [PDF]

PLoS ONE, 2012
LTR retrotransposons are often the most abundant components of plant genomes and can impact gene and genome evolution. Most reported LTR retrotransposons are large elements (>4 kb) and are most often found in heterochromatic (gene poor) regions.

Comparative analysis of miniature inverted–repeat transposable elements (MITEs) and long terminal repeat (LTR) retrotransposons in six Citrus species

BMC Plant Biology, 2019
Background Miniature inverted-repeat transposable elements (MITEs) and long terminal repeat (LTR) retrotransposons are ubiquitous in plants genomes, and highly important in their evolution and diversity.

Non-long terminal repeat (non-LTR) retrotransposons: mechanisms, recent developments, and unanswered questions

Mobile DNA, 2010
Non-long terminal repeat (non-LTR) retrotransposons are present in most eukaryotic genomes. In some species, such as humans, these elements are the most abundant genome sequence and continue to replicate to this day, creating a source of endogenous ...

Retrotranspositions in orthologous regions of closely related grass species

BMC Evolutionary Biology, 2006
Background Retrotransposons are commonly occurring eukaryotic transposable elements (TEs). Among these, long terminal repeat (LTR) retrotransposons are the most abundant TEs and can comprise 50–90% of the genome in higher plants.

Endonuclease domain of the Drosophila melanogaster R2 non-LTR retrotransposon and related retroelements: a new model for transposition

Frontiers in Genetics, 2013
The molecular mechanisms of the transposition of non-long terminal repeat (non-LTR) retrotransposons are not well understood; the key questions of how the 3’-ends of cDNA copies integrate and how site-specific integration occurs remain unresolved ...

CR1 clade of non-LTR retrotransposons from Maculinea butterflies (Lepidoptera: Lycaenidae): evidence for recent horizontal transmission

BMC Evolutionary Biology, 2007
Background Non-long terminal repeat (non-LTR) retrotransposons are mobile genetic elements that propagate themselves by reverse transcription of an RNA intermediate. Non-LTR retrotransposons are known to evolve mainly via vertical transmission and random
