Only three retrotransposons of the DIRS1 group have previously been described: DIRS1 from the slime mold Dictyostelium discoideum, PAT from the nematode Panagrellus redivivus, and Prt1 from the zygomycetous fungus Phycomyces blakesleeanus. Analyses of the reverse transcriptase sequences encoded by these elements suggest that they are related to the long terminal repeat (LTR) retroelements, such as the Ty3/gypsy retrotransposons and the vertebrate retroviruses. The DIRS1-group elements, however…

DIRS-1 and the other tyrosine recombinase retrotransposons
TLDR
The complete set of YR retrotransposons can be divided into two major groups, the DIRS elements and the Ngaro elements, the two groups forming distinct clades on phylogenetic trees based on alignments of RT/RH and recombinase sequences, and also having some structural distinctions.
Tyrosine Recombinase Retrotransposons and Transposons.
TLDR
It is suggested that the YR retrotransposons arose from the combination of a crypton-like YR DNA transposon and the RT/RH encoding sequence of a Retrotransposon, which must have occurred at a very early point in the evolution of eukaryotes.
Eukaryote DIRS1-like retrotransposons: an overview
TLDR
This study reports 14 new species and 8 new higher taxa that were not previously known to harbor DIRS1-like retrotransposons, which appear widely distributed among eukaryotes, even if they remain undetected in streptophytes and mammals.
A new group of tyrosine recombinase-encoding retrotransposons.
TLDR
The Ngaro and DIRS groups of YR retrotransposons contain elements with an astonishing diversity in structures, with variations in the nature of the associated repeat sequences and in the arrangement and complement of coding regions.
DIRS retroelements in arthropods: identification of the recently active TcDirs1 element in the red flour beetle Tribolium castaneum
TLDR
The first DIRS retroelement to be identified in an arthropod was found in the red flour beetle Tribolium castaneum (Coleoptera), and TcDirs1 elements exhibit several features indicative of recent activity, such as intact coding regions, a high level of sequence similarity between distinct elements and polymorphic insertion sites.
kangaroo, a mobile element from Volvox carteri, is a member of a newly recognized third class of retrotransposons.
TLDR
It is shown that DIRS-1 and DrDIRS1 elements contain terminal features structurally related to SDRs, which appear to define a third class of retrotransposons that are unified by common structural features, genes, and integration mechanisms, all of which differ from those of LTR and conventional non-LTR retro Transposons.
LTR retroelements in the genome of Daphnia pulex
TLDR
A genome-wide analysis of LTR retroelements in Daphnia pulex, a cyclical parthenogen and the first crustacean for which the whole genomic sequence is available, provides insight into the potential impact of LRS activity in the evolution of other genomes.
The unusual phylogenetic distribution of retrotransposons: a hypothesis.
TLDR
A cap and tail hypothesis is proposed, which states that the specialized terminal structures of eukaryotic mRNA provide the ideal molecular environment for the lengthening, evolution, and subsequent massive expansion of highly mobile retrotransposons, leading directly to the Retrotransposon-cluttered structure that typifies modern metazoan genomes and the eventual emergence of retroviruses.
DIRS retrotransposons amplify via linear, single-stranded cDNA intermediates
TLDR
This work provides the first experimental evidence to propose a general retrotransposition mechanism of the class of DIRS like tyrosine recombinase retrotransposons, and produces a mixture of single-stranded, mostly linear extrachromosomal cDNA intermediates.
Cryptons: a group of tyrosine-recombinase-encoding DNA transposons from pathogenic fungi.
A new group of transposable elements, which the authors have named cryptons, was detected in several pathogenic fungi, including the basidiomycete Cryptococcus neoformans, and the ascomycetes

Prt1, an unusual retrotransposon-like sequence in the fungus Phycomyces blakesleeanus
TLDR
The isolation and structural characterization of Prt1, a 4.7 kb retrotransposon-like sequence from the filamentous fungus Phycomyces blakesleeanus is reported, which lacks long terminal repeats and encodes peptide stretches similar to the reverse transcriptase and RNaseH domains of the Ty3/gypsy family of LTR-retrotransposons.
Unusual features of the retroid element PAT from the nematode Panagrellus redivivus.
The PAT retroid transposable elements differ from other retroids in that they have a 'split direct repeat' structure, i.e., and internal 300bp sequence is found repeated, about one half at each
Poised for contagion: evolutionary origins of the infectious abilities of invertebrate retroviruses.
TLDR
Evidence is presented that in three other possible transitions of LTR retrotransposons to retroviruses, an envelope-like gene was acquired from a viral source, representing the only cases in which the env gene of a retrovirus has been traced back to its original source.
Origin and evolution of retroelements based upon their reverse transcriptase sequences.
TLDR
The sequence similarity of these RNA polymerases to RT suggests that these two enzymes evolved from a common ancestor, and thus RNA polymerase can be used as an outgroup to root the RT tree.
Retroviruses in invertebrates: the gypsy retrotransposon is apparently an infectious retrovirus of Drosophila melanogaster.
TLDR
It is reported here experiments showing that gypsy can be transmitted by microinjecting egg plasma from embryos of a strain containing actively transposing gypsy elements into embryos ofA strain originally devoid of transposing elements, and evidence that retroviruses also occur in invertebrates is provided.
SIRE-1, a copia/Ty1-like retroelement from soybean, encodes a retroviral envelope-like protein.
TLDR
This finding suggests the presence of a proretrovirus in a plant genome and is the strongest evidence to date for the existence of a retrovirus-like genome closely related to copia/Ty1 retrotransposons.
Dictyostelium transposable element DIRS-1 preferentially inserts into DIRS-1 sequences.
TLDR
A cDNA clone is described which could be derived by transcription of a sequence that resulted from a DIRS-1-into-DIRS- 1 insertion and its significance concerning the function of the heat-shock promoters found in the terminal repeats of DIRs-1 and in other DirS-2-related sequences is discussed.
Characterization and repeat analysis of the compact genome of the freshwater pufferfish Tetraodon nigroviridis.
TLDR
The previously uncharacterized Tetraodon genome is described here together with a detailed analysis of its repeat content and organization, and the sequencing of 46 megabases of bacterial artificial chromosome end sequences, which represents a random DNA sample equivalent to 13% of the genome.
