“…1). Tc1-like, pogo-like, and animal mariner-like transposases group into three distinct monophyletic clades, as previously shown (1,2,9). An additional group is composed of three invertebrate MLEs sharing a ''DD37D'' motif, two of which were previously described as basal mariners (9).…”

“…Furthermore, pairwise comparisons among Osmar1, Osmar2, Osmar3, Osmar4, and Os63, all from O. sativa, revealed only 46-61% identity. These results can be explained by postulating the existence of multiple ancestral lineages of transposases that diversified early in evolution [at least 50 million years (Myr) ago in the case of sorghum and rice (20,21)] and were vertically inherited (1,8,9).…”

“…Such phylogenetic discrepancies might be because of the horizontal transfer of MLEs between these species or between their ancestors. Horizontal transfer across wide taxonomic gaps has been well documented for animal MLEs and is believed to be important for the maintenance and propagation of DNA transposons (1,8,9). Resolving the dicot lineages and detecting horizontal transfer of plant MLEs will require a larger sampling of species as well as obtaining additional sequences per species.…”

“…This motif is part of the catalytic domain of the transposase and consists of two aspartic acid residues and a glutamic acid residue (or a third D) with characteristic spacing (2,7,8). A domain of Ϸ150 amino acids surrounding the acidic triad is relatively well-conserved and thus has served to establish the evolutionary relationships of Tc1͞mariner elements (1,2,7,9). On the basis of these studies, three distinct monophyletic groups have been distinguished: Tc1-like, mariner-like, and pogo-like (1,2,7,9).…”

Complete and partial sequences of mariner-like elements (MLEs) have been reported for hundreds of species of animals, but only two have been identified in plants. On the basis of these two plant MLEs and several related sequences identified by database searches, plant-specific degenerate primers were derived and used to amplify a conserved region of MLE transposase genes from a variety of plant genomes. Positive products were obtained for 6 dicots and 31 monocots of 54 plant species tested. Phylogenetic analysis of 68 distinct MLE transposase sequences from 25 grass species is consistent with vertical transmission and rapid diversification of multiple lineages of transposases. Surprisingly, the evolution of MLEs in grasses was accompanied by repeated and independent acquisition of introns in a localized region of the transposase gene.

“…Our explanation for the presence of several mammal mar1 populations in the mammalian genomes appears to be parsimonious and minimizes horizontal transfers as previously recommended in the literature (Capy et al 1996;Hartl et al 1997). However, it does not answer a controversial observation obtained by comparing the invertebrate and mammalian MLEs related to the cecropia sub-family.…”

Abstract. Mariner-like elements (MLE) belong to the Tc1/ mariner superfamily of class II transposons. We have analyzed the mariner related to the cecropia subfamily, and called mammal mar1, in four mammalian genomes, Bos taurus (Bovidae), Homo sapiens (Primata), Mus musculus (Rodentia), and Ovis aries (Ovidae). Three kinds of MLE sequences were found in all these species: full-length 1.3-kbp elements, shorter elements 80 bp-1.2 kbp, and single inverted terminal repeats (ITRs). All the 1.3-kbp genomic copies sequenced had an open reading frame encoding a transposase interrupted by stop codons or frame shifts. Phylogenetic analysis of the full-length elements suggested at least two distinct populations of mammal mar1 elements in each species. This was confirmed by using a statistical method that allows defining populations. Finally, the evolutionary origin of the mammal mar1 elements and the paradoxes are discussed.

A mariner-like element was cloned from the genome of the Asiatic honey bee, Apis cerana japonica (Hymenoptera, Apocrita). The (composite) clone, named Acmar1, was 1,378 bp long, and encoded 336 amino acids corresponding to a transposase-like putative polypeptide in a single open reading frame. The D,D(34)D motif, the catalytic domain of the mariner transposase, was present, although there was a deletion of five amino acid residues within it as compared with the active transposase in Drosophila mauritiana. Nineteen-bp-long imperfect inverted terminal repeat-like sequences flanked by TA dinucleotides, the typical target site for mariner insertion, were observed. Southern blot analysis using a fragment covering two-thirds of the Acmar1 transposase coding sequence as a probe indicated the presence of multiple Acmar1-like elements in the genome. Maximum-parsimony phylogenetic analysis based on the transposase amino acid sequences of insect mariner-like elements revealed that Acmar1 is a member of the mellifera subfamily.
