“…Among all transposon families discovered to date, DD34D/mariner is the most widely distributed and appears in almost all bee genomes. In addition, DD34D/mariner is also widely distributed in nature and has been reported in all species [39,[78][79][80][81][82]. The distribution of transposons differs between species, but the distribution of transposons is similar in sister species, which suggests that transposons invade the host's genome before species divergence.…”

Bees (Apoidea), the largest and most crucial radiation of pollinators, play a vital role in the ecosystem balance. Transposons are widely distributed in nature and are important drivers of species diversity. However, transposons are rarely reported in important pollinators such as bees. Here, we surveyed 37 bee genomesin Apoidea, annotated the pogo and Tc1/mariner transposons in the genome of each species, and performed a phylogenetic analysis and determined their overall distribution. The pogo and Tc1/mariner families showed high diversity and low abundance in the 37 species, and their proportion was significantly higher in solitary bees than in social bees. DD34D/mariner was found to be distributed in almost all species and was found in Apis mellifera, Apis mellifera carnica, Apis mellifera caucasia, and Apis mellifera mellifera, and Euglossa dilemma may still be active. Using horizontal transfer analysis, we found that DD29-30D/Tigger may have experienced horizontal transfer (HT) events. The current study displayed the evolution profiles (including diversity, activity, and abundance) of the pogo and Tc1/mariner transposons across 37 species of Apoidea. Our data revealed their contributions to the genomic variations across these species and facilitated in understanding of the genome evolution of this lineage.

“…It belongs to the order TIR (Terminal Inverted Repeat) and the superfamily Tc1-Mariner, and is widespread among metazoans (Augé-Gouillou et al 1995;Garcia-Fernàndez et al 1995;Ren et al 2006;Robertson and MacLeod 1993;Silva et al 2005;Sinzelle et al 2006). The broad distribution of MLEs can be explained, in part, by their incredible ability to move between genomes, a phenomenon known as Horizontal Transfer (HT) (Brunet et al 1999;Maruyama and Hartl 1991b;Laha et al 2007;Lampe et al 2003;Robertson 1997;Robertson and Lampe 1995;Yoshiyama et al 2001).…”

The evolutionary history of mariner-like elements in Neotropical drosophilids

et al. 2011

The evolutionary history of mariner-like elements (MLEs) in 49 mainly Neotropical drosophilid species is described. So far, the investigations about the distribution of MLEs were performed mainly using hybridization assays with the Mos1 element (the first mariner active element described) in a widely range of drosophilid species and these sequences were found principally in species that arose in Afrotropical and Sino-Indian regions. Our analysis in mainly Neotropical drosophilid species shows that twenty-three species presented MLEs from three different subfamilies in their genomes: eighteen species had MLEs from subfamily mellifera, fifteen from subfamily mauritiana and three from subfamily irritans. Eleven of these species exhibited elements from more than one subfamily in their genome. In two subfamilies, the analyzed coding region was uninterrupted and contained conserved catalytic motifs. This suggests that these sequences were probably derived from active elements. The species with these putative active elements are Drosophila mediopunctata and D. busckii for the mauritiana subfamily, and D. paramediostriata for the mellifera subfamily. The phylogenetic analysis of MLE, shows a complex evolutionary pattern, exhibiting vertical transfer, stochastic loss and putative events of horizontal transmission occurring between different Drosophilidae species, and even those belonging to more distantly related taxa such as Bactrocera tryoni (Tephritidae family), Sphyracephala europaea (Diopsoidea superfamily) and Buenoa sp. (Hemiptera order). Moreover, our data show that the distribution of MLEs is not restricted to Afrotropical and Sino-Indian species. Conversely, these TEs are also widely distributed in drosophilid species arisen in the Neotropical region.

“…[1] Mariner elements are the most successful family of autonomous DNA transposons, and are found in various plant and animal genomes, including human. [2,3] They are short DNA sequences (1 .3 kb) with a very simple organisation: a single gene encoding the transposase bracketed by short, inverted terminal repeats (ITRs, 28-30 bp). Data accumulated over the past decade (Mos1 from Drosophila mauritiana, Himar1 from Haematobia irritans, Hsmar1 from Homo sapiens) have led to a convergent picture of the transposition cycle of mariner elements.…”

Kinetic Analysis of the Interaction of Mos1 Transposase with its Inverted Terminal Repeats Reveals New Insight into the Protein–DNA Complex Assembly

et al. 2014

Transposases are specific DNA-binding proteins that promote the mobility of discrete DNA segments. We used a combination of physicochemical approaches to describe the association of MOS1 (an eukaryotic transposase) with its specific target DNA, an event corresponding to the first steps of the transposition cycle. Because the kinetic constants of the reaction are still unknown, we aimed to determine them by using quartz crystal microbalance on two sources of recombinant MOS1: one produced in insect cells and the other produced in bacteria. The prokaryotic-expressed MOS1 showed no cooperativity and displayed a Kd of about 300 nM. In contrast, the eukaryotic-expressed MOS1 generated a cooperative system, with a lower Kd (∼ 2 nm). The origins of these differences were investigated by IR spectroscopy and AFM imaging. Both support the conclusion that prokaryotic- and eukaryotic-expressed MOS1 are not similarly folded, thereby resulting in differences in the early steps of transposition.
