“…In contrast with previous studies (Castro et al 2006;Germanos et al 2006;Loreto et al 1998), we found that the subfamily mauritiana is widely distributed in the Fig. 2 Phylogeny of MLEs using a Bayesian analysis with the JTT?G model.…”

“…Subsequent studies searching for related sequences in Drosophilidae species were performed, most of which used hybridization assays with Dromar or Mos1 as probes (Biémont and Cizeron 1999;Brunet et al 1994Brunet et al , 1999Capy et al 1992;Castro et al 2006;Germanos et al 2006;Loreto et al 1998 andHartl 1991a). These studies were largely focused on the Drosophila genus, though some species of Zaprinonus, Scaptomyza, Zygothrica, Chymomyza and Scaptodrosophila were also analyzed.…”

The evolutionary history of mariner-like elements in Neotropical drosophilids

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.
