| reevaluating the infection status by the wolbachia endosymbiont in drosophila neotropical species from the willistoni subgroup. | infections by the endosymbiotic bacterium wolbachia developed a rapid global expansion within old world drosophila species, ultimately infecting also neotropical species. in this sense, screenings are necessary to characterize new variants of wolbachia or new hosts, and also in order to map the dynamics of already known infections. in this paper, we performed a double screening approach that combined dot-blot and pcr techniques in order to reevaluate the infection status by wolbachia in species ... | 2013 | 23906981 |
| sex-specific methylation in drosophila: an investigation of the sophophora subgenus. | epigenetic phenomena have been widely characterized in the genomes of vertebrates and dna methylation is a key mechanism of epigenetic regulation. the dna methylation systems of invertebrates and vertebrates show several notable differences. however, the evolutionary implications of those differences only recently began to be revealed. our study investigated the recurrence of sex-specific methylation, as previously described for the species drosophila willistoni, in other species of the sophopho ... | 2010 | 20640488 |
