| Wolbachia are endosymbiotic bacteria that commonly infect arthropods, inducing certain phenotypes in their hosts. So far, no endemic South American species of terrestrial isopods have been investigated for Wolbachia infection. In this work, populations from two species of Balloniscus (B. sellowii and B. glaber) were studied through a diagnostic PCR assay. Fifteen new Wolbachia 16S rDNA sequences were detected. Wolbachia found in both species were generally specific to one population, and five populations hosted two different Wolbachia 16S rDNA sequences. Prevalence was higher in B. glaber than in B. sellowii, but uninfected populations could be found in both species. Wolbachia strains from B. sellowii had a higher genetic variation than those isolated from... |

| Insetos e outros artrópodes são hospedeiros comuns de bactérias transmitidas por via materna (Duron; Hurst, 2013). Esses endossimbiontes hereditários podem ter uma forte influência na ecologia do hospedeiro. Tais bactérias transmitidas verticalmente são numerosas e dependentes do hospedeiro para sobrevivência e transmissão. Certas associações são obrigatórias para ambos os parceiros, e geralmente envolvem um benefício nutricional para o hospedeiro. Outras bactérias hereditárias são facultativas e variam, em associações, de mutualistas a parasitas quando observadas sob a perspectiva do hospedeiro. Entre estas, a Wolbachia é a mais comum e a mais difundida simbionte facultativa de insetos e artrópodes (Hilgenboecker et al., 2008; Zug; Hammerstein, 2012). |

| Cytoplasmic components and their interactions with the nuclear genome may mediate patterns of phenotypic expression to form a joint inheritance system. However, proximate mechanisms underpinning these interactions remain elusive. To independently assess nuclear genetic and epigenetic cytoplasmic effects, we created a full-factorial design in which representative cytoplasms and nuclear backgrounds from each of two geographically disjunct populations of Drosophila melanogaster were matched together in all four possible combinations. To capture slowly-accumulating epimutations in addition to immediately occurring ones, these constructed populations were examined one year later. We found the K4 methylation of histone H3, H3K4me3, an epigenetic marker... |
