Data from: Has gene expression neofunctionalization in the fire ant antennae contributed to queen discrimination behavior?
<p>Queen discrimination behavior in the fire ant <i>Solenopsis invicta</i> maintains its two types of societies: colonies with one (monogyne) or many (polygyne) queens, yet the underlying genetic mechanism is poorly understood. This behavior is controlled by two supergene alleles, <i>SB</i> and <i>Sb,</i> with ~600 genes. Polygyne workers, having either the <i>SB/SB</i> or <i>SB/Sb </i>genotype, accept additional <i>SB/Sb</i> queens into their colonies but kill <i>SB/SB</i> queens. In contrast, monogyne workers, all <i>SB/SB</i>, reject all additional queens regardless of genotype. Because the <i>SB</i> and <i>Sb</i> alleles have suppressed recombination, determining which genes within the supergene mediate this differential worker behavior is difficult. We hypothesized that the alternate worker genotypes sense queens differently because of the evolution of differential expression of key genes in their main sensory organ, the antennae. To identify such genes, we sequenced RNA from four replicates of pooled antennae from three classes of workers: monogyne <i>SB/SB</i>, polygyne <i>SB/SB,</i> and polygyne <i>SB/Sb</i>. We identified 81 differentially expressed protein-coding genes with 13 encoding potential chemical metabolism or perception proteins. We focused on the two odorant perception genes: an odorant receptor<i> SiOR463</i> and an odorant binding protein <i>Si</i><i>OBP12</i>. We found that <i>SiOR463</i> has been lost in the <i>Sb</i>-genome. In contrast, <i>SiOBP12</i> has an <i>Sb</i>-specific duplication, <i>SiOBP12b'</i>, which is expressed in the <i>SB/Sb</i> worker antennae, while both paralogs are expressed in the body. Comparisons with another fire ant species revealed that <i>SiOBP12b'</i> antennal expression is specific to <i>S. invicta</i> and suggests that queen discrimination may have evolved, in part, through expression neofunctionalization.</p>
Raw and analysed data for contribution paper "Low temperature plasma deoxidation of copper surfaces"
<p><strong>Abstract</strong>: In this study, the application of a DBD plasma for metal deoxidation was shown on differently oxidized copper surfaces in an Ar/H<sub>2</sub> atmosphere at 100 hPa and room temperature. Plasma treatments with a discharge voltage of 11 kV and a frequency of 8.8 kHz yielded an almost complete deoxidation of samples with native Cu<sub>2</sub>O layers and samples with pre-oxidized CuO layers, both within minutes of the Ar/H<sub>2</sub> plasma treatment. The chemical state of the samples was characterized via X-ray photoelectron spectroscopy (XPS). The plasma was analysed by optical emission spectroscopy (OES). Additionally, confocal laser scanning microscopy (CLSM) images show that the employed deoxidation method did not change the morphology of the copper surfaces.</p>
Data from: Assessing the contributions of intraspecific and environmental sources of infection in urban wildlife: Salmonella enterica and white ibis as a case study
Conversion of natural habitats into urban landscapes can expose wildlife to novel pathogens and alter pathogen transmission pathways. Because transmission is difficult to quantify for many wildlife pathogens, mathematical models paired with field observations can help select among competing transmission pathways that might operate in urban landscapes. Here we develop a mathematical model for the enteric bacteria Salmonella enterica in urban-foraging white ibis (Eudocimus albus) in south Florida as a case study to determine (i) the relative importance of contact-based versus environmental transmission among ibis and (ii) whether transmission can be supported by ibis alone or requires external sources of infection. We use biannual field prevalence data to restrict model outputs generated from a Latin hypercube sample of parameter space and select among competing transmission scenarios. We find the most support for transmission from environmental uptake rather than between-host contact and that ibis–ibis transmission alone could maintain low infection prevalence. Our analysis provides the first parameter estimates for Salmonella shedding and uptake in a wild bird and provides a key starting point for predicting how ibis response to urbanization alters their exposure to a multi-host zoonotic enteric pathogen. More broadly, our study provides an analytical roadmap to assess transmission pathways of multi-host wildlife pathogens in the face of scarce infection data.

Early postzygotic mutations contribute to de novo variation in a healthy monozygotic twin pair.
<p>Human de novo single-nucleotide variation (SNV) rate is estimated to range between 0.82-1.70×10(-8) mutations per base per generation. However, contribution of early postzygotic mutations to the overall human de novo SNV rate is unknown.</p> <p>METHODS:</p> <p>We performed deep whole-genome sequencing (more than 30-fold coverage per individual) of the whole-blood-derived DNA samples of a healthy monozygotic twin pair and their parents. We examined the genotypes of each individual simultaneously for each of the SNVs and discovered de novo SNVs regarding the timing of mutagenesis. Putative de novo SNVs were validated using Sanger-based capillary sequencing.</p> <p>RESULTS:</p> <p>We conservatively characterised 23 de novo SNVs shared by the twin pair, 8 de novo SNVs specific to twin I and 1 de novo SNV specific to twin II. Based on the number of de novo SNVs validated by Sanger sequencing and the number of callable bases of each twin, we calculated the overall de novo SNV rate of 1.31×10(-8) and 1.01×10(-8) for twin I and twin II, respectively. Of these, rates of the early postzygotic de novo SNVs were estimated to be 0.34×10(-8) for twin I and 0.04×10(-8) for twin II.</p> <p>CONCLUSIONS:</p> <p>Early postzygotic mutations constitute a substantial proportion of de novo mutations in humans. Therefore, genome mosaicism resulting from early mitotic events during embryogenesis is common and could substantially contribute to the development of diseases.</p>
