Gill Structure Linked to Ecological and Species Diversification in a Clade of Caddisflies Open
Streams represent a special case of directional environmental gradients where ecological opportunity for diversification may be associated with upstream and downstream dispersal into habitats that differ in selective pressures. Temperature…
Clonal dynamics underlying the skewed CD4/CD8 ratio of mouse thymocytes revealed by TCR-independent barcoding Open
T cell differentiation in the thymus generates CD4 + helper and cytotoxic CD8 + cells as the two principal T cell lineages. Curiously, at the end of this complex selection process, CD4 + cells invariably outnumber CD8 + cells. Here, we exa…

Transposable Elements in the Genome of the Lichen-Forming Fungus Umbilicaria pustulata and Their Distribution in Different Climate Zones along Elevation Open
Transposable elements (TEs) are an important source of genome plasticity across the tree of life. Drift and natural selection are important forces shaping TE distribution and accumulation. Fungi, with their multifaceted phenotypic diversit…
Intrasexual cuticular hydrocarbon dimorphism in a wasp sheds light on hydrocarbon biosynthesis genes in Hymenoptera Open
Cuticular hydrocarbons (CHCs) cover the cuticle of insects and serve as desiccation barrier and for chemical communication. While the main enzymatic steps of CHC biosynthesis are well understood, few of the underlying genes have been ident…
Transposable elements in the genome of the lichen-forming fungus <i>Umbilicaria pustulata</i> , and their distribution in different climate zones along elevation Open
Background Transposable elements (TEs) are an important source of genome plasticity across the tree of life. Accumulating evidence suggests that TEs may not be randomly distributed in the genome. Drift and natural selection are important f…

Viromics of extant insect orders unveil the evolution of the flavi-like superfamily Open
Insects are the most diversified and species-rich group of animals and harbor an immense diversity of viruses. Several taxa in the flavi-like superfamily, such as the genus Flavivirus, are associated with insects; however, systematic studi…
Transposable elements in the genome of the lichen-forming fungus Umbilicaria pustulata, and their distribution in different climate zones along elevation Open
Here we report TEs found in a high quality reference genome of the lichen-forming fungus Umbilicaria pustulata.The fungal symbiont of U. pustulata comprises two climatic ecotypes: Mediterranean and cold-temperate. We implemented a Pool-Seq…

Beyond Drosophila: resolving the rapid radiation of schizophoran flies with phylotranscriptomics Open
Background The most species-rich radiation of animal life in the 66 million years following the Cretaceous extinction event is that of schizophoran flies: a third of fly diversity including Drosophila fruit fly model organisms, house flies…
Education in the genomics era: Generating high-quality genome assemblies in university courses Open
Recent advances in genome sequencing technologies have simplified the generation of genome data and reduced the costs for genome assemblies, even for complex genomes like those of vertebrates. More practically oriented genomic courses can …
Data for: The immunogenetics of sexual parasitism Open
Aligned amino acid sequences of 946 orthologous exon loci that were used to obtain a phylogeny of 13 anglerfish species. The locus sequences were obtained using a best hit search using TBLASTN v2.9.0 with the consensus amino acid sequences…

Sawfly Genomes Reveal Evolutionary Acquisitions That Fostered the Mega-Radiation of Parasitoid and Eusocial Hymenoptera Open
The tremendous diversity of Hymenoptera is commonly attributed to the evolution of parasitoidism in the last common ancestor of parasitoid sawflies (Orussidae) and wasp-waisted Hymenoptera (Apocrita). However, Apocrita and Orussidae differ…
