Project description:Genomic evidence suggests further changes of butterfly names

Project description:Studies of ancient DNA have revolutionized our understanding of extinct organisms, but thus far the maximum estimated age of sequenced DNA is two million years. However, evidence for endogenous biomolecules, including proteins, lipids, and pigments have been found in much older fossils, dating to up to 195 million years. Amino acid sequence data consistent with ancient, endogenous biomolecules have been derived from specimens of the theropod Tyrannosaurus rex (MOR 1125) and the hadrosaur Brachylophosaurus canadensis (MOR 2598). Histochemical and immunological studies also identified a molecule consistent with DNA in these two ancient specimens, localized to a single point within preserved osteocytes. Here we report the sequencing and analysis of DNA extracted from osteocytes and blood vessels of T. rex and B. canadensis, liberated after demineralization of dense cortical bone. Usable sequence reads were obtained at a low recovery rate. After the removal of high-quality reads that mapped to the human genome, the remaining reads were highly fragmented, with similarities to multiple animal species including reptilian and avian genomes. Our findings support the hypothesis that DNA and histone signal from imaging, mass spectrometry, and DNA sequencing of dinosaur osteocytes are endogenously preserved biomolecules.

Project description:We use RNAseq data to perform differential gene expression to identify genes controlling structural colouration in two co-mimetic species of Heliconius butterfly - Heliconius erato and Heliconius melpomene. We use comparisons between iridescent and non-iridescent subspecies of Helcionius erato (H. e. cyrbia and H. e. demophoon, respectively) and Helcionius melpomene (H. m. cythera and H. m. rosina, respectively) at two separate developmental stages, 50% and 70% of development. In addition, in the iridescent subspecies of both H. erato and H. melpomene, we compared the iridescent wing regions (forewing and hindwing combined) to the non-iridescent androconial wing region using differential gene expression.

Project description:BackgroundThe Natural History Museum, London (NHMUK) has embarked on an ambitious programme to digitise its collections . The first phase of this programme has been to undertake a series of pilot projects that will develop the necessary workflows and infrastructure development needed to support mass digitisation of very large scientific collections. This paper presents the results of one of the pilot projects - iCollections. This project digitised all the lepidopteran specimens usually considered as butterflies, 181,545 specimens representing 89 species from the British Isles and Ireland. The data digitised includes, species name, georeferenced location, collector and collection date - the what, where, who and when of specimen data. In addition, a digital image of each specimen was taken. This paper explains the way the data were obtained and the background to the collections which made up the project.New informationSpecimen-level data associated with British and Irish butterfly specimens have not been available before and the iCollections project has released this valuable resource through the NHM data portal.

Project description:It is debated to what extent individual regulatory genes might underlie non-gradualistic evolution of complex morphological traits. We have shown that a single regulatory gene, optix, is required for development of all color and iridescence in nymphalid butterfly wings by CRISPR/Cas9 genome editing. To investigate how wing features are controlled by optix, we used mRNA-seq to compare transcript abundance in wild type and optix knockout wings of V. cardui and J. coenia. We generated an average of 269 million reads 36 bp paired-end Nexseq 500 reads from 16 libraries and identified numerous candidate genes including known genes involved in the insect melanin and ommochrome biosynthetic pathways and suspected components potential involved in scale structure.

Project description:Ancient DNA (aDNA) sequencing has enabled reconstruction of speciation, migration, and admixture events for extinct taxa. Outside the permafrost, however, irreversible aDNA post-mortem degradation has so far limited aDNA recovery to the past ~0.5 million years (Ma). Contrarily, multiple analyses suggested the presence of protein residues in Cretaceous fossil remains. Similarly, tandem mass spectrometry (MS) allowed sequencing ~1.5 million year (Ma) old collagen type I (COL1), though with limited phylogenetic use. In the absence of molecular evidence, the speciation of several Early and Middle Pleistocene extinct species remain contentious. In this study, we address the phylogenetic relationships of the Eurasian Pleistocene Rhinocerotidae using a ~1.77 Ma old dental enamel proteome of a Stephanorhinus specimen from the Dmanisi archaeological site in Georgia (South Caucasus). Molecular phylogenetic analyses place the Dmanisi Stephanorhinus as a sister group to the woolly (Coelodonta antiquitatis) and Merck’s rhinoceros (S. kirchbergensis) clade. We show that Coelodonta evolved from an early Stephanorhinus lineage and that the latter includes at least two distinct evolutionary lines. As such, the genus Stephanorhinus is currently paraphyletic and requires systematic revision. We demonstrate that Early Pleistocene dental enamel proteome sequencing overcomes the limits of ancient collagen- and aDNA-based phylogenetic inference. It also provides additional information about the sex and taxonomic assignment of the specimens analysed. Dental enamel, the hardest tissue in vertebrates, is highly abundant in the fossil record. Our findings reveal that palaeoproteomic investigation of this material can push biomolecular investigation further back into the Early Pleistocene.
