ABSTRACT: Genome sequences and bird genomes assemblies for the Danish Bird Genome (DBG) project under the B10K consortium Genome sequencing and assembly
Project description:The Zika outbreak, spread by the Aedes aegypti mosquito, highlights the need to create high-quality assemblies of large genomes in a rapid and cost-effective fashion. Here, we combine Hi-C data with existing draft assemblies to generate chromosome-length scaffolds. We validate this method by assembling a human genome, de novo, from short reads alone (67X coverage, Sample GSM1551550). We then combine our method with draft sequences to create genome assemblies of the mosquito disease vectors Aedes aegypti and Culex quinquefasciatus, each consisting of three scaffolds corresponding to the three chromosomes in each species. These assemblies indicate that virtually all genomic rearrangements among these species occur within, rather than between, chromosome arms. The genome assembly procedure we describe is fast, inexpensive, accurate, and can be applied to many species.
Project description:Peanut (Arachis hypogaea) has a large (~2.7 Gbp) allotetraploid genome with closely related component genomes making its genome very challenging to assemble. Here we report genome sequences of its diploid ancestors (A. duranensis and A. ipaënsis). We show they are similar to the peanut’s A- and B-genomes and use them use them to identify candidate disease resistance genes, create improved tetraploid transcript assemblies, and show genetic exchange between peanut’s component genomes. Based on remarkably high DNA identity and biogeography, we conclude that A. ipaënsis may be a descendant of the very same population that contributed the B-genome to cultivated peanut.

Project description:Comparative genomic hybridisation of genomic DNA from avian species to the Roche NimbleGen chicken whole genome oligonucleotide array. The purpose was to identify copy number variants between the given species and chicken. The starting material was blood or feather pulp from a variety of bird species, from which we performed DNA extractions.
Project description:This RNA sequencing data set of 465 human lymphoblastoid cell line samples from the CEU, FIN, GBR, TSI and YRI populations from the 1000 Genomes sample collection was created by the Geuvadis consortium (www.geuvadis.org, http://www.geuvadis.org/web/geuvadis/our-rnaseq-project). The data is under embargo until the first publication by the investigators in early 2013. This accession contains small RNA sequencing data, and mRNA data from the same samples are available under accession E-GEUV-1.
