In Dec 2010, the Human Genome Sequencing Center at Baylor College of Medicine released Bter_1.0, a ~21.4x coverage assembly of the genome sequence of Bombus terrestris (buff-tailed bumblebee) using NextGen (Roche 454) sequencing. The bumblebee genome is estimated to be 274 Mbp organized as 18 chromosomes. Scaffolds were assembled into linkage groups based on data from Stolle et al 2011. The genome sequence was annotated using NCBI's eukaryotic genome annotation pipeline. Predictions were based on B. terrestris RNAseq data generated by the Baylor College of Medicine, Mark Brown's group at Royal Holloway, University of London, and Gene Robinson's group at the University of Illinois, and also alignment of protein sequences from Apis mellifera and other species.

The NCBI Map Viewer provides graphical displays of features on the Bombus terrestris genome sequence assembly. Map features that can be seen along the sequence include NCBI contigs (the Contig map), the WGS sequences (the Component map), and the location of aligned transcripts from Bombus terrestris (rnaBte) and other insects (rnaIns). The gene on sequence map includes both known genes and putative genes based on predictions from NCBI's eukaryotic genome annotation pipeline. The complete set of Gnomon predicted gene models can be viewed on the Model Transcripts map. Further documentation is provided on the Bombus terrestris genome data and search tips page and through the links below to describe the resource features and methods used, tutorials, and statistics.

The Search bar or the BLAST search link above can be used to find annotation or sequence in the assembly. The sequence-based maps for any contig of interest can then be displayed. Results are indicated in a tabular format. The results table includes links to a contig graphical view where the gene or marker can be seen in the context of additional data. For genes, a particularly useful display includes the Gene, RefSeq transcript, and rnaBte sequence maps. Use the "Maps & Options" window to configure each display.

Other genomes can also be viewed in the NCBI Map Viewer. The Map Viewer home page provides a current list.
