This blog post is directed toward Assembly users.
A new “Download assemblies” button is now available in the Assembly database. This makes it easy to download data for multiple genomes without having to write scripts.
For example, you can run a search in Assembly and use check boxes (see left side of screenshot below) to refine the set of genome assemblies of interest. Then, just open the “Download assemblies” menu, choose the source database (GenBank or RefSeq), choose the file type, and start the download. An archive file will be saved to your computer that can be expanded into a folder containing your selected genome data files.
The Tasmanian devil (Sarcophilus harrisii), the last remaining large marsupial carnivore, now faces extinction because of a strange and deadly infection, a transmissible cancer known as Transmissible Devil Facial Tumor Disease (TDFTD). In a previous NCBI Insights post, we discussed gene expression data from the tumors that established their neural origin and showed the tumors were likely derived from Schwann cells. In this post, we’ll consider some of the genome sequencing projects in the NCBI databases and explore evidence that the tumor originated in a different individual than the affected animal supporting the idea that the tumor cells themselves are infectious agents.
