We are happy to announce an updated bacterial and archaeal representative genomes collection. The current collection contains a total of 15,507 assemblies selected from 236,000 prokaryotic RefSeq assemblies to represent their respective species. The collection has grown by five percent since August 2021. A total of 685 species are represented for the first time. In addition, 370 species are represented by a better assembly, and 84 species were removed because of changes in NCBI Taxonomy or uncertainty in their species assignment.
We updated the database on the Microbial Nucleotide BLAST page as well as the basic nucleotide BLAST RefSeq Representative genomes database (fourth in the menu) to reflect these changes. Finally, remember that you can now run BLAST searches against the proteins annotated on representative genomes (second in the menu). Find more information here.
Great information thanks for sharing this information
