An updated\u00a0bacterial and archaeal reference genome collection<\/a>\u00a0is available! This collection of 17,163 genomes was built by selecting exactly one genome assembly for each species among the 272,000+ prokaryotic genomes in RefSeq, except for\u00a0E. coli<\/em>\u00a0for which two assemblies were selected as reference.<\/p>\n A total of 497 species are included in this collection for the first time. In addition, comparing to the October 2022 set<\/a>, 174 species are represented by a better assembly and 15 species were removed because of changes in NCBI Taxonomy or uncertainty in their species assignment. The criteria for selecting one assembly for a given species from all assemblies available in RefSeq for the species include assembly contiguity and completeness and quality of the RefSeq annotation. See the documentation<\/a> for details.<\/p>\n We have updated the nucleotide BLAST RefSeq reference genomes database<\/a>\u00a0(fourth in the menu) as well as the database on the\u00a0Microbial Nucleotide BLAST page<\/a>\u00a0to reflect these changes. You can also run\u00a0BLAST searches against the proteins annotated on these reference genomes<\/a> (RefSeq Select proteins database, second in the menu).<\/p>\n","protected":false},"excerpt":{"rendered":" An updated\u00a0bacterial and archaeal reference genome collection\u00a0is available!
