New ribosomal RNA BLAST databases available on the web BLAST service and for download

We have a curated set of ribosomal RNA (rRNA)  reference sequences (Targeted Loci) with verifiable organism sources and current names. This set is critical for correctly identifying and classifying prokaryotic (bacteria and archaea) and fungal samples (Table 1). To provide easy access to these sequences, we recently added a separate rRNA/ITS databases section on the nucleotide BLAST page for these targeted sequences that makes it convenient to quickly identify source organisms (Figure 1)

Important changes coming to prokaryotic Reference and Representative genome assemblies

We are making changes to the set of bacterial and archaeal RefSeq Reference and Representative assemblies in February 2020.

  • We will reduce the number of Reference assemblies to 15 that have annotation provided by outside experts (Table 1) and re-annotate the 105 other current Reference assemblies using the latest Prokaryotic Genome Annotation Pipeline (PGAP) software. The re-annotated assemblies will lose reference status.
  • We will reassess and revise the set of Representative assemblies so that there is one assembly per species to better reflect the taxonomic diversity of the RefSeq bacterial and archaeal assemblies.

Important changes to the genomes FTP site in February

We have added the latest NCBI Eukaryotic Genome Annotation Pipeline results for the more than 580 species that we annotate to the genomes/refseq directory on the genomes FTP area. As we announced in December, we will stop publishing annotation results to the genus_species directories (example: genomes/Xenopus_tropicalis) on the genomes FTP site effective February 1, 2020. We will also move existing genus_species directories to genomes/archive/old_refseq during the month of February.X_t_assemblyFigure 1. The Assembly page for the Xenopus tropicalis UCB Xtro 10.0 (GCF_000004195.4) showing the blue download button. Annotation results such as the RefSeq transcript alignments that can be downloaded from the web page are now also under the genomes/refseq directory on the FTP site. The FTP path to the .bam alignment files is in red.

These FTP changes do not affect the Assembly download function. As always, you can download assembly data using the blue Download button on the web pages (Figure 1).

Special announcements:

1. New Mus musculus (house mouse) Annotation Release 108

The latest annotation run for Mus musculus, 108, is a complete re-annotation of the mouse GRCm38.p6 assembly that incorporates ongoing curation work and new computed models based on extensive long-read transcriptome data.
See the annotation report for  details.  You can access these  annotation products through the sequence databases and on the FTP site.

2. Updated Homo sapiens Annotation Release 109.20190905

Annotation Release 109.20190905 is an update of NCBI Homo sapiens Annotation Release 109. The annotation report has details. You can access the annotation products from the sequence databases or download the data from the FTP site. We will continue to update the human genome annotation frequently so that we can
incorporate ongoing curation work including the MANE project and other curation activities. See our post on the increased frequency of annotation for more information on the new schedule.

3. dbSNP Human Build 153

The short variations (SNPs) annotated on human RefSeq transcripts and RefSeqGene records now incorporate data from dbSNP build 153.
