Announcing the RefSeq annotation of sheep ARS-UI_Ramb_v2.0!

Announcing the RefSeq annotation of sheep ARS-UI_Ramb_v2.0!

The new reference assembly for sheep is now annotated! Assembly ARS-UI_Ramb_v2.0 is made of 142 scaffolds, a drop from 2,640 in the 2017 assembly Oar_rambouillet_v1.0. With a contig N50 of 43 Mb, ARS-UI_Ramb_v2.0 is 15 times more contiguous than the first assembly of the Rambouillet breed.

Annotation Release 104 (AR 104) of ARS-UI_Ramb_v2.0 reflects these improvements. Nearly 200 more coding genes have a 1:1 ortholog in the human genome than in the annotation of Oar_rambouillet_v1.0 (AR 103). The number of coding models annotated as partial is down 35% from 165 to 107, and the number of coding models labeled low quality due to suspected indels or base substitutions in the underlying genomic sequence decreased by 51% (1646 to 796). Based on BUSCO analysis, 99.1% of the models (cetartiodactyla_odb10) are complete in AR 104 versus 98.8% in AR 103. Details of this annotation, including statistics on the annotation products, the input data used in the pipeline and intermediate alignment results, can be found here.

Announcing the re-annotation of RefSeq genome assemblies for E. coli and four other species!

We have re-annotated all RefSeq genomes for Escherichia coliMycobacterium tuberculosis, Bacillus subtilis, Acinetobacter pittii, and Campylobacter jejuni using the most recent release of PGAP. You will find that more genes now have gene symbols (e.g. recA). Your feedback indicated that the lack of symbols was an impediment to comparative analysis, so we hope that this improvement will help.

The number of re-annotated genomes is 25,619 for E. coli, 470 for B. subtilis, 6,828 for M. tuberculosis, 316 for A. pittii, and 1,829 for C. jejuni. On average, the increase in gene symbols is 30% in E. coli, 110% in B. subtilis, 57% in M. tuberculosis, 94% in A. pittii and 62% in C. jejuni (see Figure 1). After re-annotation, on average, 73% of PGAP-annotated E. coli genes and 79% of B. subtilis have symbols (35% for M. tuberculosis, 40% for A. pittii and 46% for C. jejuni). We assigned symbols to the annotated genes by calculating the orthologs between the genome of interest and the reference assembly for the species, and transferring the symbols from the reference genes to their orthologs in the annotated genomes.

Figure 1: Average and standard deviation of the number of genes annotated with symbols per genome, in the previous (blue) and the current annotation (orange).

NCBI at CSHL Biology of Genomes, May 11 – 14, 2021

NCBI at CSHL Biology of Genomes, May 11 – 14, 2021

NCBI staff will be presenting virtual posters at the Cold Spring Harbor Laboratory  Biology of Genomes Meeting, May 11 -14, 2021. The posters will cover the following topics: 1) a cloud-ready suite of tools (PGAP, RAPT , and SKESA) for assembling and annotating prokaryotic genomes,  2) Datasets — a new set of services for downloading genome assemblies and annotations, and 3) updates on NCBI RefSeq eukaryotic genome annotation, and the Genome Data Viewer (GDV). Read more below for the full abstracts.

The virtual poster gallery opens Tuesday, May 11 at 9:00 a.m. with dedicated time for poster viewing and discussion at 1:00 to 2:00 p.m. through Slack each day. The poster gallery will be open for entire the conference and remain available for six weeks afterwards.  Continue reading “NCBI at CSHL Biology of Genomes, May 11 – 14, 2021”
