Venturing beyond the genes: New RefSeq Functional Elements publication!

If you’re curious about genome annotation beyond the genes, then read on! We previously blogged about our RefSeq Functional Elements resource, which provides annotation of experimentally validated, non-genic functional elements in human and mouse. Now, to kick off 2022, we’re delighted to announce a new publication in the January issue of Genome Research:

Farrell CM, Goldfarb T, Rangwala SH, Astashyn A, Ermolaeva OD, Hem V, Katz KS, Kodali VK, Ludwig F, Wallin CL, Pruitt KD, Murphy TD. RefSeq Functional Elements as experimentally assayed nongenic reference standards and functional interactions in human and mouse. Genome Res. 2022 Jan;32(1):175-188. doi: 10.1101/gr.275819.121. Epub 2021 Dec 7. PMID: 34876495.

Introducing the NIH Comparative Genomics Resource (CGR)

NCBI is looking forward to seeing you in person at the International Plant and Animal Genome Conference (PAG XXIX), January 8-12, 2022 in San Diego, California. We’re especially excited to introduce our newest endeavor – the NLM initiative known as the NIH Comparative Genomics Resource (CGR)– a platform we are developing to support comparative analyses of sequenced eukaryotic research organisms. Understanding and supporting the needs of researchers is a fundamental element in the development of CGR and is critical to its future success in supporting a large and diverse collection.

Please join NCBI for the following events to learn more about CGR and how you can inform its development:

New NCBI Gene Ensembl Comparison Expansion

NCBI Gene has added Ensembl Rapid Releases to the calculation of matching annotations between NCBI RefSeq and Ensembl. This has resulted in the inclusion of over 60 additional assemblies for a total of 241 organisms represented in the set. Matches are made based on transcript and CDS comparisons, and Ensembl gene, transcript, and protein identifiers for annotations similar to the NCBI RefSeq annotations are reported in NCBI Gene and in the gene2ensembl file on the Gene FTP site. The Ensembl annotation is also available in the graphical view and in NCBI’s Genome Data Viewer to give you a side-by-side view of how the annotations compare. Check out blue whale E2F1 for an example.

Updated prokaryotic representative genome collection

The bacterial and archaeal representative genome collection has been updated!  We selected a total of 14,912 of the 224,000 prokaryotic RefSeq assemblies to represent their respective species. The collection has grown by 8% since April 2021 and now includes Candidatus and endosymbiont species (Figure 1), which constitute 303 and 140 respectively of the 1,077 newly added species. In addition, 719 species are represented by a better assembly, and 70 species were removed because of changes in NCBI Taxonomy or uncertainty in their species assignment.

NCBI Presentations at Biodiversity Genomics 2021 Highlight Growing Support for Comparative Genomics

NCBI Presentations at Biodiversity Genomics 2021 Highlight Growing Support for Comparative Genomics

The National Center for Biotechnology Information (NCBI) has several speakers at the upcoming Biodiversity Genomics Conference from September 27 to October 1, 2021.

Valerie Schneider, head of NCBI’s SeqPlus Program and Deputy Director for Sequence Offerings, will present a poster discussing how NCBI’s new comparative genome research focus will enable researchers to explore all eukaryotic research organisms, find related organisms and support additional organism-specific resources that a specific community may have or wish to develop.

Nuala O’Leary, Product Owner, NCBI Datasets will present the latest developments for Datasets, a beta resource that supports intuitive and flexible access to genome data for a broad range of taxa via a redesigned website and command-line tools.

Adelaide Rhodes, Cloud Subject Matter Expert in Education, will present two case studies that emphasize the ease of navigating the new Datasets website as well as the use of command line tools to speed up data discovery for genes and genomes of interest.

Terence Murphy, Product Owner, NCBI RefSeq will present a new tool for genome providers to identify contamination in newly assembled sequences with high sensitivity, specificity, and performance.

The Biodiversity Genomics Conference brings together a global audience to celebrate achievements in genome sequencing across the eukaryotic tree of life, explore current challenges and solutions, and to develop strategies for sequencing and data sharing in the upcoming decade of biodiversity genomics. NCBI has several programs that support the needs of this scientific research group.

Fungal Disease Awareness Week: fungal pathogen data and literature at NCBI

Fungal Disease Awareness Week: fungal pathogen data and literature at NCBI

This post is in support of the CDC’s Fungal Disease Awareness Week — September 20-24, 2021.

The impact of fungal diseases on human health has often been neglected, but increased association of fungal infections with severe illness and death during the COVID-19 pandemic has brought fungal diseases into the spotlight.

According to the CDC, the most common fungal co-infections in patients with COVID-19 include aspergillosis or invasive candidiasis including healthcare-associated infection from Candida auris.  Other reported diseases are mucormycosis, coccidioidomycosis and cryptococcosis. Aspergillosis is commonly caused by Aspergillus fumigatus, mucormycosis by Rhizopus species, coccidioidomycosis by Coccidioides immitis and C. posadasii and cryptococcosis by Cryptococcus neoformans.

This post explores several NCBI resources that have relevant information about the fungal pathogens implicated in these COVID-19 related illnesses.

Assembled genomes

Correctly identified and annotated genome assemblies are available for the fungal taxa implicated as co-infections in COVID-19 patients are summarized in table below.  These and  many other fungi are also available as curated RefSeq genome assemblies.
