WormBase updates in WS277 – new protein schematic images!

We have released the 277th version of WormBase! As always, for a detailed report please look at the WS277 release notes.

New features: We’ve updated the protein schematic image in the homology widget on protein pages (see, for example, the UNC-2, isoform a page.) This image displays protein domains and exons mapped to amino acid coordinates, making it easy to see which regions of a transcript correspond to specific features. Driven by JBrowse — the genome browser at WormBase — users can click through the image to an interactive view in amino acid coordinates. From that familiar interface, one can scroll, export sequence (can they?), get additional information on specific features, and zoom in to single amino acid residue resolution, color-coded by chemical property.  The previous static protein schematic image remains available by clicking on the “Legacy Protein Schematics” link, but will be removed after the WS278 release.

New data sets:

C. elegans: Additional Nanopore transcript data has been added.

C. elegans VC20210: The VC2010 strain data includes gene annotation which has been manually curated to improve the coding gene structures lifted over from the N2 strain annotation. This process is substantially complete, with some work still to be done on chromosome X. The number of coding genes which do not map correctly has been reduced so far from around 400 down to 50 genes which cannot yet be located and 10 which appear to be pseudogenes in VC2010. There are 20 genes which appear to be duplicated in N2 and have disappeared in VC2010. There have been 39 novel coding genes created.


Alliance of Genome Resources 3.1 released

The Alliance of Genome Resources is a portal for data related to six of the major model organisms and human data. The Alliance has been updated to the 3.1 release and contains new features and new data. Key new features include a refined home page and an allele page that includes transgenic alleles and shows variant consequences for transcripts. The Alliance also provides a Java API for access to the data. For a complete list of 3.1 features please see the release notes.

WormBase updated to WS276

A new release of WormBase, WS276 is live on the website. Please see the release notes which contain complete information about this release.

Data changes: note that C. elegans gene descriptions in the “Overview” section of gene pages have improved orthology statements to human genes. WormBase uses the DIOPT orthology data from the Alliance of Genome Resources and has increased stringency by displaying only those human orthologs that have been determined by three or more methods. This should significantly improve the orthology data in WormBase which is also reflected in the gene descriptions. 

Known Issues: the circRNAs failed mapping so sequence and genomic position are not available for this release, but will be in the WS277 release.

WormBase version WS274 released

Please note that WormBase version WS274 was released and is the current release now live on the website. The version of the C. elegans reference genome in this release is WBcel235, included since WS235.

Highlights of this release include:

  1. Isoseq data which was presented at the PacBioNorth America User Group meeting. We applied the PacBio post processing pipeline as described here. The resulting sequences are including in the transcript alignments and will be visible on the genome browser. They will also be included in our automatic transcript generation pipeline in a future release of WormBase.
  2. Improved code to generate non-redundant transcripts. Each CDS should now have only unique transcripts.
  3. Improved interaction data display in the Interactions widget: New Venn diagram for the different types of interactions-physical, genetic and regulatory.

WS273 version of WormBase

Please note that the WS273 version of WormBase is live on our website.  The release notes for this version contain a detailed report of the various entities (eg. gene, allele) and the number of sequence and biological annotations.

Some of the highlights are:

C.elegans Nanopore data has been integrated and is being used to improve UTR annotation. Further work on improving our automatic transcript annotation is ongoing.

This release includes a few hundred gene splits in Pristionchus pacificus predicted by the Sommer lab based on IsoSeq analysis. More will be included in future releases.
