About the C.savignyi genome

Assembly

The genome of a single Ciona savignyi from San Francisco Bay was shotgun-sequenced by the Broad Institute and assembled using Arachne2. The Sidow lab at Stanford used this as a basis for the assembly [details].

The assembly consists of 374 Reftigs, totalling 174 Megabases, with a Contig N50 of 141Kb and Reftig N50 size of 1800Kb.

Annotation

The standard Ensembl mammalian pipeline was modified for annotation of the Ciona savignyi genome, owing to the lack of genomic information from closely-related species. Thus, in addition to aligning known Ciona proteins to the sequence (as per the standard pipeline), we aligned Ciona-specific cDNA and EST sequences against the genome, and then used these in conjunction with protein data from other species to build additional gene models.

What's New in Ensembl 50

Ciona savignyi News

• Non-coding genes
  These have been updated for most species, including an miRNA update and HGNC names where possible.

General News

• Canonical Transcripts
  

  Canonical transcripts have been defined for all genes in the core databases.

• SSAHA
  From release 50 we will no longer be providing SSAHA sequence search. If you wish to run your own SSAHA sequence search you can download the files to generate the search hashes from our FTP site.
• Projections of gene names and GO terms
  These have been done as usual, between a variety of species.
• Stored peptide stats
  In order to improve efficiency on ProtView, peptide statistics are now calculated in advance and stored as translation attributes, instead of being calculated on the fly.
