The project was supported by the Consortium National de Recherche en Genomique and the National Human Genome Research Institute.
The genome assembly was performed using Arachne (Jaffe D.B. et. al. 2003. Gen. Res. 13, 91-96). This site presents version 7 of the assembly.
Genes were annotated by Genoscope, combining evidence from Geneid, Genscan, Genewise and Exofish predictions with alignments of Tetraodon cDNAs to the genome. This was done automatically using GAZE (Howe K., Chothia T. and Durbin R. 2002. Gen. Res. 12, 1418-27) with a custom-designed configuration and gene structure model.
The annotation also includes 87 manually curated structures of a number of HOX and Cytokine genes.
General information about this species can be found in Wikipedia.
|Assembly||TETRAODON 8.0, Mar 2007|
|Golden Path Length|
The golden path is the length of the reference assembly. It consists of the sum of all top-level sequences in the seq_region table, omitting any redundant regions such as haplotypes and PARs (pseudoautosomal regions).

Genes and/or transcript that contains an open reading frame (ORF).
|Small non coding genes|
Small non coding genes are usually fewer than 200 bases long. They may be transcribed but are not translated. In Ensembl, genes with the following biotypes are classed as small non coding genes: miRNA, miscRNA, rRNA, scRNA, snlRNA, snoRNA, snRNA, and also the pseudogenic form of these biotypes. The majority of the small non coding genes in Ensembl are annotated automatically by our ncRNA pipeline. Please note that tRNAs are annotated separately using tRNAscan. tRNAs are included as 'simple fetaures', not genes, because they are not annotated using aligned sequence evidence.
A pseudogene shares an evolutionary history with a functional protein-coding gene but it has been mutated through evolution to contain frameshift and/or stop codon(s) that disrupt the open reading frame.
