This site presents version 4 of the Fugu genome, released in June 2005 by the International Fugu Genome Consortium. Takifugu rubripes has a very compact genome, with less than 15% consisting of dispersed repetitive sequence, which makes it ideal for gene discovery.
The latest assembly includes 7,213 scaffolds, constituting 390 Mb of the genome, and the mitochondrion. 90% of the genome is on 1118 scaffolds. 74 scaffolds are larger than 1 Mb each and the largest scaffold is 7 Mb. Please refer to the Fugu Project webpage for more details of the sequencing effort.
This is the first full Ensembl genebuild of this genome. It was carried out in an incremental fashion, using fugu proteins initially then adding in other fish, mammal, vertebrate and finally non-vertebrate protein sequences.
General information about this species can be found in Wikipedia.

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, tRNA, scRNA, snlRNA, snoRNA, snRNA, tRNA, 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.
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.
