Abstract

A high-quality sequence assembly of the zebrafish genome reveals the largest gene set of any vertebrate and provides information on key genomic features, and comparison to the human reference genome shows that approximately 70% of human protein-coding genes have at least one clear zebrafish orthologue. The genome of the zebrafish — a key model organism for the study of development and human disease — has now been sequenced and published as a well-annotated reference genome. Zebrafish turns out to have the largest gene set of any vertebrate so far sequenced, and few pseudogenes. Importantly for disease studies, comparison between human and zebrafish sequences reveals that 70% of human genes have at least one obvious zebrafish orthologue. A second paper reports on an ongoing effort to identify and phenotype disruptive mutations in every zebrafish protein-coding gene. Using the reference genome sequence along with high-throughput sequencing and efficient chemical mutagenesis, the project's initial results — covering 38% of all known protein-coding genes — they describe phenotypic consequences of more than 1,000 alleles. The long-term goal is the creation of a knockout allele in every protein-coding gene in the zebrafish genome. All mutant alleles and data are freely available at go.nature.com/en6mos . Zebrafish have become a popular organism for the study of vertebrate gene function1,2. The virtually transparent embryos of this species, and the ability to accelerate genetic studies by gene knockdown or overexpression, have led to the widespread use of zebrafish in the detailed investigation of vertebrate gene function and increasingly, the study of human genetic disease3,4,5. However, for effective modelling of human genetic disease it is important to understand the extent to which zebrafish genes and gene structures are related to orthologous human genes. To examine this, we generated a high-quality sequence assembly of the zebrafish genome, made up of an overlapping set of completely sequenced large-insert clones that were ordered and oriented using a high-resolution high-density meiotic map. Detailed automatic and manual annotation provides evidence of more than 26,000 protein-coding genes6, the largest gene set of any vertebrate so far sequenced. Comparison to the human reference genome shows that approximately 70% of human genes have at least one obvious zebrafish orthologue. In addition, the high quality of this genome assembly provides a clearer understanding of key genomic features such as a unique repeat content, a scarcity of pseudogenes, an enrichment of zebrafish-specific genes on chromosome 4 and chromosomal regions that influence sex determination.

  • The number of sites of crucial functional importance may be unexpectedly constant across taxa, despite differences in the number of genes and the length of coding regions.

    “our finding highlights another aspect: the number of sites of crucial functional importance may be unexpectedly constant across taxa, despite the differences in the number of genes and the length of the coding regions (Alexander et al. 2010; Howe et al. 2013).”

    From An Estimate of the Average Number of Recessive Lethal Mutations Carried by Humans (2015) · cites this paper as Howe et al. 2013

    In the comparative-genomics passage (labeled Abstract; page unavailable), Howe et al. report a relatively stable number of protein-coding genes among vertebrates and a shared core that probably approximates an essential set. The paper does not establish that the number of crucial functional sites is constant across taxa, or relate such a count to differences in coding-region length. (LLM, conf=0.86)

  • Approximately 82% of human disease-related genes have at least one zebrafish orthologue.

    “Zebrafish have become an effective and popular model organism for drug screening, drug efficacy evaluation, and dissecting molecular mechanisms of drug action, as approximately 82% of human disease-related genes have at least one zebrafish orthologue [39].”
  • A high-quality genome and a common SNP VCF file are available for zebrafish.

    “Two useful resources for applying SNP-based demultiplexing are available for zebrafish, a high-quality genome (Howe et al, 2013), and a common SNP variant, variant call format (VCF) file for the species (LaFave et al, 2014).”
  • The predicted genome size of Danionella translucida is around one half of the zebrafish reference genome.

    “The predicted genome size of DT is around one half of the zebrafish reference genome33.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
