To investigate the number of potential disease-related genes, we compared the list of human genes possessing at least one zebrafish orthologue with the 3,176 genes bearing morbidity descriptions that are listed in the Online Mendelian Inheritance in Man (OMIM) database. Sequence data have been submitted to the BioProject database under accession PRJNA11776. was supported by the National Institutes of Health (NIH) grant R01 GM085318 (to J.H.P. The zebrafish will therefore play an increasingly important role in the future of biomedical research. & Schartl, M. Gene and genome duplications in vertebrates: the one-to-four (-to-eight in fish) rule and the evolution of novel gene functions. 7, e1001357 (2011), Article  The CRISPR/Cas9 methodology works in mice, too, but it is more costly and takes far longer. The second largest orthology class contains human genes that are associated with many zebrafish genes (the ‘one-human-to-many-zebrafish’ class), with an average of 2.28 zebrafish genes for each human gene, and this probably reflects the TSD. Consistent with the conservation of synteny, chromosome 16 and chromosome 19 possess clusters of orthologues of genes associated with the mammalian major histocompatibility complex (MHC) as well as the hoxab and hoxaa clusters, respectively, which are each orthologous to the human HOXA cluster25. Furthermore, this cohort constitutes the genes and loci that acquire DNAme during development (i.e., ZGA to muscle). According to the annotation of the transcripts at the time of manuscript preparation, these represent 10,318 genes, providing approximately 45% coverage of the zebrafish genome. The long-term goal is the creation of a knockout allele in every protein-coding gene in the zebrafish genome. Genes shared across species are considered in terms of copies at the time of the split. Z.N. c and d were calculated over 100-kb windows. You are using a browser version with limited support for CSS. Importantly for disease studies, comparison between human and zebrafish sequences reveals that 70% of human genes have at least one obvious zebrafish orthologue. The Zebrafish Information Network (ZFIN) is the database of genetic and genomic data for the zebrafish (Danio rerio) as a model organism.ZFIN provides a wide array of expertly curated, organized and cross-referenced zebrafish research data. A second paper reports on an ongoing effort to identify and phenotype disruptive mutations in every zebrafish protein-coding gene. Interestingly, publication of the first paper on zebrafish development (Roosen, 1937) investigated the effect of different toxins, alcohol, and different levels of carbohydrate or fat diets on zebrafish embryos, larvae, and adult developmental stages. b, The ohnology relationships between zebrafish chromosomes. 44, 581–585 (2012), Collins, J. E., White, S., Searle, S. M. & Stemple, D. L. Incorporating RNA-seq data into the zebrafish Ensembl genebuild. In an effort to provide a rapid and robust tool for zebrafish gene mapping, a panel of radiation hybrids (RH) was produced by fusion of irradiated zebrafish AB9 cells with mouse B78 cells. All other sequenced teleost fish exhibit a much lower repeat content, with an average of less than 30%. To generate SATmap we took advantage of the fact that it is possible to create double haploid individuals that contain only maternally derived DNA, that are homozygous at every locus and that can be raised until they are fertile22 (Fig. We generated cloned libraries of large fragments of genomic DNA, assembled a physical map of large-insert clones and completely sequenced a set of minimally overlapping clones. 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. produced the SATmap. Development 123, 37–46 (1996), CAS  CAS  We chose Tübingen as the zebrafish reference strain as it had been used extensively to identify mutations affecting embryogenesis2. Loss-of-function mutations in the zebrafish ache gene therefore generate animals that are completely devoid of ACh-hydrolyzing activity (Behra et al., 2002). We thank the zebrafish information network (ZFIN) for funding part of the manual annotation of the zebrafish genome and the ZFIN staff for support with gene nomenclature and other genome issues. Thus, zebrafish achieve a totipotent chromatin state at ZGA through paternal genome competency and maternal genome DNAme reprogramming. Development 123, 1–36 (1996), Golzio, C. et al. Nature Genet. LSHG-CT-2003-503496, ZF-MODELS) and Seventh Framework Programme (grant no. Humans and zebrafish share 70 percent of the same genes and 84 percent of human genes known to be associated with human disease have a counterpart in zebrafish. It is possible that zebrafish proteins with functionally similar activities to LIF, OSM and IL-6 exist, but that their sequence divergence is so great that they cannot be recognized as orthologues. Nature 496, 498–503 (2013). Using DCS blocks, we identified zebrafish paralogous genes that are part of DCS blocks and consistent with the locally alternating chromosomes, hence with an origin at the TSD. This number of SNPs between just two homozygous zebrafish individuals is far in excess of that seen between any two humans and is nearly one-fifth of all SNPs measured among 1,092 human diploid genomes29. Nature 491, 56–65 (2012), Krzywinski, M. et al. Although the main focus of zebrafish research has traditionally been on developmental biology, keeping and observing zebrafish in the lab led to the identification of diseases similar to humans, such as cancer, which subsequently became a subject for study. & Postlethwait, J. H. Genome evolution and meiotic maps by massively parallel DNA sequencing: spotted gar, an outgroup for the teleost genome duplication. and K.M. Article  Nature 378, 150–157 (1995), Gritsman, K. et al. was supported by the German Human Genome Project (DHGP Grant 01 KW 9627 and 01 KW 9919). and Y.G. The number of protein-coding genes among vertebrates is relatively stable, although even closely related species may show great disparities in the nature of their protein-coding gene content. Derek L. Stemple. To obtain evidence for a more complete description of protein-coding genes, we used high-throughput short-read complementary DNA sequencing and obtained a deep-coverage data set for messenger RNAs expressed in zebrafish at various stages of development and in adult tissues6. Detailed descriptions of all the methods used for this project are available in the Supplementary Information. Marker placements have been normalized so that the maps can be compared. K.A., J.W., S.P., J.C., G.T., G.H., G.G., P.H. We identified double-conserved synteny (DCS) blocks between all sequenced tetrapods and four fish genomes (zebrafish, medaka, stickleback and Tetraodon). Cell 148, 434–446 (2012), Amores, A., Catchen, J., Ferrara, A., Fontenot, Q. Our strategy resembled the clone-by-clone sequencing approach adopted previously for both the human and mouse genome projects. Zebrafish is the only peer-reviewed journal dedicated to the central role of zebrafish and other aquarium species as models for the study of vertebrate development, evolution, toxicology, and human disease.. Due to its prolific reproduction and the external development of the transparent embryo, the zebrafish is a prime model for genetic and developmental studies.

Since the earliest whole-genome shotgun-only assembly became public in 2002, the zebrafish reference genome sequence has enabled many new discoveries to be made, in particular the positional cloning of hundreds of genes from mutations affecting embryogenesis, behaviour, physiology, and health and disease. This latest assembly has been refined by the addition of nearly 1000 finished clone sequences and the resolution of more than 400 genome issues. The image was produced using Circos30. Abstract. Homozygotes for the Tübingen (grandmaternal) allele had a very high probability of being female, whereas homozygotes for the AB (grandpaternal) allele were very unlikely to be female (Fig. Such investigations have also contributed notably to our understanding of basic vertebrate biology and vertebrate development.
