This number of ancestral genes retained as duplicates in zebrafish is higher, both in absolute number and in proportion, than in other fish genomes (chi-squared test, all P < 3 × 10−5). Circos: an information aesthetic for comparative genomics. Nature 485, 363–367 (2012), ADS  14, 1–10 (2004), MathSciNet  c, Sequence composition (grey bars, clones; blue bars, WGS contigs). Abstract. By continuing you agree to the use of cookies. 15). Although most chromosomes showed no significant genetic bias for a particular sex, we found that most of chromosome 16 carried a strong signal (P = 9.1 × 10−7) with a broad peak around the centromere (Fig. Roles of brca2 (fancd1) in oocyte nuclear architecture, gametogenesis, gonad tumors, and genome stability in zebrafish. 2). In 2008, together with the Wolfe Lab, we were among the first two groups to demonstrate the application of programmable nucleases for introducing targeted deletions into the zebrafish germline. Our meiotic map, SATmap, which was generated to anchor the genomic sequence, provided an opportunity to examine whether there are any strong signals for sex determination. Previous assemblies were produced by M.C., who developed the first assembly integration process, and by S.R., T.E. PLoS Genet. produced the WGS31 assembly. Article  PubMed Google Scholar. In fact, 110 genes (out of 663) have no identifiable orthologues in any other sequenced teleost genome and indeed seem to be zebrafish-specific genes. produced the SATmap. Automated annotation (Ensembl) was provided by J.E.C., S.W., J.-H.V., S.T. A circular representation of ohnologue pairs (Fig. Several zebrafish linkage groups have conserved syntenies with multiple human chromosomes, an observation that we consider in detail in the accompanying paper (Postlethwait et al. 19, 327–335 (2009), Rodríguez-Mari, A. et al. 1 and Supplementary Fig. The grey line at 0.5 corresponds to expectation for heterozygotes (solid lines) and the grey line at 0.25 corresponds to expectation for homozygotes (dashed and dotted lines). Aptly named and tiny in stature, the paper-clip sized zebrafish might fool you into thinking it hasn't much to offer. The CRISPR/Cas9 methodology works in mice, too, but it is more costly and takes far longer. and Y.G. We identified double-conserved synteny (DCS) blocks between all sequenced tetrapods and four fish genomes (zebrafish, medaka, stickleback and Tetraodon). 22, 2067–2078 (2012), Talbot, W. S. et al. 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. and K.M. In the present paper, ... Our investigation has shown that the zebrafish genome has twice the number of NR5A genes as the human genome, and that the developmental genetic functions of these genes, as reflected by their expression patterns, are different between ray-fin (zebrafish) and lobe-fin (human) lineages. Indeed, 2.3 million instances of type II DNA transposable elements cover 39% of the zebrafish genome sequence (Supplementary Table 12), whereas type II repeats cover only 3.2% of the human genome. casper has been a widely used transparent mutant of zebrafish. Similarly, the zebrafish genome has no BRCA1 orthologue, but does have an orthologue of the BRCA1-associated BARD1 gene, which encodes an associated and functionally similar protein and a brca2 gene, which plays an important role in oocyte development, probably reflecting its role in DNA damage repair15. are involved in the ongoing improvement of the zebrafish genome assembly. and R01 OD011116 (later changed to R01 RR020833) (to J.H.P.). was supported by the German Research Foundation (DFG Grant NU 22/5). The position of ohnologous genes between chromosomes are linked in grey (for clarity, links between chromosomes that share less than 20 ohnologues have been omitted). The light grey shaded box corresponds to the region in which empirical P < 0.01, the dark grey shaded box corresponds to the region in which P < 0.001. The systematic application of genetic screens led to the phenotypic characterization of a large collection of mutations1,2. Genome Res. Unexpectedly, the DNA of many oocyte genes important for germline functions (i.e., piwil1) or early development (i.e., hox genes) is methylated, but the loci are demethylated during zygotic cleavage stages to precisely the state observed in sperm, even in parthenogenetic embryos lacking a replicating paternal genome. C.N.-V., G.-J.R. and R.G. The long arm of chromosome 4 also has a special structure with respect to gene orthology and synteny. and J.Y. These mutations, when driven to homozygosity, can produce defects in a variety of organ systems with pathologies similar to human disease.

Zebrafish are members of the teleostei infraclass, a monophyletic group that is thought to have arisen approximately 340 million years ago from a common ancestor11. To investigate the interesting finding that SATmap F1 fish could be either male or female while being genetically identical and heterozygous at every polymorphic locus, we sought a genetic signal for sex determination in the F2 generation, in which these polymorphisms segregate. Nature | Sperm chromatin patterns mirror the blastomere at zygotic genome activation (ZGA), Maternal chromatin patterns are reprogrammed to the paternal/sperm state by ZGA, Maternal reprogrammed/demethylated genes are all later methylated in development, Promoter DNA methylation prevents precocious expression of particular genes at ZGA. R.G. The x axis shows the chromosomal position in Mb. Essential to this enterprise is a high-quality genome sequence and complete annotation of zebrafish protein-coding genes with identification of their human orthologues. The zebrafish (Danio rerio) was first identified as a genetically tractable organism in the 1980s. 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. Multiple sex-associated regions and a putative sex chromosome in zebrafish revealed by RAD mapping and population genomics. The image was produced using Circos30. A genetic screen for mutations affecting embryogenesis in zebrafish. Genes shared across species are considered in terms of copies at the time of the split. Curr. Genetically identical, heterozygous F1 fish of both sexes resulted from crossing the founders.

Correspondence to generated and provided clone libraries. In general, zebrafish ohnologous pairs are enriched in specific functions (neural activity, transcription factors) and are orthologous to mammalian genes under stronger evolutionary constraint than genes that have lost their second copy. Nature 442, 688–691 (2006), Tobin, D. M. et al. The F1 individuals were crossed to generate a panel of F2 individuals, each with its own unique set of meiotic recombinations between AB and Tübingen (Tü) chromosomes, which were uncovered by dense genotyping with a set of 140,306 SNPs covering most of the genome.

We would like to acknowledge the support of the European Commission's Sixth Framework Programme (contract no. The zebrafish has developed into an important model organism for biomedical research over the last decades. We carried out a four-way comparison between the proteome of two mammals (human and mouse), a bird (chicken) and the zebrafish to quantify the fraction of shared and species-specific genes present in each genome (Fig. The long arm of chromosome 4 is unique among zebrafish genomic regions, owing to its relative lack of protein-coding genes and its extensive heterochromatin. Google Scholar, Panizzi, J. R. et al. The results demonstrated that using the CRISPR/Cas9 technique in zebrafish will make it possible to both generate mutants for all genes in the zebrafish genome and carry out large-scale phenotyping, they noted in the Genome Research paper. The long-term goal is the creation of a knockout allele in every protein-coding gene in the zebrafish genome. To investigate non-CG methylation further, the researchers conducted a comprehensive profiling of the zebrafish genome, a vertebrate organism that is a distant evolutionary relative of humans and shares 70% of our genes, which makes it a useful model for studying the effects of human genes. The clone and WGS sequence is tied to a high-resolution, high-density meiotic map called the Sanger AB Tübingen map (SATmap), named after the strains of zebrafish used to make the map (Supplementary Information).

Researchers at the Garvan Institute of Medical Research have uncovered a new form of DNA modification in the genome of zebrafish, a vertebrate animal that … and S.P. Sequence-specific nucleases like TALENs and the CRISPR/Cas9 system have greatly expanded the genome editing possibilities in model organisms such as zebrafish. An SNP-based linkage map for zebrafish reveals sex determination loci. The notable excess observed in zebrafish may be a consequence of the WGD, because pairs of duplicated genes that arose from the WGD, but with no orthologue in amniotes, are counted as two specific genes. The closest vertebrate species in terms of the abundance of type II transposable elements is Xenopus tropicalis (25% type II transposable elements), whereas the sequenced and annotated teleost fish (the pufferfish Takifugu and Tetraodon, the three-spined stickleback (Gasterosteus aculeatus) and the medaka (Oryzias latipes)) each possess type II transposable element coverage of less than 10%, which may relate to the fact that the zebrafish genome diverges basally from the other sequenced and annotated teleost genomes17. (2021), Journal of Toxicology and Environmental Health, Part A A paper published last month in Nature unveiled the long-awaited sequence of the zebrafish genome, revealing that zebrafish, mice and human have 12,719 genes in … Early vertebrate embryos must achieve totipotency and prepare for zygotic genome activation (ZGA). Zebrafish (Danio rerio) has been a prominent model vertebrate in a variety of biological disciplines.Substantial information gathered from developmental and genetic research, together with near-completion of the zebrafish genome project, has placed zebrafish in an attractive position for use as a toxicological model. J. Exp. In addition, in a specific group of zebrafish derived recently from a natural population, the subtelomeric region of the long arm of chromosome 4 has been found to contain a major sex determinant with alleles that are 100% predictive of male development and 85% predictive of female development, suggesting that this chromosome may be, might have been, or may be becoming, a sex chromosome in this particular population20. Nature 428, 617–624 (2004), Jaillon, O. et al. and C.Lang. 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. Direct assignment of function on the basis of this information would be facilitated by the development of a rapid, targeted ‘knockdown’ technology in this model vertebrate. Nature 491, 56–65 (2012), Krzywinski, M. et al. 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. Similar graphs for the other chromosome are provided in the Supplementary Information. Furthermore, this cohort constitutes the genes and loci that acquire DNAme during development (i.e., ZGA to muscle). We chose Tübingen as the zebrafish reference strain as it had been used extensively to identify mutations affecting embryogenesis2. In addition, we generated WGS sequences by end-sequencing a mixture of large- and short-insert libraries. All mutant alleles and data are freely available at Nature (in the press), Varshney, G. K. et al. PubMed  Although the zebrafish reference genome sequencing is complete, a few poorly assembled regions remain, which are being resolved by the Genome Reference Consortium ( It is unclear whether these genes have been lost along the evolutionary branch leading to the chicken, or whether this is due to annotation or orthology assignation errors in the chicken genome. Remove embryos from their chorions in batches of ~100 by placing in 1 mg/ml of pronase and swirling occasionally (5-10 minutes for 24 h embryos, 10-20 minutes for 3 day embryos). Internet Explorer). This result suggests that the evolutionary path leading to the zebrafish experienced an expansion of repeats, possibly facilitated by a population bottleneck. Among zebrafish chromosomes, chromosome 16 and chromosome 19 are unique in their one-to-one conservation of synteny.
