Nature 496, 498–503 (2013). “This high quality genome is testament to the many scientists who worked on this project and will spur biological research for years to come.”. 25, 3–4 (2000), Vilella, A. J. et al. Article  2). PubMed Central  Our strategy resembled the clone-by-clone sequencing approach adopted previously for both the human and mouse genome projects. The zebrafish genome contains few pseudogenes - genes thought to have lost their function through evolution - compared to the human genome. Compared to the human genome, the zebrafish genome contains few pseudogenes, or genes thought to have lost their function through evolution. a, Exon coverage (blue), stacked with coverage by snRNA exons (black). It has advanced our understanding of muscle and organ development, and been used to verify the causal gene in muscular dystrophy (MD) disorders and the formation of skin cancers. genome – as compared to the human genome – is accepted to originate mainly from a whole-genome duplication dur- ing teleost evolution that was followed by a loss of many Alternatively, the repeat content of the other sequenced teleost species may be under-represented, as these assemblies are mostly WGS16. Nature Genet. recent zebrafish reference genome (GRCz10). Comparison revealed large conserved chromosome segments. Kerstin Howe and Matthew D. Clark: These authors contributed equally to this work. d, Genetic marker placements (red, SATmap markers; blue, heat shock meiotic map markers; black, Massachusetts General Hospital meiotic map markers). This pronounced abundance of type II transposable elements is unique among the sequenced vertebrate genomes, and the genome sequence shows evidence of recently active type II transposable elements. We now have access to an enormous amount of additional research information b, The ohnology relationships between zebrafish chromosomes. and S.P. Essential to this enterprise is a high-quality genome sequence and complete annotation of zebrafish protein-coding genes with identification of their human orthologues. What’s even more impressive is that 84% of human disease genes have … Nature Genet. and B.K. Zebrafish mutations define the functions of hundreds of essential genes in the vertebrate genome. and S.M.J.S. “Our challenge is to develop a comprehensive, functional understanding of all human genes as quickly as possible,” adds Dr. Stemple. 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. We present an effective approach to introduce small nucleotide changes in the zebrafishgenome.Wegeneratedfourdifferentknock-inlinescarrying distinct human cardiovascular-disorder-causing missense mutations a and b were calculated as percentage coverage over 1-Mb overlapping windows (y axis), with a 100-kb shift between each window. 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.

A genetic screen for mutations affecting embryogenesis in zebrafish. This new sequence will be an essential resource to drive the study of genetic function and disease in humans. 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. C.N.-V., G.-J.R. and R.G. Laser injuries were used to induce … K.A., J.W., S.P., J.C., G.T., G.H., G.G., P.H. The dotted line corresponds to differences that are expected once in 100 random genome scans, and the dashed line corresponds to differences expected once in 1,000 random genome scans. Selection of genes expressed in zebrafish microglia/macrophages for further bioinformatics analyses. K.O., B.Z. 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).
