Google Scholar, Amores, A. et al. 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). Loss-of-function mutations in the zebrafish ache gene therefore generate animals that are completely devoid of ACh-hydrolyzing activity (Behra et al., 2002). 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. 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.

Gene duplicates that result from this process are called ohnologues (after Susumu Ohno who suggested this mechanism of gene duplication)13. For example, a gene that exists in one copy in zebrafish but has been duplicated in the human lineage will be counted as only one shared gene in the overlap. 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). Sequence data have been submitted to the BioProject database under accession PRJNA11776. 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. Zebrafish possess 26,206 protein-coding genes6, more than any previously sequenced vertebrate, and they have a higher number of species-specific genes in their genome than do human, mouse or chicken. a and b were calculated as percentage coverage over 1-Mb overlapping windows (y axis), with a 100-kb shift between each window. Zebrafish is a peer-reviewed journal focusing on research using zebrafish and other aquarium species including medaka, Fugu, and Xiphophorus as models for studies of vertebrate development, toxicology, and human disease. Although its contributions have already been substantial, zebrafish research holds further promise to enhance our understanding of the detailed roles of specific genes in human diseases, both rare and common. KCTD13 is a major driver of mirrored neuroanatomical phenotypes of the 16p11.2 copy number variant. 19, 1639–1645 (2009).

In contrast, the zebrafish genome contains a marked excess of type II DNA transposable elements. DCS blocks are defined as runs of genes in the non-duplicated species that are found on two different chromosomes in the species that underwent a WGD23, although the genes may not be adjacent in the duplicated species24. Double haploid generation zero (G0) founders were sequenced to approximately 40× depth using Illumina GAII technology. This file contains Supplementary Text, Supplementary Tables 1-18, and Supplementary Figures 1-25 and A1-25- see Contents list for more details. Zebrafish genome has also been fully sequenced to a very high quality. 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). 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. The systematic application of genetic screens led to the phenotypic characterization of a large collection of mutations1,2. Some of this increased gene number is likely to be a consequence of the TSD. https://doi.org/10.1038/nature12111, Neurobiology of Aging Moreover, the annotated reference genome has enabled the generation of accurate whole-exome enrichment reagents, which are accelerating both positional cloning projects and new genome-wide mutation discovery efforts26,27. At approximately 27 Mb, the otherwise uniform presence of the satellite repeat SAT-2 on the long arm ends abruptly. Such investigations have also contributed notably to our understanding of basic vertebrate biology and vertebrate development. The Zebrafish Genome Project at the Wellcome Trust Sanger Institute was funded by Wellcome Trust grant number 098051. 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. 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. Genome Res. 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.
