T5D variants, discovered based on approximately 1380× coverage across individuals (5× for 276 individuals), followed an allele frequency spectrum more similar to known human variants (Figs. The CRISPR/Cas9 methodology works in mice, too, but it is more costly and takes far longer. The zebrafish genome reference assembly: useful URLs. The zebrafish (Danio rerio) has long been appreciated as a unique model system for vertebrate genetics and developmental biology.The zebrafish genome is about half the size of most mammalian genomes [] containing some 4.6 pg of DNA [] distributed across 25 pairs of chromosomes (2n = 50) [].Initial comparisons of zebrafish and mammalian gene maps have revealed extensive … These advantages have led to an upward trend in high-throughput zebrafish chemical screens, especially toward screens of many chemicals using large quantities of fish (Usenko et al. This was performed with the intention to more closely approximate variants that would have been called in T5D, had a pooled approach been employed instead of individual sequencing. The zebrafish (Danio rerio) has emerged in recent years as a powerful vertebrate model to study neuronal circuit development and function, thanks to its relatively small size, rapid external development and translucency.These features allow the easy application of in vivo microscopy analysis and optical perturbation of neuronal function. Carbon N Y 45:1891–1898. Zebrafish variant comparisons after sequencing and masking a pooled subsample. Commonly used to understand gene function. Each of these studies sequenced a pool of zebrafish between 3× and 16× coverage and aligned reads as one sample to the Zv9 reference genome for each line. While this diversity is attractive for translational applications in human and ecological health, it raises critical questions on how interindividual genetic variation might contribute to chemical exposure or disease susceptibility differences. 2009). 2008; Unckless et al. PLoS Biol 6:e216. T5D was found to have more variants compared to results from studies using pooled sequencing and smaller sample sizes (Fig. 1995; Irie and Kuratani 2011). The zebrafish ( Danio rerio ) has become a popular vertebrate model organism to study organ formation and function due to its optical clarity and rapid embryonic development. We find strong evidence for a regulatory role of these interactions, consistent with previous studies that concentrated on highly conserved sequences in vertebrates and involved in genomic regulatory blocks (GRBs) (64). The indel file was further filtered to remove known repeats in the GRCz10 reference build. Toxicological and pharmacological researchers have seized upon the many benefits of zebrafish, including the short generation time, well-characterized development, and early maturation as clear embryos. After applying the filtering cutoffs, 20,385,817 SNPs and 6,304,066 indels remained. https://doi.org/10.1007/s00335-007-9045-1, Sakharkar MK, Perumal BS, Sakharkar KR, Kangueane P (2005) An analysis on gene architecture in human and mouse genomes.

Pooled sequencing data fundamentally affected the character of genetic variation previously detectable in outbred zebrafish lines, versus the individual-level sequencing data collected for T5D. This low-variability region lies within an area of the genome that has primarily zebrafish-specific genes not homologous to other species (Howe et al. volume 29, pages90–100(2018)Cite this article. 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. Genome Biol Evol 3:1187–1196. The resulting VCF files were merged and used, in conjunction with the GRCz10 genome, as input for the GATK FastaAlternateReferenceMaker tool. Additionally, the CVF files had masked variants in non-complex regions of the genome. Zebrafish is a model organism widely used for the understanding of gene function, including the fundamental basis of human disease, enabled by the presence in its genome of a high number of orthologs to human genes. Nat Genet 36:1133–1137. This database of population genomic information can inform future research and can be expanded in later phases and through other projects. This leverages data across samples to assign genotypes for individuals with low coverage at certain bases using a Bayesian likelihood model for genotyping. This is more than have been identified in individual human genomes. There is evidence that chromosome 4 is involved in sex determination in natural zebrafish populations (Wilson et al. (2009)). In Chinese individuals, an average of 3.5 M SNPs and 0.63 M indels were identified (Shi et al. In the haploid state, the zebrafish genome has a size of about 1,412 Gb distributed among 25 chromosomes. 2013).

PubMed  Over more than a decade, tutorials on zebrafish genome wed resources have been held at the European and international zebrafish conferences. In order to create a RIL panel representing the genetic diversity among a more general populace of mice, the collaborative cross (CC) (Chesler et al. For each sample (DNA from an individual zebrafish), reads were aligned to the Genome Reference Consortium GRCz10 (Howe et al. Genome size and statistics on variant counts and distributions were compared across species. By 72 hours their brains are working, and fins and trunk are twitching, and by five days old they are swimming around and they're hunting and they're fully viable organisms.

For environmental health research, this means that healthy laboratory zebrafish strains that are sufficiently outbred, and thus of comparable genetic diversity versus other natural populations, can be a powerful model for environmental exposure studies in humans and other species. All comparisons with these lines were based on the following approximate counts (T5D: 10.3 M SNPs, 2.4 M indels; AB: 4.3 M SNPs, 0.6 M indels; TU: 3.6 M SNPs, 0.4 M indels; TL: 6.2 M SNPs, 0.8 M indels; WIK: 8.5 M SNPs, 1.1 M indels). https://doi.org/10.1002/aja.1002030302, Knecht AL, Truong L, Marvel SW et al (2017) Transgenerational inheritance of neurobehavioral and physiological deficits from developmental exposure to benzo[a]pyrene in zebrafish. After the simulated analysis, median read depth per variant site for T5D was 14 (within the range of 8–16 mentioned previously for the other 4 lines). The comparator lines displayed an abundance of fixed mutations versus the reference genome that were not observed in T5D. The zebrafish is a model organism used to study the development of vertebrates. They have a lot of advantages that are attractive to scientists, one of them being that they are in fact quite cheap to buy, which is always a consideration. For all lines, frequencies were determined based on the proportion of reads with non-reference base calls since no individual genotypes can be determined from pooled sequence alignment. 3). PubMed  Murine retroviral vectors carrying an enhancer detection cassette were used to generate 95 transgenic lines of fish in which reporter expression is observed in distinct patterns during embryonic development. To date, the total number of discovered variants in the zebrafish genome is less than half the number found in human or mouse genomes; consequently, validation is more sparse. PubMed Central  Its importance has been consolidated by successful large-scale forward genetic screens(commonly referred to as the Tübingen/… Arch Toxicol 90:1459–1470. Nonetheless, isogenic models of any species fail to model the influence of genetic diversity on toxicity responses, a critical factor in human responses to toxicants. Their rapid development allows for high-throughput studies that can expand scientific discovery on several axes related to differential susceptibility. 2013) reference genome with Bowtie 2 (Langmead and Salzberg 2012) using standard settings. Variants located in these non-complex regions of the genome were removed from the final T5D comparison dataset resulting in 10,301,547 SNPs and 2,375,455 indels. In order to assess the similarity of T5D variation to a hybrid population that has previously employed an individual sequencing approach, SNP sites were compared to NHGRI-1 SNP sites. 2012; Patowary et al. In brief, genomic DNA was extracted (Zymo Quick-DNA 96-Kit Cat # D3011) from 276 individual larvae exposed to 0.6 µM Abamectin at 120-h post fertilization. However, little is known about zebrafish α-crystallin promoter function, how it compares to that of mammals, or whether mammalian α-crystallin promoter activity can be assessed using zebrafish embryos. Thus, this model could be used for large-scale studies of chemical bioactivity that include genetic information on response mechanisms during development of exposed individuals (Baer et al. For all other lines, frequencies were determined based on the proportion of reads with non-reference base calls since no individual genotypes can be determined from pooled sequence alignment. 2015). https://doi.org/10.1080/15459624.2015.1060325, Depristo MA, Banks E, Poplin RE et al (2011) A framework for variation discovery and genotyping using next- generation DNA sequencing data.

When employed appropriately, these resources can provide insight on a number of variants that should be more in line with that found in a wild-type (WT) population. Nature 2013; 496 (7446): 498-503. A reference for the T5D population is available through GenBank (https://www.ncbi.nlm.nih.gov/genbank/). To ensure consistency between datasets, we performed the same masking procedure on the AB, TU, TL, and WIK datasets even though masking had been previously performed. 2009; Truong et al. 2013).

Additionally, rare variants (those observed at frequencies of < 0.1) would have been missed at small sample sizes. 2012; Bowen et al. The other main advantage, and this is what makes the developmental biologists in the audience get very excited, is that these guys are essentially clear for the first few days of development, and they develop incredibly fast. Many of these sites may actually be variable in the populations (rather than fixed) yet missed in the sampled subsets. 2015). Use of the zebrafish (Danio rerio) as a model organism has gained momentum in vertebrate genomics (Lieschke and Currie 2007). Nat Methods 9:357–359. 2014). The zebrafish and the mouse are the most commonly studied vertebrate laboratory animals whose genomes have been completely sequenced. d Proportion of indels for discrete alternate allele frequencies. PLoS ONE. Reads with a mapping quality below 20 were not included, and a minimum phred-scaled confidence threshold of 10 was required. 2a, c). Findings from pooled samples of zebrafish support this supposition of diversity yet cannot directly measure allele frequencies for reference versus alternate alleles. https://doi.org/10.1086/519795, Asharani PV, Lianwu Y, Gong Z, Valiyaveettil S (2015) Comparison of the toxicity of silver, gold and platinum nanoparticles in developing zebrafish embryos. We have generated lesions ranging from small indels to full gene deletions. The majority of common variants in the human genome have already been discovered, but rare variants continue to be discovered via deep whole genome sequencing of cohorts of individuals from geographically/ethnically defined populations (Shen et al. Part of Springer Nature. This latter trend is very similar to continued improvements in rare allele discovery in humans (Shen et al. First used in the 1960s in biological research, Zebrafish have proven to be excellent model organisms for developmental and disease studies. The adjustment of the MQ threshold from GATK’s recommendation of 40 to 35 accounted for the difference in quality score reporting between the aligner suggested by GATK (BWA) and Bowtie 2. https://doi.org/10.1093/nar/gkw1116, Irie N, Kuratani S (2011) Comparative transcriptome analysis reveals vertebrate phylotypic period during organogenesis.

As a vertebrate with one of the largest sets of protein-coding genes, consisting of orthologues for over 70% of human genes, they have been adapted as exposure and human disease models (Howe et al. Thus, like human populations, most laboratory zebrafish populations contain an unknown level of genetic diversity (Brown et al. The maximum intron size found in each genome is presented in table 1. 2014; Butler et al. Nat Genet 43:648–655. 3). For T5D, the plurality of the variants discovered were rare. Population genetic diversity in zebrafish lines. And they breed very, very well. Despite the small samples (1–2 individual fish or relatively small, pooled samples) used in studies aiming to characterize genetic diversity, results have shown between 5 and 15 million SNPs segregating in a zebrafish population, with roughly half of the variants showing evidence of population-specificity (Obholzer et al. Zebrafish is a relatively new model organism, new kid on the block, if you will. Genetics 190:1017–1024. Next, 20% of each of their reads were randomly selected to create a simulated pooled sample at an average of 20× coverage. There are many benefits to using zebrafish in developmental studies, including early maturation as clear embryos that are amenable to easily observable morphological endpoints, short generation time, and well-characterized development that is conserved across species during the phylotypic period (Kimmel et al. 2016). 2010) HaplotypeCaller was used to call genotypes on all samples simultaneously (joint genotyping). https://doi.org/10.1007/s11051-009-9740-9, Article  Zebrafish 10:15–20. It came into awareness in the scientific community, at least for geneticists, roughly around 1981 when the late George Streisinger, looking for a new genetic organism to study, picked up a couple of zebrafish at the local pet store and started to do a few experiments with them. https://doi.org/10.1016/j.taap.2017.05.033, Kovács R, Csenki Z, Bakos K et al (2015) Assessment of toxicity and genotoxicity of low doses of 5-fluorouracil in zebrafish (Danio rerio) two-generation study. 2012). 2011). Our observations suggest that interindividual genetic diversity (i.e., natural variation) within laboratory populations may be higher than currently estimated and may have implications for differential susceptibility observed in toxicological studies. Using the Tanguay lab Tropical 5D zebrafish line (T5D), we performed whole genome sequencing on a large group (n = 276) of individual zebrafish embryos. Genetics 206(2):537–556, Stanley KA, Curtis LR, Massey Simonich SL, Tanguay RL (2009) Endosulfan I and endosulfan sulfate disrupts zebrafish embryonic development. Subsampling to simulate a pooled sequencing approach showed that T5D variation is in line with the more variable zebrafish laboratory strains (Fig. 2007; Bai et al. 2016) was also run on the set of T5D variants to determine their predicted effects and consequences. We can delete integral domains or the entire the coding sequence of a gene in zebrafish, depending on gene size. To filter T5D variants accordingly, the repeat masked annotation of Zv9 was downloaded from http://hgdownload.soe.ucsc.edu/goldenPath/danRer7/database/rmsk.txt.gz. The sequencing data are described in detail in (Balik-Meisner et al., submitted). Though more SNPs were found in a T5D sample that included more individuals, the two NHGRI-1 founders carried non-reference alleles at more sites (an average of 12.8 M variant sites per individual compared to 6.9 M in T5D). Though these SNPs are private to all save a handful of people, they are only prevalent in specific subpopulations. The T5D zebrafish are housed at Sinnhuber Aquatic Research Laboratory (SARL) at Oregon State University and maintained in accordance with their Institutional Animal Care and Use Committee protocols. The red box contains the variant effects for the 20.1 M SNPs found in T5D. After the release of Zv9, the project joined the Genome Reference Consortium (GRC) for further improvement and ongoing maintenance. These are not solitary outliers, however, with 1,228 (0.6%) D. reriointrons greater than 50,000 bp in size (here referred to as “large introns” after Shepard et al. 2012). 1a). ↑ Wellcome Trust Sanger Institute, Family ties: Relationship between human and zebrafish genomes. 2014; Asharani et al. 2015).

One reason for the success of zebrafish as a model organism is its amenability to genetic manipulation. Cited [4/12/16]. This can be explained in part by the heavy reliance of the reference genome sequence on TU zebrafish.

Additionally, population genetic information can be used to determine variants (SNPs, copy-number variants, etc.) https://doi.org/10.1155/2008/565631, Howe K, Clark MD, Torroja CF et al (2013) The zebrafish reference genome sequence and its relationship to the human genome. The GRC has now released a new reference assembly, GRCz11. DGE-1252376. The estimate of 20.1 M SNPs segregating in the population (10.3 M in non-repetitive regions of the genome used for zebrafish line comparisons) included non-reference allele frequencies from 0.1 to 99.8%. Estimates in other species have been similar (4.9 SNPs per kb in sheep, 5.5 SNPs per kb in chickens, 10.1 SNPs per kb in fly, and 13.9 SNPs per kb in mouse), though they have been based on combined line/breed data (Ka-Shu Wong et al. However, because ethnic/population-level choice of reference may influence the number of variants called (Cho 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. https://doi.org/10.1016/j.gdata.2014.10.013, Article  The 20.1 M SNPs equate to 13.4 SNPs per 1 kb genomic sequence. https://doi.org/10.1093/bioinformatics/btp352, Lieschke GJ, Currie PD (2007) Animal models of human disease: zebrafish swim into view. We theorize that some subset of the novel SNPs may be shared with other zebrafish lines but have not been identified in other studies due to the limitations of capturing population diversity in pooled sequencing strategies. GRCz11 shows a significant reduction in scaffold numbers and increase in scaffold N50 whilst the overall genome size was not affected. Because of the optical transparency of the embryos, small size at maturity and ease of culture, Zebrafish has become a popular organism to study embryonic development for biologist worldwide. Although they are native to South Asia (Nepal, India, etc), Zebrafish are among the most common aquarium fish. The abundance of sites with non-reference alleles per T5D zebrafish could imply that within a population, zebrafish are more genetically variable than humans. 2015). These results were compared to the other species (human and mouse). https://doi.org/10.1038/nmeth.1923, Li H, Handsaker B, Wysoker A et al (2009) The sequence alignment/map format and SAMtools. A common approach to unravel the gene networks that drive biology is to examine the consequences of manipulating genes. Thus, inclusion of knowledge regarding constitutive genetic diversity will benefit all translational applications of the zebrafish model, from the mechanistic to the ecological to the clinical.
