MS PE The new reference, UU_CFam_GSD_1.0/canFam4 (henceforth called GSD_1.0), was subsequently annotated with both novel and published whole-genome sequencing (WGS), assay for transposase-accessible chromatin (ATAC) and RNA sequencing to enhance gene models and variant annotation. Acland SNPs and indels were called from short reads aligned to the polished assembly (FreeBayes60 v1.1.0). 36, 19031908 (2008). B) Each chromosome is replicated into two chromatids during the S phase of interphase. In total, 1000ng of total RNA was reverse transcribed using the Advantage RT-for-PCR Kit (Takara) and qPCR performed in quadruplet using SYBR Green PCR Master Mix (Thermo Fisher Scientific) and 900nM primers in a QuantStudio 6 Real-Time system (Thermo Fisher Scientific) with standard cycling and dissociation curve analysis. A total of 16 dog chromosomes appear to correspond to only one human . 1c). For example, the code from one gene may lead to proteins that add color to a hair shaft, the code from another gene produces enzymes to digest food, and a third gene will direct the formation of antibodies that fight diseases. . K A Sondka, Z. et al. Importation of canine tissues was approved by Jordbruksverket (6.7.18-14513/17). Study Resources. Cite this article. In the last decade, scientists working at more than 100 laboratories worldwide have made significant progress in painting a detailed picture of the complex relationships between physical traits, behavior and disease in purebred dogs . . Subsequent intersection with protein coding genes showed that 1.4% of these could directly influence gene products, and so provide a source of normal or aberrant phenotypic modifications. RL Both detected SVs using evidence from split and paired reads, and also assembled the sequences of breakpoints to accurately estimate these positions. . Recently, markers linked to canine progressive rod-cone degeneration ( prcd ) have been mapped to a region of dog chromosome 9 showing conserved synteny with human chromosome 17q, the mapped location of retinitis pigmentosa RP17 ( Acland and others 1998 ). N Two housekeeper primer sets (RPS19 and RPS5) were assessed for stability (Normfinder87 R package) and used in combination to calculate relative gene expression88. Clin. The assembly used multiple sequencing technologies. Cluster 2 included largely mastiff-type dogs with big, boxy heads and large, sturdy bodies. Ebbert, M. T. W. et al. CAS Dogs will also be a valuable species lot mapping a number of complex genetic diseases including heart disease, hip dysplasia, narcolepsy, atopy, and behavioral traits. Copy of WORKSHEET3 Virus Structure and Function.pdf. The canine genetic map is in its infancy, although rapid progress is now being made. Humans, for instance, have 46 chromosomes in a typical body cell (somatic cell), while dogs have 78 ^1 1. Each of the 78 chromosomes contains the codes for hundreds of genes. 20, 117 (2019). Chromosomes are located within the nucleus of our cells. Article P A EA 6). Rice Association between polymorphisms in the SOX9 region and canine disorder of sex development (78,XX; SRY-negative) revisited in a multibreed case-control study. The individual dark regions were merged, and the dark fraction for each window was assessed for both ISR and 10x datasets: windows with Fdark>0.9 (90% individuals, in at least 23 ISR dogs or 25 10x dogs) retained as the candidate dark regions. Chromosomal conditions are also thought to be rarer in dogs. The only genetic elements of the region are the long noncoding RNA (lncRNA) AL353753.1 gene with an unknown function and pseudogene FAM71BP1.

AK Fate Chem. Goldstein, A. M. et al. BMC Genomics 13, 324 (2012). The results demonstrate that the domestic dog is an extremely close relative of the gray wolf, with as little as 0.2% variation in mitochondrial DNA sequence between the 2 species. NG Dogs come in countless shapes and sizes and exhibit more diversity than any other land mammal on earth, a fact that makes them especially appealing to geneticists. Genome Res. Annotation with generated and existing long and . Protein Cell 10, 143148 (2019). Nat. The breakpoint region on chromosome 9 has several areas of high homology with the breakpoint region on chromosome 15 that may have served as a substrate for the balanced-reciprocal-translocation event.

Wiegand To drive canine comparative genomics forward, we generated a high-quality canine reference assembly using a combination of Pacific Biosciences (PacBio) long read sequencing, 10x Genomics Chromium Linked Reads (henceforth called 10x) and HiC proximity ligation. Perhaps the largest gain offered by the contiguity of GSD_1.0 is to the accelerating field of low pass genotyping and imputation for trait mapping7. A lower cutoff was applied in low-coverage samples to select a maximum of 60Mb (Supplementary Data3). This miRNA has been implicated in several human diseases, including multiple sclerosis17, gastric cancer18 and breast cancer19, but has yet to be extensively studied in dogs. The vast majority of pedigree dog breeds have been selectively bred over the last 200 years, although the origin of many of the breeds is uncertain. After accounting for CYP1A2 SNP rs852922442-T, no significant relative gene expression difference was observed, leaving the phenotypic consequence of this expansion unresolved (CNV 3 vs >3; Supplementary Table7). All tissue samples were amplified with PBC096 barcoding for 810 cycles with both LongAmp (female samples, 62C annealing; NEB) and PrimeSTAR GXL (both sexes, 64C annealing; Takara Bio), with a 10minutes extension time. EA Mellersh For example, microsatellites derived from the domestic dog were used to analyze hybridization between the Ethiopian wolf (the world's most endangered canid) and the domestic dog. Likewise, 76 variants were found in ADCY2 ISR dark/camouflaged regions (Supplementary Fig. Tumor cells can migrate to other organs and begin to grow there. Gffread70 was used to re-group transcripts into genes, retaining only one transcript per unique CDS region. A novel gene was defined if it (1) had at least 80% of the gene body identified from the filled CanFam3.1 gaps; (2) was not a pseudogene; (3) had not been annotated in the unplaced scaffolds of CanFam3.1; and (4) did not have the duplicated/homologous fragment in another region of the genome. Several resources have been developed to complement the basic genetic linkage mapping of microsatellite markers that has been carried out on the reference families described above. Genetics is an area with exponential growth in recent years, and much of this is due to recent technological advances that have allowed for the entire genome of many species, including dogs, to be deciphered. Recently it was shown that the DSD phenotype presents in a breed-specific manner, and is influenced by the combination of an SNP and CNVs in this region38,40. Genome Biol. Two recent papers have reported extensive genetic linkage studies in the dog ( Lingaas and others 1997 ; Mellersh and others 1997 ). Holmes Long read technology allowed for the further resolution of centromeric repeats, and based on their positions, the orientation of chr 27 and 32 were reversed compared to CanFam3.1. Telomeres protect chromosomes during DNA replication. CAS For most of these, the underlying genetic lesion has not been found. In the absence of a Y chromosome, females develop ovaries (see Chapter 7). Using new and sophisticated approaches, talented bioinformaticians can compare genome sequence from large numbers of individuals to find single mutations.

We proposed that those homologous fragments should be located together with a duplication (DUP2, chr 9: 10.0310.16Mb) within a large duplicated region (DUP1, chr 9: 9.0710.25Mb). Yuzbasiyan-Gurkan Protoc. RH a Size distribution and overlap with exons and promoters for the filled CanFam3.1 gaps. MA Publishers note Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations. Heredity 123, 746758 (2019). b Reads from both original and homologous M1, M2 and M3 fragments were mapped to chr 18 of GSD_1.0. Most genes control more than one function within the dog. Ostrander Each species has its own characteristic number of chromosomes. Chao Wang or Kerstin Lindblad-Toh. The availability of dog chromosome paints also enables reciprocal ZOO-FISH (cross-species) experiments to be undertaken with human chromosome paints and metaphase spreads to define the comparative chromosome organization in the 2 species. Full-length CYP1A2 sits within copies of the green fragment. 10,41154128 (2020). Mhleisen, T. W. et al. It may be that the effect in this region is subtle, and so not detectable with qPCR; however, CYP1A2 is an inducible gene and so the true outcome may only be observed after a drug challenge45. 467, 1928 (2019). . de Anda-Juregui, G., Espinal-Enrquez, J., Drago-Garca, D. & Hernndez-Lemus, E. Nonredundant, highly connected microRNAs control functionality in breast cancer networks. To identify which chromosome harbored the majority of the DEGs, we analyzed the chromosomal location of all DEGs. At the time of this writing, very few of the inherited diseases in dogs have been characterized at the molecular level. Tragically, many dogs with such . Scientists, ever mindful of the fact that undesirable alleles along with good alleles will be passed from parent to offspring, often work for years to understand the true function of a protein in order to improve the health of the dogs they are studying. Linked reads were sequenced from HMW DNA with Chromium libraries (10x Genomics) on an Illumina HiSeq X (2150bp; 269.75Gb of data). In contrast, Mellersh and others (1997 ) mapped 150 microsatellite markers onto large 3-generation cross-bred reference families to generate a framework map, and they identified 30 linkage groups comprising 2 or more markers. RL Camouflaged regions (camouflaged) were defined if the coverage was 10 and the proportion of high mapping quality reads was less than 10%. Chromosome-Specific Single-Locus FISH Probes Allow Anchorage of an 1800-Marker Integrated Radiation-Hybrid/Linkage Map of the Domestic Dog Genome to All Chromosomes. Loss of cadherin related family member 5 (CDHR5) expression in clear cell renal cell carcinoma is a prognostic marker of disease progression. Forty-nine discordant end pairs (red curves; >500kb or not in a forwardreverse direction) were found at the edge of rearranged fragments in CanFam3.1, whereas these were properly mapped in GSD_1.0. Parfitt Long read libraries were prepared with SMRTbell Template Prep Kit 1.0 and 70 SMRT cells were sequenced on the PacBio Sequel system with v2.1 chemistry (Pacific Biosciences; 276.86Gb data). Length of DNA. Larger-scale SVs, >30kb, were identified as regions where paired coverage of genomic loci shared many more barcodes than expected by chance. The black or brown nose correlated perfectly with the absence or presence of the same three TYRP1 variants described above.

Neal Finally, transcripts which had either >2 exons downstream of the stop codon, or a bad BLAST classification (<50% hit) were removed if they belonged to a group with high scoring transcripts (Supplementary Fig. . North Am. Court, M. H. Canine cytochrome P-450 pharmacogenetics. Google Scholar. . By analyzing DNA samples from over 200 dog breeds . Chromosome Meaning and Discovery. Gene predictions and non-dog refSeq alignments were used to identify potentially missed genes that did not overlap with our annotation, yielding an additional 874 protein-coding genes with BLAST evidence. dog chromosome 1 function. Genetic variation occurs when "mistakes" are made in the cell's duplication or repair mechanisms that cause a permanent change in the nucleotide sequence of the gene. The PacBio long reads, HiC, and Illumina 10x data of Mischka are available in SRA under BioProject PRJNA587469. Int. Single strand conformation polymorphism (SSCP 1 ) studies have indicated that the mutation in -cGMP phosphodiesterase is probably not responsible for PRA in other breeds with this disease. Crandall Lingaas and others (1997 ) mapped 94 markers onto 2-generation reference families comprising purebred German shepherds and beagles. Wayne 12, 656664 (2002). 34, 835846 (2004). Google Scholar. X . Q. Mitochondrial DNA sequences have also been used to examine the evolution of the Canidae and the origins of the domestic dog ( Wayne 1993 ). Chromosome 1: Chromosome 1 is one of the largest chromosomes among the 23 pairs of chromosome present in humans. PS G Reads from BARKbase72 (Supplementary Data1) were aligned with BWA mem and peaks called with Genrich (https://github.com/jsh58/Genrich). Durra P These calculations included primer specific efficiencies and used the average Ct from all control samples for initial delta Ct normalisation. P Wong, A. K. et al. Commun. This is double the haploid chromosome number. Refinement of the dog map will facilitate the identification of candidate genes for these complex disorders in human and other species through comparative mapping. Methods 10, 563569 (2013). Marrano Visit the Image . The wolf (including the dingo and domestic dog), coyote, and jackal, all have 78 chromosomes arranged in 39 pairs. While this type of de novo collection is on-going within the canine community, GSD_1.0 is the first genome of reference quality that is further annotated with novel long read RNA sequencing data, allowing for the resolution of transcript complexity through regions with high GC context, or dark regions31. The recessive b variant causes an X-linked genetic disease. Nature 438, 803819 (2005). Kimura, K. et al. Many of the microsatellites derived from the domestic dog are polymorphic in other canids, and indeed they have been used to look at wild canid populations.
