Adopting the REMOVE_DUPLICATES=true option in the MarkDuplicates command-line tool of Picard (http://picard.sourceforge.net), potential PCR duplicates were excluded. Distribution plots of XP-EHH raw score. (B) gene regions. 2011;42(6):6216. We also looked for genes related to immune system among genes predicted to be under positive selection in JBP as they exhibit abilities of strong disease tolerance [1]. We then used SAMtools [11] to construct index files for reference and bam files. This statistic is particularly robust to ascertainment bias and population demography. The layers of fat on the cut of meat melt almost instantly when they hit the grill, while the actual meat itself remains firm and soaks up the juicy flavors of the fat and slowly but surely evolves into a piece of pork with a thin crispy layer on the outside with an amazing hidden flavor that is sure to delight you on the inside. Figure S2. Fujii J, Otsu K, Zorzato F, de Leon S, Khanna VK, Weiler JE, et al. GOE Process Timeline Whole-blood samples (10mL) were collected from 8 JBP and 6 KP according to the guidelines for the Care and Use of Laboratory Animals of the Institutional Ethical Committee of Jeju National University. Many candidate genes putatively under positive selection were identified, some of which could be crucial for understanding their unique characteristics. SC, KC, HK and YCR conceived and designed the analysis. Genomic analyses identify distinct patterns of selection in domesticated pigs and Tibetan wild boars.

The local black pigs served as ample sources of protein for the ancient residents of Jeju. Haploview representation of pairwise linkage disequilibria at the CACNA1I and ZBTB24 gene locus in JBP (above) and KP (below) populations. JBP is known for higher marbling score than Western breeds [6] and desirable characteristics such as tenderness, juiciness, redness and brightness [2], besides its strong disease tolerance [1]. 1966;14(3):2017. Figure S6. QTL analysis of white blood cell, platelet and red blood cellrelated traits in an F2 intercross between Landrace and Korean native pigs. The growth of the pork industry has had a considerable effect on Jejus economy, both directly and indirectly.

Furthermore, as the pig is an exceptional biomedical model related to energy metabolism and obesity in humans, analyzing the genetic basis of native pig breeds may be extended to characterize the effect of putative candidate genes for human [49]. 2007;81(5):1084. In our study, the test detected a total of 212 JBP putatively advantageous genes (Table1 and Additional file 2: Table S3). 2013;45(12):14318.

Haplotype homozygosity was estimated between the JBP and KP populations using the cross population extended haplotype homozygosity (XP-EHH) algorithm. Linkage disequilibrium decay and haplotype block structure in the pig. We are building this directory for all animal lovers and pet owners, it is a community project out of BC, Canada aiming to cover all provinces and branch out to cover pet products and services worldwide! After all, this is no ordinary pig that is being served. In addition, analysis using Tajimas D test also showed significant departure from neutrality and indicated the selective maintenance of alleles within the JBP population compared to KP.

The name black pork refers to the color of the animals hair, not the meat itself. Manage cookies/Do not sell my data we use in the preference centre. However, the biological basis for these characteristics of JBP has not been clearly demonstrated. The Jeju Black Pig (heuk-doe-ji) is a breed of domestic pig found on the Korean island of Jeju-do. Contact Us. Heredity. The total revenue of the pork industry grew from KRW 81.3 billion in 1996 to more than KRW 400 billion in 2010. The breed is a combination of three breeds: Danish Landrace pigs, famous for their chewy texture; Yorkshire pigs, characterized by their large size and superb breeding capabilities; and Durok pigs, famous for their rich taste. The haplotypes that are more frequent and longer than expected arise due to the random processes considered to be positively selected [14,15]. I have had meaningful relationships with various animals since I was a toddler and after losing one horse to severe colic and another to cancer. The network showed the prominent gene ontology term plasma membrane long-chain fatty acid transport as enriched, which may have contributed to the change in fatty acid composition and to the unique features of meat quality in JBP (Figure2). GEPIK Process Timeline Yang S, Li X, Li K, Fan B, Tang Z. Park B, Kim N, Lee C, Hwang I. Article Figure S1. An average read depth of 14.26 (9.89~16.98) was achieved, and on average across all samples, the reads covered 98.60% of the genome (Additional file 1: Table S1). To further examine the putatively advantageous genes, we analyzed extreme patterns of haplotype differentiation by performing haplotype analyses (Additional file 1: Figure S4). Relying on the arguments such as RealignerTargetCreator and IndelRealigner arguments, genome analysis toolkit 1.4 (GATK) [12] was used to perform local realignment of reads to correct misalignments due to the presence of insertions/deletions. Dont be fooled by the name. Furthermore, the islands environment is conducive to supply high-quality pork, thereby contributing to the growth of pork restaurant businesses in Jeju. PubMed Am J Hypertens. Positively selected genes were functionally explored and visualized by gene ontology using the ClueGo plugin of Cytoscape [26,27]. Nature. The proportion of SNPs with MAF<0.10 was plotted within multiple 100-kb sliding windows along 1-Mb regions centered on each major candidate gene for each population. 2005;83(10):225563. Since its construction of a 30,000 m2 breeding pig range in 1997, the LPA has been distributing high-quality breeding pigs to pig ranches in Jeju, encouraging them to produce higher quality pork. The vertical dashed bar represents the candidate gene region of each candidate. EPIK Final Documents SNP pairs at a distance of 0.5Mb had an average r2 of 0.26 for JBP and 0.32 for KP, both of which are closer to that for Chinese breeds than for European breeds, as the European pigs showed a higher level of LD [31]. Poult Sci. Korean native pigs show a slower growth rate and lighter carcass weight [2]. Pickrell JK, Coop G, Novembre J, Kudaravalli S, Li JZ, Absher D, et al. The redness of the meat is believed to contribute to a far more complex taste which is often described as having a solid and almost steak like quality to it. Meat Sci. It's not just about appearance. Google Scholar. We investigated the genetic structure using a Bayesian approach to infer population structure between two breeds on a random subset of 159,660 SNPs [23].

Expression of fat deposition and fat removal genes is associated with intramuscular fat content in longissimus dorsi muscle of Korean cattle steers. There was a significant overrepresentation of genes related to positive regulation of immune response from XP-CLR scan (GO:0050778, P=0.036). Google Scholar. Next, the test focuses on the chromosomes in each population to calculate EHH at all SNPs between the core SNP and X; integrates it within these bounds (results are called IA and IB, respectively); finally defines an XP-EHH log-ratio as ln(IA/IB) [15]. Fatty acids are involved in various technological aspects of meat quality. By using this website, you agree to our To further analyze the Jeju black pig genome, we performed whole-genome re-sequencing (average read depth of 14) of 8 Jeju black pig and 6 Korean pigs (which live on the Korean peninsula) to compare and identify putative signatures of positive selection in Jeju black pig, the true and pure Korean native black pigs. Eating out in Korea is a wonderful experience that offers patrons many different delicious foods with a wide range of smells, tastes, and temperatures. As of 2018, a total of 534,113 pigs were being raised in Jeju.
