Abstract

Gotland sheep, a breed native to Gotland, Sweden (an island in the Baltic Sea), split from the Gute sheep breed approximately 100 years ago, and since, has probably been crossed with other breeds. This breed has recently gained popularity, due to its pelt quality. This study estimates the shared ancestors and identifies recent selection signatures in Gotland sheep using 600 K single nucleotide polymorphism (SNP) genotype data. Admixture analysis shows that the Gotland sheep is a distinct breed, but also has shared ancestral genomic components with Gute (~50%), Karakul (~30%), Romanov (~20%), and Fjällnäs (~10%) sheep breeds. Two complementary methods were applied to detect selection signatures: A Bayesian population differentiation FST and an integrated haplotype homozygosity score (iHS). Our results find that seven significant SNPs (q-value < 0.05) using the FST analysis and 55 significant SNPs (p-value < 0.0001) using the iHS analysis. Of the candidate genes that contain significant markers, or are in proximity to them, we identify several belongings to the keratin genes, RXFP2, ADCY1, ENOX1, USF2, COX7A1, ARHGAP28, CRYBB2, CAPNS1, FMO3, and GREB1. These genes are involved in wool quality, polled and horned phenotypes, fertility, twining rate, meat quality, and growth traits. In summary, our results provide shared founders of Gotland sheep and insight into genomic regions maintained under selection after the breed was formed. These results contribute to the detection of candidate genes and QTLs underlying economic traits in sheep.

Abstract

How animals, particularly livestock, adapt to various climates and environments over short evolutionary time is of fundamental biological interest. Further, understanding the genetic mechanisms of adaptation in indigenous livestock populations is important for designing appropriate breeding programs to cope with the impacts of changing climate. Here we conducted a comprehensive genomic analysis of diversity, interspecies introgression and climate-mediated selective signatures in a global sample of sheep and their wild relatives. By examining 600k and 50k genome-wide SNP data from 3447 samples representing 111 domestic sheep populations and 403 samples from all their seven wild relatives (argali, Asiatic mouflon, European mouflon, urial, snow sheep, bighorn and thinhorn sheep), coupled with 88 whole-genome sequences, we detected clear signals of common introgression from wild relatives into sympatric domestic populations, thereby increasing their genomic diversities. The introgressions provided beneficial genetic variants in native populations, which were significantly associated with local climatic adaptation. We observed common introgression signals of alleles in olfactory-related genes (e.g., ADCY3 and TRPV1) and the PADI gene family including in particular PADI2, which is associated with antibacterial innate immunity. Further analyses of whole-genome sequences showed that the introgressed alleles in a specific region of PADI2 (chr2: 248302667-248306614) correlate with resistance to pneumonia. We conclude that wild introgression enhanced climatic adaptation and resistance to pneumonia in sheep. This has enabled them to adapt to varying climatic and environmental conditions after domestication.

Abstract

Simple Summary: The search for genomic regions of putative selective signaling is instrumental in obtaining information about selection history in various species and populations. Domestic animals are subject to long-term artificial selection that leaves certain footprints in their genomes one can explore using genome-wide SNP screen. We examined here genomes of two contrasting chicken breeds, the native egg-type Russian White and meat-type White Cornish. Using three statistics, we identified genomic regions under putative selection, both breed-specific and shared between two breeds, that harbor key candidate genes for economically important traits. Our findings will be useful in further understanding selection history and genomic diversity in domestic chickens that would be pivotal in their productive breeding. Abstract: Comparison of genomic footprints in chicken breeds with different selection history is a powerful tool in elucidating genomic regions that have been targeted by recent and more ancient selection. In the present work, we aimed at examining and comparing the trajectories of artificial selection in the genomes of the native egg-type Russian White (RW) and meat-type White Cornish (WC) breeds. Combining three different statistics (top 0.1% SNP by FST value at pairwise breed comparison, hapFLK analysis, and identification of ROH island shared by more than 50% of individuals), we detected 45 genomic regions under putative selection including 11 selective sweep regions, which were detected by at least two different methods. Four of such regions were breed-specific for each of RW breed (on GGA1, GGA5, GGA8, and GGA9) and WC breed (on GGA1, GGA5, GGA8, and GGA28), while three remaining regions on GGA2 (two sweeps) and GGA3 were common for both breeds. Most of identified genomic regions overlapped with known QTLs and/or candidate genes including those for body temperatures, egg productivity, and feed intake in RW chickens and those for growth, meat and carcas

Abstract

Sheep farming has been an important sector of the UK’s economy and rural life for many centuries. It is the favored source of wool, meat and milk products. In the era of exponential progress in genomic technologies, we can now address the questions of what is special about UK sheep breed genotypes and how they differ genetically form one another and from other countries. We can reflect how their natural history has been determined at the level of their genetic code and what traces have been left in their genomes because of selection for phenotypic traits. These include adaptability to certain environmental conditions and management, as well as resistance to disease. Application of these advancements in genetics and genomics to study sheep breeds of British domestic selection has begun and will continue in order to facilitate conservation solutions and production improvement.

Abstract

Cattle breeds used in industrial production tend to have a larger size compared to the local cattle, as the increased dairy and beef productivity is closely related to the stature. The aim of our work was to identify single nucleotide polymorphisms (SNPs), which are significantly associated with stature in diverse cattle breeds. Thirteen local and transboundary cattle breeds (n = 670) subjected to our study were divided in two groups according to the stature. The high-stature group included Angus, Ayrshire, Black-and-White, Holstein, Kholmogor, Yaroslavl, Tagil and Istoben breeds. The low-stature group comprised of Jersey, Kalmyk, Kyrgyz, Mongolian and Yakut cattle. The average height at withers was 136.3 ± 1.6 and 121.6 ± 2.8 cm in the high- and low-stature groups, respectively. The samples of 11 breeds were genotyped using high-density DNA arrays (Illumina Inc., USA). The genotypes of two remaining breeds were downloaded from the publicly available WIDDE database. Genome-wide association studies revealed four SNPs, which were strongly associated with the stature, including three SNPs at 77.3–77.8 cM on BTA4 (map53144-ss46525999, p < 7.747 × 10−101; BovineHD0400021479, p < 1.173 × 10−91; ARS-BFGL-NGS-116590, p < 7.665 × 10−105) and one SNPs at 25.2 cM on BTA14 (BovineHD1400007259, p < 1.324 × 10−109). Functional annotation showed the localization within identified regions of genes, which are responsible for growth, exterior characteristics, protein and lipid metabolism, and feed intake. Identified SNPs can be considered as useful DNA markers for marker-assistant cattle breeding aimed at increased stature. The study was funded by the Russian Ministry of Science and Higher Education No. 0445-2019-0024. [ABSTRACT FROM AUTHOR]

Abstract

Cheap pasture fodder and a long grazing season are favorable for cattle breeding in the Dagestan Republic of Russia. However, specific natural and geographical conditions, including mountain terrain, hypoxia, and high humidity slow down the intensification of cattle breeding in this region. Thus, the maintenance of genetic diversity of local cattle breeds, which fits well into specific environments, is of special importance for mountain ethnic communities. Dagestan Mountain cattle have valuable biological traits, including strong hooves, stamina, and adaptability to extreme mountain conditions. This sample included 32 individuals of Dagestan Mountain cattle collected from private owners in the mountain villages of Dagestan during a scientific expedition. We observed a high level of genetic diversity in Dagestan Mountain cattle, as revealed by calculations of the mean number of alleles per locus (6.82 compared to 4.79–5.82 in other breeds) and observed heterozygosity indices (Ho = 0.73, which was higher compared to the other breeds (Ho = 0.69) excluding Simmentals and Brown Swiss (Ho = 0.74). Based on STRUCTURE results, the individuals with a low level of admixture with other breeds were found within Dagestan Mountain cattle, which can be considered as candidates for using conservation programs in germplasms.
