Abstract
Budorcas taxicolor bedfordi is a rare animal uniquely distributed in the Qinling Mountains (China). Human disturbance and habitat fragmentation have directly affected the survival of B. t. bedfordi. It is urgent to clarify the genetic diversity and genetic structure of the B. t. bedfordi population and implement effective conservation measures. In this study, 20 new polymorphic microsatellite loci were isolated by Illumina sequencing. The genetic diversity and population structure of 124 B. t. bedfordi individuals from three populations (Niubeliang population, Zhouzhi population, and Foping population) were analysed according to these 20 microsatellite loci. Our results indicated that B. t. bedfordi had a low level of genetic variability and that there was inbreeding in the three populations. The population genetic structure analyses showed that the Niubeliang population had a trend of differentiation from other populations. National roads can affect population dispersal, while ecological corridors can promote population gene exchange. None of the three B. t. bedfordi populations experienced bottleneck effects. For conservation management plans, the Zhouzhi population and Foping population should be considered one management unit, and the Niubeliang population should be considered another management unit. We suggest building an ecological corridor to keep the habitat connected and formulating tourism management measures to reduce the influence of human disturbance on B. t. bedfordi.

Abstract
Abstract
The aim of the study was to evaluate the genetic structure of the reconstituted native Carpathian goat breed based on information from microsatellite markers. The study analysed of 14 microsatellite markers recommended by the International Society for Animal Genetics (ISAG) for goats individual identification and parentage testing. Blood samples were taken from 249 Carpathian goats from 14 farms. All microsatellite markers deployed in this analysis showed sufficient polymorphism to assess genetic variation in Carpathian goats and the ISAG-recommended panel for goat individual identification and parentage testing is a highly useful one. The present study showed the status of the genetic structure of the reconstituted population of Carpathian goats. Carpathian goats maintained in Poland were characterized by relatively high genetic diversity (the average of alleles per locus was 9.143), high values of heterozygosity and a low level of inbreeding coefficient. The obtained parameters indicate the correctness of the breeding activities carried out within the framework of the programme for the protection of genetic resources and give guidelines for taking further steps related to the breeding of this valuable native breed.

Abstract
Based on 16 STR-loci, the allele pool and interbreed differentiation of goat breeds of Russian and foreign breeding were investigated in this study. These breeds included Karachai (KRCH-K, n=73, mountain zone; KRCH-Z, n=33, foothill zone), Dagestan Downy (DAGD, n=30), Dagestan Wool (DAGW, n=30), Soviet Wool (SOVW, n=30), Saanen (SAAN, n=34), Murciano-Granadina (MURS, n=37), as well as wild goats, represented by three species of mountain goats (n=52): Siberian Capricorn (Capra sibirica) of Altai (CSIB-S, n=6), Tajikistan (CSIB-T, n=4), Kyrgyzstan (CSIB-K, n=6), and the Himalayas (CSIB-H, n=4); Bezoar goat (Capa aegagrus) of Turkey (CAEG, n=3) and Pakistan (CAEG-S, n=3); West Caucasian tur (Capra caucasica): western Caucasian (Kuban, CCAU-K, n=10), central Caucasian (CCAU-M, n=8), and eastern Caucasian (Dagestan, CCAU-D, n=8). The highest genetic diversity was observed in the North Caucasus breeds, such as Karachai, Dagestan Downy, and Dagestan Wool. The mean numbers of alleles per locus and allelic diversity were 7.385-9.154 and 7.353-7.713, respectively. The genetic proximity of Caucasian breeds was confirmed by cluster analysis, and they formed a common branch with the highest genetic affinity, while the Orenburg and Soviet Wool breeds formed another branch, and the third branch with the least affinity was the dairy breed of foreign selection.The analysis of the phylogenetic tree of domestic and wild species established the formation of three clusters formed by the subspecies of the West Caucasian tur, Siberian ibex, and breeds of domestic goats. At the same time, populations of the Bezoar goats were localized at the root of the last cluster, which confirmed their role as the ancestors of domestic goats.

Abstract
Background The continuous accessibility of local animals for sustainable use is being eroded annually. Thus, a strategic vision for the conservation of biodiversity is of far-reaching emphasis to deal with unprecedented challenges in the local population extension facing in the future. This study aimed to establish and cryopreserve endangered Markhoz goat (Capra hircus) fibroblast cell lines in vitro. Methods and results These primary fibroblast cells were isolated from 58 Iranian Markhoz goats and individually cultured by explant technique in DMEM medium supplemented with 10% FBS and 2 mM L-Glutamine, in the presence of Penicillin (200 U/ml)—Streptomycin (200 mg/ml) during the first passage number. The extracted cell lines were confirmed morphologically as fibroblast cells. The population doubling time for DMEM-cultured cells was 23 ± 0.5 h. Chromosomal analysis indicated a total chromosome number of 2n = 60 with > 95% frequency. The cultured cells were checked for bacteria, fungi, yeast, and mycoplasma contaminations and the results were reported negative. The efficiencies of the fluorescent protein encoded by VSV-G (pMDG) and lentiviral pCSGW vectors reported in a range of 65% value. According to the species identification analysis, the goat cell lines were banked and confirmed without any miss- and cross-contamination. Conclusions The significant issue in this paper can be concluded about the first report of the establishment of endangered Markhoz goat cell banking inside the country. This study demonstrated the successful establishment of a genetically stable fibroblast bank as a valuable genetic resource for the endangered Iranian Markhoz goat breed.

Abstract
Genetic diversity in livestock breeds is required for breeding studies, response to environmental changes and sustainable production. The aim of this study was to evaluate the genetic diversity in Hair goats reared in 9 districts of Antalya province and to determine the populations that have the highest contribution to the total genetic diversity. For this purpose, 180 samples from 9 districts (Korkuteli-KRK, Elmalý-ELM, Kaþ-KAS, Demre-DMR, Manavgat- MNG, Gündoðmuþ-GND, Ýbradý-IBR, Akseki-AKS and Gazipaþa-GZP) of Antalya province were genotyped by 20 microsatellite loci. The mean number of alleles per locus for each population ranged from 8.45 (GND) to 9.25 (MNG), while mean number of effective allele varied between 5.40 (GND) and 6.22 (MNG). The lowest average observed heterozygosity was in the ELM populations (0.71) while the highest Ho value detected in KAS populations (0.78). Mean expected heterozygosity values varied from 0.80 (GND) to 0.84 (DMR, MNG). Mean PIC values ranged from 0.77 (GND, AKS) to 0.80 (DMR, MNG) in populations. Inbreeding coefficients were detected between 0.05 (KAS) and 0.13 (ELM) in district populations. According to two different methods, the highest contribution to the total genetic diversity comes from KAS (-0.244) and AKS populations (0.482). In conclusion, high genetic diversity and low level of inbreeding were determined in Turkish indigenous Hair goats. Hair goats have great potential for breeding studies and for adaptation to the environmental conditions that will possibly change in the future. Especially, genetic variation in KAS and AKS populations should be conserved.

Investigating the Polymorphism of Bone Morphogenetic Protein Receptor-1B ( BMPR1B) Gene in Markhoz Goat Breed. Animals (Basel) 2020; 10:ani10091582. [PMID: 32899883 PMCID: PMC7552263 DOI: 10.3390/ani10091582] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2020] [Revised: 08/25/2020] [Accepted: 09/03/2020] [Indexed: 01/29/2023] Open
Abstract
Reproductive traits in livestock species are genetically controlled by the action of single genes with a major effect, commonly known as fecundity genes. One of the genes involved in controlling prolificacy is BMPR1B (FecB), a dominant autosomal gene located in chromosome 6 responsible for the fecundity and twinning rate in sheep and goat species. Markhoz goat is a valuable Iranian genetic resource endangered by extinction. Increasing the genetic variability and reproductive performances of Markhoz goat could preserve and enhance its economic value. This study was carried out to detect possible polymorphisms in BMPR1B gene in a sample of 100 Markhoz goats from Iran. DNA samples were screened by PCR-RFLP to assess the presence of the previously reported FecB mutation. Finally, the amplicons from seven goats out of the 100 samples were sequenced. The results showed that all the analyzed individuals did not carry the previously reported FecB mutant allele. However, our findings revealed two novel possible mutations in exon 8 of BMPR1B gene (775A > G and 777G > A) that need further investigations.

Molecular Identification of the "Facciuta Della Valnerina" Local Goat Population Reared in the Umbria Region, Italy. Animals (Basel) 2020; 10:E601. [PMID: 32244771 PMCID: PMC7222817 DOI: 10.3390/ani10040601] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2020] [Revised: 03/27/2020] [Accepted: 03/30/2020] [Indexed: 11/17/2022] Open
Abstract
Italy holds important genetic resources of small ruminant breeds. By distinguishing goat breeds at the DNA level, certification of products from specific breeds can be valorized. The aim of this study was to establish the genetic identity of Facciuta della Valnerina, a local goat population of Italy, compared with the cosmopolitan breeds, Saanen and Camosciata delle Alpi, reared in the same geographic area. A total of 116 microsatellite alleles ranging from 4 to 13 were detected at 16 loci in the three goat populations/breeds. A total of 23 private alleles with frequencies lower than 0.3 were detected in the Facciuta della Valnerina population. The mean numbers of alleles were 6.67, 4.58, and 4.92 in Facciuta della Valnerina, Camosciata delle Alpi, and Saanen, respectively. The expected heterozygosity ranged from 0.20 to 0.86. Most loci were highly polymorphic and informative (polymorphic information content ≥0.50). Factorial correspondence analysis and principal components analysis revealed very clear separation between Facciuta della Valnerina and the two reference goat breeds. Reducing the number of markers from 16 to 12 (on the basis of polymorphic information content and the number of alleles) still allowed us to distinguish the local population, indicating that microsatellite markers are capable of discriminating local livestock breeds at a low cost.
