Analysis on Genetic Diversity of Reindeer (Rangifer tarandus) in the Greater Khingan Mountains Using Microsatellite Markers.

ABSTRACT: Jian-Cheng Zhai, Wei-Shi Liu, Ya-Jie Yin, Yan-Ling Xia, and He-Ping Li (2017) The only population of reindeer (Rangifer tarandus) in China, herded extensively by the Ewenki people, is the most southern population in the world. Genetic diversity plays a key role in the survival of endangered reindeer. To systematically understand the genetic variability of reindeer in China, 163 individuals from 8 populations were analyzed using 11 microsatellite loci. A total of 85 alleles were detected and the average number of alleles per locus was 7.7. The observed heterozygosity and expected heterozygosity ranged from 0.3736 to 0.5299 and from 0.6491 to 0.7608. Hardy-Weinberg equilibrium analysis indicated that a de ciency of heterozygotes existed in all eight populations. Both the FST and AMOVA analyses showed a low level of genetic di erentiation among populations. UPGMA dendrogram revealed that population SYL formed one cluster, separating from the other populations. Then the GWQ and YSH populations formed another cluster and clustered with the BDX, BLJY, DML, DW and MLYS populations. Increasing the current exchange rate of reindeer among different populations and establishing natural reserve may be the e ective approaches to conserve the fragile reindeer populations in China.

Project description:Reindeer species (Rangifer tarandus, Linnaeus, 1758) includes wild and semi-domesticated ruminants belonging to Capreaolinae subfamily of Cervidae family reared in Eurasia (reindeer subspecies) and North America (caribou subspecies). Herding of reindeer has a great historical, socio-economic and ecological importance, especially to indigenous ethnic minorities. Infectious disease threats may therefore impact not solely the animal population driving it to further extinction and irreversible alterations to the wild environments of northern hemisphere, but also add to cultural changes observed as negative impact of globalization. Introduction of new technologies to control of reindeer migration between dwindling pasture areas and intensification of reindeer husbandry may facilitate the intra- and interspecies transmission of pathogens. The role of the reindeer as a potential BVDV reservoir has been studied, however, the number of publications is rather limited. The observed seroprevalences of the virus varied significantly between different geographical regions with different epidemiological situation. Most frequently limited number of animals studied and the differences in the sensitivities and specificities of the diagnostic test used could have also influenced on the differences between the studies. No pestivirus has been ever detected in free-ranging reindeer, however, a putative pestivirus strain named V60-Krefeld has been isolated from reindeer kept at a German Zoo in the 1990's. The virus was characterized as border disease virus type 2 (BDV-2) closely related to German ovine strains. The cross-neutralization studies of the semi-domesticated reindeer sera from Sweden suggested infection with a strain related to BDV-1 or BDV-2. The available data indicates that reindeer might be infected by a endemic species-specific BDV-like strain. However, the interspecies transmission of BVDV from domestic animals should not be excluded, since the susceptibility of reindeer to BVDV-1 has been confirmed under experimental conditions.
