“…The overall and average N a were very high, reflecting relatively high genetic variability in these donkey breeds. Among Chinese donkeys, the H e ranged from 0.6315 (Guanzhong) to 0.6999 (Jiami), which showed a comparable level to the previous values reported in Spanish (Arangurenméndez et al, 2001) and Croatian coast donkeys (Ivankovic et al, 2015), and was more diversified than Poitou (Bellone et al, 2002), Italian (Colli et al, 2013;Matassino et al, 2014) and American donkeys (Jordana et al, 2016). There was a wide range of values concerning NPA among Chinese donkey breeds.…”

Donkeys are one important livestock in China because of their nourishment and medical values. To investigate the genetic diversity and phylogenetic relationships of Chinese donkey breeds, a panel of 25 fluorescently labeled microsatellite markers was applied to genotype 504 animals from 12 Chinese donkey breeds. A total of 226 alleles were detected, and the expected heterozygosity ranged from 0.6315 (Guanzhong) to 0.6999 (Jiami). The mean value of the polymorphism information content, observed number of alleles, and expected number of alleles for all the tested Chinese donkeys were 0.6600, 6.890, and 3.700, respectively, suggesting that Chinese indigenous donkeys have relatively abundant genetic diversity. Although there were abundant genetic variations found, the genetic differentiation between the Chinese donkey breeds was relatively low, which displayed only 5.99 % of the total genetic variance among different breeds. The principal coordinates analysis clearly splits 12 donkey breeds into two major groups. The first group included Xiji, Xinjiang, Liangzhou, Kulun, and Guanzhong donkey breeds. In the other group, Gunsha, Dezhou, Biyang, Taihang, Jiami, Qingyang, and Qinghai donkeys were clustered together. This grouping pattern was further supported by structure analysis and neighbor-joining tree analysis. Furthermore, genetic relationships between different donkey breeds identified in this study were corresponded to their geographic distribution and breeding history. Our results provide comprehensive and precise baseline information for further research on preservation and utilization of Chinese domestic donkeys.

“…Despite its uniquely maternal origin, nowadays, mtDNA nucleotide sequences are a recognized tool for resolving phylogenetic relationships at different evolutionary level, because of its special properties such as: more copies than nuclear DNA, well-known gene structure, lack of introns, high-mutation rate, absence of recombination events (Xu et al 1996). As such previous studies on donkey mitochondrial DNA D-loop (control region) sequences well depicted the genetic relationships and origin of worldwide modern donkey breeds (Oakenfull et al 2000;Ivankovic et al 2002;Aranguren-Mendez et al 2004;Beja-Pereira et al 2004;Lopez et al 2005;Chen et al 2006;Lei et al 2007;Han et al 2014;Kefena et al 2014;P erez-Pardal et al 2014;Cinar Kul et al 2016).…”

Donkeys have played an important role in agricultural land practices and in human historical periods of recent past and, still today, are used as a working power in several world areas. The objective of this study was to identify genetic variability in six Italian donkey breeds using mtDNA D-loop. Fifteen haplotypes, grouped in three haplogroups, were identified. The genetic indices were informative and showed a high population genetic variability. The results of AMOVA analyses based on geographic structuring of Italian populations highlighted that the majority of the observed variance is due to differences among samples within breeds. Comparison among Italian haplotypes and mtDNA D-loop sequences belonging to European domestic and Ethiopian donkeys and wild asses, clearly define two clades referred to Nubian lineage. The results can be useful to complement safeguard planes for donkey breeds that are considered to extinction endangered.

“…On the other hand, the origin of the species and evolutionary relationship between donkey breeds were analyzed using the mitochondrial DNA markers (Ivankovic et al 2002;Lopez Lopez et al 2005;Chen et al 2006;Zhang et al 2010;Han et al 2014;Perez-Pardal et al 2014), and these results hinted that the modern donkey (including Chinese donkey) has an African maternal origin. In this study, the genetic diversity and structure of five Chinese donkey breeds were assessed using 15 microsatellite markers in order to provide important implications for further conservation and utilization of Chinese donkeys.…”

China had the largest population of raising donkeys in the world, however the number of Chinese indigenous donkey decreased dramatically due to the increase of agriculture mechanization in the last century. The species has still been important in China because of its edible and medical value, therefore the survey on its genetic diversity in China is necessary for its conservation and utilization. In this study, 15 microsatellite markers were used to evaluate genetic diversity and population structure of five Chinese indigenous donkey breeds. The mean values of expected heterozygosity, allelic richness, and total number of alleles for all the tested Chinese donkeys were 0.70, 6.04, and 6.28 respectively, suggesting that the genetic diversity of Chinese indigenous donkeys is rich. The Bayesian analysis and principal component analysis plot yielded the same clustering result, which revealed that Guanzhong donkey was the most differentiated breed in all detected samples, and Jinnan (JN) and Guangling (GL) were genetically closed together. Additionally, our results indicated that the heterozygote deficit was severe in two Chinese indigenous donkey breeds (GL and JN), and it warned us that animal conservation activities on this species should be considered carefully in near future.
