“…Yaks in Qinghai were also close to the wild yak distribution range, suggesting that Qinghai was likely the site of initial yak domestication [ 30 ]. All yaks were divided into three haplogroups; two of these haplogroups (A and B) showed a star-shaped distribution of mitotypes, which was typical of domestic species and consistent with population expansion [ 34 ]. The central mitotypes of A and B were widely distributed and had a high frequency.…”

Background and aim Mitochondrial genome has aseries of characteristics such as simple structure, no recombination, maternalinheritance, stable structure, fast evolution rate, and high copy number. Moreover, it is easy to be sequenced,contains high-resolution phylogenetic information, and exists in a wide rangeof taxa. Therefore, it is widely used in the study of biological phylogeny. Atpresent, phylogenetic studies focus mainly on D-loop region, cytochrome b gene,and protein-coding sequence. Phylogenetic studies using the mitochondrialcomplete sequence are rarely reported in yak. Therefore, the present studyaimed to construct phylogenetic tree using yak mitochondrial complete sequenceand compare the subsequent results with previous findings obtained usingpartial sequences. Results Complete mitochondrial sequences of five yakpopulations from Qinghai and Xinjiang were obtained. The mitotype diversity ofthe five populations was Xueduo yak (0.992 ± 0.015), Pamir yak (0.990 ± 0.014),Yushu yak (0.963 ± 0.033), Qilian yak (0.948 ± 0.036), and Huanhu yak (0.905 ±0.048), which showed a higher mitotype diversity compared with other breeds fromthe previous reports, including Jiulong yak, Maiwa yak, Zhongdian yak, andTianzhu yak. A total of 78 mitotypes were obtained from 111 individuals. Amongthese, Yushu yak, Huanhu yak, Xueduo yak, and Qilian yak all shared mitotypes,but the Pamir yak did not share mitotypes with these four populations.Phylogenetic analysis showed that yak populations were separable into threedistinct branches. The analysis identified a new phylogenetic branch containingboth wild and domestic yaks. The 155 mitotypes found in 206 individuals weredivided into 3 haplogroups by mitotype clustering. Thehaplogroup was not associated with the geographical distribution of yaks. Theyaks in the same population or the same ecological environment were distributedin different haplogroups. Among the threehaplogroups, haplogroup A and haplogroup B showed a star-shaped distribution ofmitotypes. The central mitotypes were widely distributed and had a highfrequency. Conclusions Thegenetic diversity of yaks in Qinghai was high. Both domestic and wild yaks clusteredinto three branches.

“…The swamp buffalo was most likely domesticated near the border between China and Indochina at ∼3,000-7,000 years BP, spreading across Southeast Asia. Swamp buffaloes have strong phenotypic uniformity, but molecular studies show a higher diversity of maternal and paternal lineages, strong genetic differentiation affected by geography, and a lack of gene flow (27,28). One large study with 46 buffalo populations in seven Asian countries revealed an abundant genetic diversity and clear phylogeographic structure in swamp buffalo populations (29).…”

“…Other breeds include the Fuzhong and Xilin breeds from Guanxi province, Enshi breed from Hubei, Dongliu breed from Anhui province, and the Shanghai breed. Swamp breeds in China are mainly used for draft purposes as they are very efficient in the marshlands, particularly in rice fields, and have limited milk production capacity (10,28).…”

The domestic buffalo (Bubalus bubalis), also known as water buffalo or Asian buffalo to prevent confusion with the American bison (Bison bison), wrongly named buffalo in North America, comprises two subspecies: the river buffalo (B. bubalis bubalis) and the swamp buffalo (B. bubalis kerebau). The swamp buffalo has a consistent phenotype and is considered as one type, even if many breeds are recognized within it; conversely, the river buffalo subspecies has many breeds. We found limited information available regarding the worldwide distribution of buffaloes. The best estimate is that 208,098,759 buffalo head are distributed in 77 countries in five continents. In this review, we presented the basic aspects of the water buffalo and unraveled the buffalo path followed from the origin of the species to its current global distribution. We reviewed several data sources to provide a better estimate of the world buffalo count and distribution.

Background and aim: Mitochondrial genome has the characteristics of simple structure, no recombination, maternal inheritance, high conservation, fast evolution, and high copy number. It is easy to sequence, contains high resolution phylogenetic information, and exists in a wide range of taxa. Theref ore, it is widely used in the study of biological phylogeny. At present, phylogenetic studies focus mainly on D loop region, cytochrome b gene, and protein coding sequence; phylogenetic studies using the mitochondrial complete sequence are rare. Therefore, this study aimed to conduct phylogenetic experiments using the mitochondrial complete sequence and compare the results with previous findings obtained using partial sequences. Results: Complete mitochondrial sequences of five yak populations from Qinghai and Xinjiang were obtained. The haplotype diversity of the five populations were Xueduo yak (0.992 ± 0.015), Pamir yak (0.990 ± 0.014), Yushu yak (0.963 ± 0.033), Qilian yak (0.948 ± 0.036), and Huanhu yak (0.905 ± 0.048), which showed a higher haplotype diversity compared with other breeds. A total of 78 haplotypes were obtained from 111 individuals. Among these, Yushu yak, Huanhu yak, Xueduo yak, and Qilian yak all shared haplotypes, but the Pamir yak did not share haplotypes with these four populations. Phylogenetic analysis showed that yak populations were separable into three distinct branches. The analysis identified a new phylogenetic branch with both wild and domestic yaks being represented in the new branch. The 155 haplotypes were divided into 6 haplotype groups by haplotype clustering. The haplotype group had nothing to do with the morphological group of yaks, and yaks from the same population or the same ecological group were distributed in different haplotype groups. The four haplotype groups A, B, C, and D, showed a star-shaped distribution of haplotypes. The central haplotypes were widely distributed and had a high frequency Conclusions: T he genetic diversity of yaks in Qinghai was high. Both domestic and wild yaks exhibited three different mat ernal origins. Three different maternal origins existed in ancient wild yaks before domestication, with haplogroup A being the primary haplogroup associated with yak domestication.
