“…Purification of the PCR products was performed using Exonuclease I (TaKaRa Bio Inc., Dalian, China) and Shrimp Alkaline Phosphatase (TaKaRa Bio Inc., Dalian, China), and they were sequenced with the BigDye TM Terminator version 3.0 Ready Reaction Cycle Sequencing Kit (Thermo Fisher, Waltham, MA) using the 3730xl DNA Analyser (Thermo Fisher Scientific, Waltham, MA) according to the manufacturer’s manual. Following an earlier report, sequencing primers were used [ 3 ]. A combination of forward and reverse-direction sequencing was used to enhance the data's accuracy.…”

Background Even though the Buyei are a recognised ethnic group in southwestern China, there hasn’t been much work done on forensic population genetics, notably using mitochondrial DNA. The sequences and haplogroups of mitochondrial DNA control regions of the Buyei peoples were studied to provide support for the establishment of a reference database for forensic DNA analysis in East Asia. Methods and results The mitochondrial DNA control region sequences of 200 Buyei individuals in Guizhou were investigated. The haplotype frequencies and haplogroup distribution of the Buyei nationality in Guizhou were calculated. At the same time, the paired Fst values of the study population and other populations around the world were computed, to explore their genetic polymorphism and population relationship. A total of 179 haplotypes were detected in the Buyei population, with frequencies of 0.005–0.015. All haplotypes were assigned to 89 different haplogroups. The haplotype diversity and random matching probability were 0.999283 and 0.0063, respectively. The paired Fst genetic distances and correlation p-values among the 54 populations revealed that the Guizhou Buyei was most closely related to the Henan Han and the Guizhou Miao, and closer to the Hazara population in Pakistan and the Chiang Mai population. Conclusions The study of mitochondrial DNA based on the maternal genetic structure of the Buyei nationality in Guizhou will benefit the establishment of an East Asian forensic DNA reference database and provide a reference for anthropological research in the future.

“…In the past, the genetic studies on the Tai-Kadai population were predominantly based on autosomal, X, Y STRs, and Indels, mainly to assess the effectiveness of forensic identification of STR and Indel markers (Yang et al, 2013;Ji et al, 2017;Chen et al, 2018;Guo et al, 2019;He et al, 2019). Up to now, the published literature has almost only carried out a small amount of analysis on the CR (Le et al, 2019;Feng et al, 2021). The inefficiency of mtDNA markers (HVR/CR) and unrepresentative sampling might hinder the analysis of the genetic structure of the Guizhou Tai-Kadai population.…”

As a single matrilineal gene, human mitochondrial DNA plays a very important role in the study of population genetics. The whole mitogenome sequences of 287 individuals of the Tai-Kadai-speaking population in Guizhou were obtained. It was discovered that there were 82, 104, and 94 haplotypes in 83 Bouyei individuals, 107 Dong individuals, and 97 Sui individuals, respectively; and the haplotype diversity in Bouyei, Dong, and Sui groups was 1.000 ± 0.02, 0.9993 ± 0.0015, and 0.999 ± 0.002, respectively. The result of neutrality tests of the Tai-Kadai-speaking population in Guizhou showed significant negative values, and the analysis of mismatch distribution showed an obvious unimodal distribution. The results implied that Guizhou Tai-Kadai-speaking populations had high genetic diversities and may have experienced recent population expansion. In addition, the primary haplogroups of studied populations were M*, F, B, D, and R*, implying that they may origin from Southern China. The matrilineal genetic structure of the Tai-Kadai-speaking populations in Guizhou was analyzed by merging the mitogenome data of 79 worldwide populations as reference data. The results showed that there were close relationships between studied populations and other Tai-Kadai as well as some Austronesian populations in East and Southeast Asia. Overall, the mitogenome data generated in this study will provide important data for the study of genetic structure of Tai-Kadai speaking populations.
