Data from: Applying plant DNA barcodes to identify species of Parnassia (Parnassiaceae)

DNA barcoding is a technique to identity species by using standardized DNA sequences. In the present study, a total of 105 samples, representing 30 Parnassia species were collected to test the effectiveness of four proposed DNA barcodes (rbcL, matK, trnH-psbA and ITS) for species identification. Our results demonstrated that all four candidate DNA markers have a maximum level of primer universality and sequencing success. As single DNA marker, ITS region provided the highest species resolution...
Data from: COI is better than 16S rRNA for DNA barcoding Asiatic salamanders (Amphibia: Caudata: Hynobiidae)
Yun Xia, Hai-Feng Gu, Rui Peng, Qin Chen, Yu-Chi Zheng, Robert W Murphy & Xiao-Mao Zeng
The 5’ region of the mitochondrial DNA (mtDNA) gene cytochrome c oxidase I (COI) is the standard marker for DNA barcoding. However, because COI tends to be highly variable in amphibians, sequencing is often challenging. Consequently, another mtDNA gene, 16S rRNA gene, is often advocated for amphibian barcoding. Herein, we directly compare the usefulness of COI and 16S in discriminating species of hynobiid salamanders using 130 individuals. Species identification and classification of these animals, which...
Data from: A phylogeographic, demographic and historical analysis of the short-tailed pit viper (Gloydius brevicaudus): evidence for early divergence and late expansion during the Pleistocene
Li Ding, Xiao-Ni Gan, Shun-Ping He & Er-Mi Zhao
The impact of quaternary glaciation in eastern China on local fanua and flora has been a topic of considerable interest. We used mitochondrial DNA (mtDNA) sequence data and coalescent simulations to test two general biogeographic hypothesis related to the effects of Pleistocene climatic fluctuations for a widespread ophidian species (Gloydius brevicaudus) in eastern China and Korean Peninsula. The phylogenetic analysis revealed three major lineages, the southeast Coastal, Yangtze and North Lineages. The latter two are...
Data from: Wolbachia infection and dramatic intraspecific mitochondrial DNA divergence in a fig wasp
Jin-Hua Xiao, Ning-Xin Wang, Robert W. Murphy, James M. Cook, Ling-Yi Jia & Da-Wei Huang
Mitochondria and Wolbachia are maternally inherited genomes that exhibit strong linkage disequilibrium in many organisms. We surveyed Wolbachia infections in 187 specimens of the fig wasp species, Ceratosolen solmsi, and found an infection prevalence of 89.3%. DNA Sequencing of 20 individuals each from Wolbachia-infected and uninfected sub-populations revealed extreme mtDNA divergence (up to 9.2% and 15.3% in CO1 and cytochrome b, respectively) between infected and uninfected wasps. Further, mtDNA diversity was significantly reduced within the...
