Shanxi population of musk deer: species re-identification and genetic relationships with its sister species based on mitochondrial genomes

We examined variation in and around the region coding for the cytochrome c oxidase I (coxI) and ATPase 6 (atp6) genes in the mitochondrial genomes of four Populus species (P. nigra, P. deltoides, P. maximowiczii, and P. tremuloides) and the natural hybrid P. × canadensis (P. deltoides × P. nigra). Total cellular DNAs of these poplars were digested with 16 restriction endonucleases and probed with maize mtDNA-specific probes (CoxI and Atp6). The only variant observed for Atp6 was interspecific, with P. maximowiczii separated from the other species as revealed by EcoRI digestions. No intraspecific mtDNA variation was observed among individuals of P. nigra, P. maximowiczii, P. × canadensis, or P. tremuloides for the CoxI probe. However, two varieties of P. deltoides were distinct because of a single site change in the KpnI digestions, demonstrating that P. deltoides var. deltoides (eastern cottonwood) and var. occidentalis (plains cottonwood) have distinct mitochondrial genomes in the region of the coxI gene. Populus × canadensis shared the same restriction fragment patterns as its suspected maternal parent P. deltoides. Nucleotide substitutions per base in and around the coxI and atp6 genes among the Populus species and the hybrid ranged from 0.0017 to 0.0077. The interspecific estimates of nucleotide substitution per base suggested that P. tremuloides was furthest removed from P. deltoides and P. × canadensis and least diverged from P. nigra. Populus maximowiczii was placed between these two clusters.Key words: mitochondrial DNA, poplars, phylogenetics, variation, restriction fragment length polymorphisms.

AbstractFive musk deer species (genus Moschus) are distributed in China, and the present estimated numbers in the wild are between 220 000 and 320 000. Population size of musk deer has dropped significantly due to historical over-hunting and loss or degradation of their habitat. Musk deer farming, therefore, has become one of the most appropriate ways to protect and utilize musk deer resources. In China, musk deer farming and extracting musk from the captive musk deer have been reasonably successful since the early 1950s. At present three species of musk deer, namely forest (Moschus Berezovskii), alpine (M. sifanicus) and Siberian (M. moschiferus) musk deer are farmed in China and, of these, the forest musk deer is the main captive population. The present patterns of musk deer farming in China, however, need to be improved and developed into more economic and scientific modes in order to improve the rate of survival and reproduction, and to increase the production of musk.

This study was carried out to provide information on the taxonomic classification and analysis of mitochondrial genomes of Spirometra theileri. One strobila of S. theileri was collected from the intestine of an African leopard (Panthera pardus) in the Maswa Game Reserve, Tanzania. The complete mtDNA sequence of S. theileri was 13,685 bp encoding 36 genes including 12 protein genes, 22 tRNAs and 2 rRNAs with absence of atp8. Divergences of 12 protein-coding genes were as follow: 14.9% between S. theileri and S. erinaceieuropaei, 14.7% between S. theileri and S. decipiens, and 14.5% between S. theileri with S. ranarum. Divergences of 12 proteins of S. theileri and S. erinaceieuropaei ranged from 2.3% in cox1 to 15.7% in nad5, while S. theileri varied from S. decipiens and S. ranarum by 1.3% in cox1 to 15.7% in nad3. Phylogenetic relationship of S. theileri with eucestodes inferred using the maximum likelihood and Bayesian inferences exhibited identical tree topologies. A clade composed of S. decipiens and S. ranarum formed a sister species to S. erinaceieuropaei, and S. theileri formed a sister species to all species in this clade. Within the diphyllobothridean clade, Dibothriocephalus, Diphyllobothrium and Spirometra formed a monophyletic group, and sister genera were well supported.

The new species Kalloconus marimaris sp. nov. and Africonus angeluquei sp. nov. are described from the material obtained during the MNCN sampling campaigns at the Cabo Verde Islands. The new species have been characterized by examination of their shell and radular teeth morphology and by the comparison of mitochondrial genomes obtained through next-generation DNA sequencing techniques. Phylogenetic analyses suggest that K. marimaris sp. nov., known from Sal Island, is a sister species to Kalloconus ateralbus, whereas A. angeluquei sp. nov. from Maio Island is a sister species to Africonus josephinae and Africonus borgesi from Boa Vista Island. The estimated genetic distances were consistent with the full species rank for the new taxa described herein.
