Dna Phylogeny

A cladistic analysis of nucleotide substitutions in the 16S ribosomal RNA and cytochrome oxidase subunit I genes of mitochondrial DNA does not support the monophyly of species within each of the ‘lalandii’ and ‘frontalis’ subgroups of Jasus; the subgroupings may need revision. The recently described species J. caveorum is most closely related to J. tristani and J. paulensis, and not to J. frontalis with which it shares an eastern South Pacific distribution and morphological similarity. Two species, J. tristani and J. paulensis, are so genetically similar that further genetic, morphological and behavioural analyses are needed to assess their status as separate species.

Extensive Data

The phylogeny of Rhyacophilidae was explored with 28S ribosomal RNA (rRNA) and Cytochrome Oxidase Subunit I (COI) mitochondrial DNA (mtDNA). Eighty one rhyacophilids were included in the analysis. We found that although Rhyacophilidae was recovered as monophyletic, intrafamilial relationships are not well-resolved using this dataset. Bootstrap support was poor for intrageneric relationships and additional data will be required to present a more robust hypothesis. The recovered phylogeny places Fansipangana as the sister taxon of the rest of Rhyacophilidae. We found that Himalopsyche was nested inside the genus Rhyacophila with the verrula group sister to Himalopsyche and remaining Rhyacophila. These results and possible relationships should be tested with a more extensive data set.

Undescribed females representing four morphological types were found in a collection of adult Diamesa from about 5000 m altitude in Rongbuk, Tibet. Short DNA sequences of cytochrome oxidase subunit 2 were used to associate two single males in the material with conspecific females. Diamesa solhoyi n.sp. and Diamesa aculeata n.sp. are described. The complete type material and additional specimens have been deposited in the Insect Collection at the Institute of Zoology, Academia Sinica, Beijing (IZAS). The sequences are deposited in Genbank with accession numbers AM051227–AM051233.

The taxonomy within the genus Centrophorus has been controversial almost since its origin, raising uncertainties about the identification, the phylogenetic placement and the geographical distribution of several species. The partial nucleotide sequences of two mitochondrial DNA gene regions, the cytochrome c oxidase subunit I and the 16S ribosomal RNA, genetically confirmed the presence of the little gulper shark in Cypriot waters. The species presence in the Mediterranean Sea is revised and discussed.

Mitochondrial Dna Inheritance

AbstractThe aim of the study was to describe the mechanism of mitochondrial DNA inheritance in a group of farmed raccoon dogs. The study involved 354 individuals. Whole peripheral blood was the research material. DNA was isolated and PCR was performed for two fragments of mitochondrial genes: COX1 (cytochrome oxidase subunit 1 gene) and COX2 (cytochrome oxidase subunit 2 gene). The PCR products were sequenced and subjected to bioinformatics analyses. Three mitochondrial haplotypes were identified in the COX1 gene fragment and two in the COX2 gene fragment. The analysis of mtDNA inheritance in the paternal line confirmed the three cases of paternal mtDNA inheritance, i.e. the so-called “paternal leakage” in the analysed population. In two families, all offspring inherited paternal mitochondrial DNA, whereas in one family one descendant inherited paternal mtDNA and another one inherited maternal mtDNA. The lineage data indicated that one female which inherited maternal mitochondrial DNA transferred it onto the next generation. To sum up, the results of the study for the first time demonstrated the phenomenon of “paternal leakage” in farmed raccoon dogs, which facilitated description of mitochondrial DNA inheritance in the paternal line.
