To study the phylogenetic relationships among Anseriformes, sequences for the complete mitochondrial control region (CR) were determined from 45 waterfowl representing 24 genera, i.e., half of the existing genera. To confirm the results based on CR analysis we also analyzed representative species based on two mitochondrial protein-coding genes, cytochrome b (cytb) and NADH dehydrogenase subunit...

In the mid 1990s cytochrome b and other mitochondrial DNA data reinvigorated cetacean phylogenetics by proposing many novel and provocative hypotheses of cetacean relationships. These results sparked a revision and reanalysis of morphological datasets, and the collection of new nuclear DNA data from numerous loci. Some of the most controversial mitochondrial hypotheses have now become benchmark...

The availability of mitochondrial genome sequences is growing as a result of recent technological advances in molecular biology. In phylogenetic analyses, the complete mitogenome is increasingly becoming the marker of choice, usually providing better phylogenetic resolution and precision relative to traditional markers such as cytochrome b (CYTB) and the control region (CR). In some cases, the ...

BACKGROUND The aim of this study was to assess the effect of antiretroviral therapy (ART) versus HIV on mitochondria in fat. METHODS Subcutaneous fat was collected from 45 HIV-infected patients on ART with lipoatrophy, 11 HIV-infected ART-naive patients and nine healthy controls. Three mitochondrial transcripts: NADH dehydrogenase subunit 1 (ND1), cytochrome B (CYTB) and NADH dehydrogenase su...

The present study was carried out to validate the single nucleotide polymorphism (SNP) in mitochondrial gene- cytochrome b oxidase at 14,716 bp (C T transition) position obtained from whole genome sequence data of indigenous cattle breeds Department Animal Genetics and Breeding, Madras Veterinary College, Tamil Nadu. A total 288 animals, viz. Alambadi (16), Bargur (99), Kangayam (54), Pulikulam...

The Praomyini tribe is one of the most diverse and abundant groups of Old World rodents. Several species are known to be involved in crop damage and in the epidemiology of several human and cattle diseases. Due to the existence of sibling species their identification is often problematic. Thus an easy, fast and accurate species identification tool is needed for non-systematicians to correctly i...

Previous studies on the phylogenetic relationships between lamprey species relied either a low number of morphological characters related to feeding apparatus, or molecular mitochondrial DNA markers. Here, we apply multilocus approach assess northern hemisphere lampreys, with special emphasis 17 European species. The study comprises two (cytochrome c oxidase subunit 1 gene—DNA barcodes, and cyt...
