The chamois provides an excellent model for exploring the effect of historical and evolutionary events on diversification. We investigate cytochrome b (cytb) sequences in the 10 recognized subspecies of Rupicapra classified within 2 species: Rupicapra pyrenaica, with the subspecies parva, pyrenaica, and ornata, and Rupicapra rupicapra, with cartusiana, rupicapra, tatrica, carpatica, balcanica, ...

Reduced oxygenation of a variety of cells results in transcriptional upregulation of several genes, including the hematopoietic hormone erythropoietin, the angiogenic vascular endothelial growth factor (VEGF), and glycolytic enzymes such as aldolase. Recently, the heme protein cytochrome b558 of the nicotinamide adenine dinucleotide phosphate (NADPH) oxidase complex has been proposed as a key c...

The genetic structure of seven mainland and island Asian populations of Bombus ignitus was investigated using nine microsatellite markers and the sequences of part of the mitochondrial cytochrome b (cytb) gene. While microsatellite markers showed high genetic variability, no sequence variation was found in the cytb gene fragment analyzed. The number of microsatellite alleles ranged from 9 to 24...

A prerequisite for reliable detection of low-density Plasmodium infections in malaria pre-elimination settings is the availability of ultra-sensitive and high-throughput molecular tools. We developed a SYBR Green real-time PCR restriction fragment length polymorphism assay (cytb-qPCR) targeting the cytochrome b gene of the four major human Plasmodium species (P. falciparum, P. vivax, P. malaria...

BACKGROUND The mitochondrial gene COI has been widely used by taxonomists as a standard DNA barcode sequence for the identification of many animal species. However, the COI region is of limited use for identifying certain species and is not efficiently amplified by PCR in all animal taxa. To evaluate the utility of COI as a DNA barcode and to identify other barcode genes, we chose the aphid sub...

Anemonefishes (Pomacentridae Amphiprioninae) are a group of 30 valid coral reef fish species with their phylogenetic relationships still under debate. The eight available mitogenomes of anemonefishes were used to reconstruct the molecular phylogenetic tree; six were obtained from this study (Amphiprion clarkii, A. frenatus, A. percula, A. perideraion, A. polymnus and Premnas biaculeatus) and tw...

In visceral leishmaniasis, the detection of the agent is of paramount importance to identify reservoirs of infection. Here, we evaluated the diagnostic attributes of PCRs based on primers directed to cytochrome-B (cytB), cytochrome-oxidase-subunit II (coxII), cytochrome-C (cytC), and the minicircle-kDNA. Although PCRs directed to cytB, coxII, cytC were able to detect different species of Leishm...

Rieske/cytochrome b (Rieske/cytb) complexes are proton pumping quinol oxidases that are present in most bacteria and Archaea. The phylogeny of their subunits follows closely the 16S-rRNA phylogeny, indicating that chemiosmotic coupling was already present in the last universal common ancestor of Archaea and bacteria. Haloarchaea are the only organisms found so far that acquired Rieske/cytb comp...

A new species of Docosia Winnertz, Docosia dentata sp. n., is described and illustrated, based on a single male specimen collected in Muránska planina National Park in Central Slovakia. DNA sequences (COI, COII, CytB, and ITS2) are included and compared for 13 species of Docosia. There was found only little congruence between the molecular results and previous scarce data about interspecific re...

Methods Relationships of the five species of Hypomesus from throughout the North Pacific were reconstructed through maximum likelihood and Bayesian phylogenetic analyses of sequence data from two mitochondrial (cytb, 16S) and three nuclear (ITS2, S71, RAG1) gene regions of five to 25 individuals per species, totalling 3588 characters. The resulting phylogenies were used to test hypotheses of sp...
