A real-time qPCR assay was designed to detect African-derived subspecies of western honey bees (Apis mellifera L.). The probes targeted the same region mitochondrial cytochrome b gene used in previous restriction enzyme assays. Using samples from 16 A. representing four lineages, we evaluated efficacy this identify African- (or A-lineage) and non-A-lineage bees. successfully differentiated A-li...

Abstract Mitochondrial DNA cytochrome oxidase (COI) and microsatellite loci were used to better explain the speciation events, history of hybridization, genetic population structure stone crabs Menippe adinaWilliams & Felder, 1986 M. mercenaria (Say, 1817–1818). A survey a 670-bp COI sequence 711 collected from Texas North Carolina Belize, Central America showed presence two well-defined mt...

Our study evaluated in silico the potential of 14 mitochondrial genes encoding the subunits of the respiratory chain complexes, including cytochrome c oxidase I (CO1), as Basidiomycota DNA barcode. Fifteen complete and partial mitochondrial genomes were recovered and characterized in this study. Mitochondrial genes showed high values of molecular divergence, indicating a potential for the resol...

Acipenser stellatus (stellate sturgeon) represents a sturgeon species of great importance for the scientific community and fishermen that has been intensively captured for decades. Besides of overfishing and poaching, their reproduction sites have been destroyed and their natural habitats were affected by pollution. In consequence, wild populations of stellate sturgeon have decreased dramatical...

Serpulidae Rafinesque, 1815 is a speciose group of polychaetes that all inhabit calcareous tubes. The family was traditionally subdivided into Serpulinae, Filograninae, and Spirorbinae. Recent phylogenetic analyses have suggested both Filograninae Serpulinae are paraphyletic, though with limited sampling. Here we report the first analysis based on comprehensive sampling genera (though excluding...

We reconstructed a phylogeny for the seven species of doves in the genus Zenaidu on the basis of a combined analysis of mitochondrial (ND2 and cytochrome b) and nuclear (fibrinogen intron 7) DNA sequences. This phylogeny, which is completely resolved, is well supported with all nodes showing greater than 50% bootstrap support. There was no significant conflict between trees based on each gene i...

BACKGROUND The mitochondrial DNA depletion syndrome is an autosomal recessive disorder of infancy or childhood characterized by decreased mitochondrial DNA copy number in affected tissues. Mutations in 2 genes involved in deoxyribonucleotide metabolism, the deoxyguanosine kinase gene (DGK) and the thymidine kinase 2 gene (TK2), have been related to this syndrome. OBJECTIVE To describe 3 sibli...

Abstract Grasshopper mice of the genus Onychomys, represented by three living species in North America, have a long and controversial taxonomic history. Usually allocated to either cricetine or neotomine cricetids, they also been considered represent distinct tribe. Since discovery description extinct grasshopper mouse relative Acrolophomys rhodopetros from late Miocene upper Dove Spring Format...

The morphological variation, extended distribution, and sequence divergence of a recently described cobra Naja fuxi Shi et al., 2022 captured from mountainous areas in Thailand are evaluated by using molecular analyses. We investigated the genetic variation affinities 72 specimens genus mitochondrial DNA (cytochrome b control region) nuclear gene, C-mos. Morphological examination was conducted ...

The mRNAs from two yeast mitochondrial genes cob-box (cytochrome b) and oxi-3 (cytochrome oxidase 40,000 dalton subunit) are processed from large (7-10 kb) precursors. Certain mutations in each gene block the maturation of the RNAs from both genes at a variety of specific steps. The pleiotropic cytochrome b mutants seem to lack a functional trans-acting RNA required for the processing of both m...
