Here we report the first distribution record of genus Micromeriella Betrem, 1972 (Hymenoptera, Scoliidae) from archipelago Malta, based on two specimens aurolea (Klug, 1832) collected island Gozo. Although this species is relatively well distributed in Afrotropical and Palaearctic regions, extend its to central Mediterranean islands. Molecular barcoding using cytochrome c oxidase subunit I (COI...

A new genus and species of flower flies (Diptera: Syrphidae: Syrphinae: Syrphini) are described from central Africa (Kenya & Uganda), Afrostoma quadripunctatum. A key to the Afrotropical genera of the subfamily Syrphinae is given. A review of the melanostomine [Bacchini] genera and subgenera is provided along with a key to them. Phylogenetic placement of Afrostoma is included based on mitochond...

The known subunits of yeast mitochondrial cytochrome c oxidase are reviewed. The structures of all eleven of its subunits are explored by building homology models based on the published structures of the homologous bovine subunits and similarities and differences are highlighted, particularly of the core functional subunit I. Yeast genetic techniques to enable introduction of mutations into the...

We describe "universal" DNA primers for polymerase chain reaction (PCR) amplification of a 710-bp fragment of the mitochondrial cytochrome c oxidase subunit I gene (COI) from 11 invertebrate phyla: Echinodermata, Mollusca, Annelida, Pogonophora, Arthropoda, Nemertinea, Echiura, Sipuncula, Platyhelminthes, Tardigrada, and Coelenterata, as well as the putative phylum Vestimentifera. Preliminary c...

A single open reading frame (ORF) encoding cytochrome c oxidase subunit I and II (cox1/2) was identified in the mitochondrial genome of the slime mold Dictyostelium discoideum. The cox1 coding region shares intron positions with its counterparts in fungi and algae. Northern blot analysis, using exon and intron-specific probes, suggests that the cox1/2 gene is transcribed as part of a large, eff...

The membranes from Corynebacterium glutamicum cells contain a hydrophobic di-haem C protein as the cytochrome c subunit of the new type of cytochrome bc complex (complex III in the respiratory chain) encoded by the qcrCAB operon [Sone, N., Nagata, K., Kojima, H., Tajima, J., Kodera, Y., Kanamaru, T., Noguchi, S. & Sakamoto, J. (2001). Biochim Biophys Acta 1503, 279-290]. To characterize complex...

OBJECTIVE Long-term antiretroviral treatment with nucleoside analogue reverse transcriptase inhibitors (NRTI) may result in a cardiomyopathy due to mitochondrial DNA (mtDNA) depletion. An intact mitochondrial function is required for the synthesis of intramyocardial pyrimidine nucleotides, which in turn are building blocks of mtDNA. We investigated if NRTI-related cardiomyopathy can be prevente...

Cobia, Rachycentron canadum, is the only species in family of Rachycentridae. Cobia typically characterized as having 26–33 dorsal-fin rays. However, an investigation specimens collected from Western Visayas waters revealed a wider variation ray count than previously reported, with some 35–36 Suspecting possible cryptic species, we compared mitochondrial cytochrome oxidase subunit 1 (COI) seque...

We report the first biosecurity surveillance detections of adventive cerambycid beetle Nathrius brevipennis (Mulsant) by Australian Government Department Agriculture, Fisheries and Forestry. The in panel traps near port Melbourne, Victoria, Australia are a result ongoing pest monitoring department's National Border Surveillance program. adults were detected at three separate trap sites over suc...
