With millions of species and their life-stage transformations, the animal kingdom provides a challenging target for taxonomy. Recent work has suggested that a DNA-based identification system, founded on the mitochondrial gene, cytochrome c oxidase subunit 1 (COI), can aid the resolution of this diversity. While past work has validated the ability of COI sequences to diagnose species in certain ...

The Black, Azov, Caspian and Aral Seas, remnants of the intracontinental Paratethys basin, are home to a spectacular diversity of crustaceans. This study examines the past history of the Ponto-Caspian fauna through comparative phylogeographical studies on both benthic and planktonic taxa, based on an examination of nucleotide diversity in the mitochondrial, cytochrome c oxidase subunit 1 (COI) ...

The identification of the efficiency of some mtDNA genes of Mus musculus species complex (house mouse) for biosystematics research was studied in this approach. Recent studies have made use of different mitochondrial genes including NADH dehydrogenase genes, cytochrome b gene, cytochrome oxidase genes, D-loop region and whole mtDNA genome to study the house mouse species. Usage of each of these...

Two new species of anthuroid isopods, Caenanthura koreana sp. nov. and Apanthura koreaensis sp. nov. are described from the southern and western coasts of the Korean Peninsula. A key to the species and the type locality of Caenanthura are provided. Additionally, we determined the partial sequences of the mitochondrial cytochrome c oxidase subunit 1 (CO1) from two new species.

the identification of the efficiency of some mtdna genes of mus musculus species complex (house mouse) for biosystematics research was studied in this approach. recent studies have made use of different mitochondrial genes including nadh dehydrogenase genes, cytochrome b gene, cytochrome oxidase genes, d-loop region and whole mtdna genome to study the house mouse species. usage of each of these...

The chemical and enzymatic properties of the cytochrome system in the particulate preparations obtained from dormant spores, germinated spores, young vegetative cells, and vegetative cells of Bacillus subtilis PCI219 were investigated. Difference spectra of particulate fractions from dormant spores of this strain suggested the presence of cytochromes a, a(3), b, c(+c(1)), and o. All of the cyto...

where the activity is determined by measuring the rate of oxidation of reduced cytochrome c. Smith (6, 7), Conrad (8, 9), Wainio (10-13) et ~2. have extensively investigated the effect of various factors on the cytochrome oxidase activity measured by System 2 with soluble and insoluble preparations of cytochrome oxidase, whereas among those (14-30) who have employed System 1, Slater (5), using ...

Three different cell types of Neurospora crussa deficient in cytochrome oxidase were studied : the nuclear mutant cni-1, the cytoplasmic mutant mi-1 and copper-depleted wild-type cells. 1. The enzyme-deficient cells have retained a functioning mitochondrial protein synthesis. It accounted for 1216 % of the total protein synthesis of the cell. However, the analysis of mitochondrial translation p...

1. A cytochrome oxidase-rich submitochondrial membrane (green membrane) was obtained from beef heart mitochondria after extraction of flavoproteins, cytochrome b, Cll C, etc. by treating with deoxycholate and potassium chloride. 2. The green membrane was formed by self assembly from the membrane fragments (flat sheets), which derived from the cristae membrane of mitochondria and had essentially...
