The upper reaches of the Yangtze River (upper YR) are a biological zone with extremely rich fish diversity, especially endemic fish. However, long-term human interference, such as environmental pollution and cascade hydropower construction, has significantly changed habitat many is threatening number genetic diversity populations. Jinshaia sinensis typical small but rare that found in YR, its s...

Mitochondrial cytochrome c is a water-soluble protein in the intermembrane space which catalyzes electron transfer from the cytochrome bc1 complex to the terminal oxidase cytochrome aa3. In Bradyrhizobium japonicum, a gene (cycM) which apparently encodes a membrane-anchored homolog of mitochondrial cytochrome c was discovered. The apoprotein deduced from the nucleotide sequence of the cycM gene...

Atovaquone is a new anti-malarial agent that specifically targets the cytochrome bc1 complex and inhibits parasite respiration. A growing number of failures of this drug in the treatment of malaria have been genetically linked to point mutations in the mitochondrial cytochrome b gene. To better understand the molecular basis of atovaquone resistance in malaria, we introduced five of these mutat...

The phylogenetic relationships among seven Callosciurus species from the Indochina Peninsula, including C. honkhoaiensis which is endemic to Hon Khoai Island, were studied using complete mitochondrial cytochrome b gene sequences (1140 bases). We primarily focused on position of pygerythrus, distributed in western part peninsula. identified two main lineages: 1) caniceps, honkhoaiensis, inornatu...

Abstract The East European vole Microtus mystacinus is the most widespread species in Anatolia. It also frequently seen watery habitats a large area of Eurasia. In this paper, an attempt was made to ascertain level genetic differentiation between Anatolian (Asian part Turkey) and Turkish Thracian (European populations together with additional data from other parts Asia Europe by analysing two m...

The ATP-dependent PIM1 protease, a Lon-like protease localized in the mitochondrial matrix, is required for mitochondrial genome integrity in yeast. Cells lacking PIM1 accumulate lesions in the mitochondrial DNA (mtDNA) and therefore lose respiratory competence. The identification of a multicopy suppressor, which stabilizes mtDNA in the absence of PIM1, enabled us to characterize novel function...

Mice homozygous for a defect in the PTCD2 (pentatricopeptide repeat domain protein 2) gene were generated in order to study the role of this protein in mitochondrial RNA metabolism. These mice displayed specific but variable reduction of ubiquinol-cytochrome c reductase complex activity in mitochondria of heart, liver and skeletal muscle due to a decrease in the expression of mitochondrial DNA-...

Barilius bendelisis is an important food fish and a demanding ornamental species in India. Despite its great economic importance, several wild populations have been suffering drastic reduction. The genetic variability within population is extremely useful for gathering information on individual’s identity, breeding patterns, degree of relatedness and disturbance of genetic variation among them....

background: the adult female sand flies (diptera: psychodidae) of the subgenus larroussius are important vectors of leishmania infantum (kinetoplastida: tripanosomatidae) in meshkinshahr district, northwest of iran. four phle­boto­mus ( larroussius ) species are present in this area, i.e. phlebotomus ( larroussius ) kandelakii , p. ( la. ) major , p. ( la. ) perfiliewi and p. ( la. ) tobbi . th...

Rodents from the subfamily Gerbillinae Gray, 1825, are an important component of small fauna in arid and desertic regions Africa Asia. Among this group rodents, Sundevall’s jird, Meriones crassus, is one most widespread desert species, found countries ranging Morocco to Pakistan. In study, we sequenced cytochrome b gene mitochondrial DNA two specimens captured Morocco, constituting first geneti...
