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...
background: interest in tatera indica rodent arises mostly because it is believed that this species is survived among four subspecies reported from iran, two of which exist in khuzestan province. in addition, it might has a role as reservoir hosts of zoonotic cutaneous leishmaniasis in the transmission of leishmania major in some of the widespread asian foci including southwestern iran. method...
Very slight sequence differences in the mitochondrial cytochrome b gene, even single nucleotide substitutions, have been proposed as indicative of different species of avian malaria parasites. However, few studies have examined within-species variation in that gene for Plasmodium or related genera. We examined sequences for the entire cytochrome b gene from Plasmodium mexicanum , a parasite of ...
Alcanivorax borkumensis is a marine bacterium that has ability to grow on limited substrates that mainly is alkanes. The ability to use wide range of hydrocarbons is advantage of this bacterium to other marine community bacteria. A. borkumensis have two genetic systems for alkane biodegradation. The First system is alkane hydroxylase (alk-B1and alk-B2) and the second system is...
We investigated phylogenetic relationships among five species of Japanese brown frogs by the analysis of nucleotide sequences in the cytochrome b gene of mitochondrial DNA (mtDNA). The sequence of the 251-base pairs, which cover approximately 22% of the cytochrome b gene, was determined by PCR-Direct sequencing method. Phylogenetic relationships were analyzed by UPGMA, neighbor-joining, maximum...
Respiratory defective mutants of Saccharomyces cerevisiae assigned to complementation group G28 display a deficiency, in the respiratory chain complex coenzyme QH2-cytochrome c reductase. The mutants define a new nuclear gene, designated CBP3, required for the assembly of the complex. Mutations in CBP3 are expressed in the absence of spectrally and immunologically detectable cytochrome b, a cat...
The cytochrome c maturation system influences the expression of virulence factors in Bacillus anthracis. B. anthracis carries two copies of the ccdA gene, encoding predicted thiol-disulfide oxidoreductases that contribute to cytochrome c maturation, while the closely related organism Bacillus subtilis carries only one copy of ccdA. To investigate the roles of the two ccdA gene copies in B. anth...
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...
