Mitochondrial cytochrome b sequence data from 15 species of herons (Aves: Ardeidae), representing 13 genera, were compared with DNA hybridization data of single-copy nuclear DNA (scnDNA) from the same species in a taxonomic congruence assessment of heron phylogeny. The two data sets produced a partially resolved, completely congruent estimate of phylogeny with the following basic structure: (Ti...

Snakehead fish with different geographical differences can have an impact on genetic diversity. DNA barcoding is a system designed to identify species precisely and accurately by using short standardized gene regions. This study aims determine the diversity of snakehead populations in four areas East Java. used Cytochrome b (Cyt b) sequence mitochondrial variation wild population Channa striata...

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...

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...

The biogenesis of multimeric protein complexes of the inner mitochondrial membrane in yeast requires a number of nuclear-coded ancillary proteins. One of these, Pet100p, is required for cytochrome c oxidase. Previous studies have shown that Pet100p is not required for the synthesis, processing, or targeting of cytochrome c oxidase subunits to the mitochondrion nor for heme A biosynthesis. Here,...

bemisia tabaci (gennadius) (hemiptera: aleyrodidae), is one of the most important pest of vegetable and fruit crops. this polyphagous pest has a range of natural enemies including the parasitoid eretmocerus mundus (merect) (hymenoptera: aphelinidae). to determine the molecular profile and taxonomic status of iranian isolates of e. mundus, parasitized b. tabaci samples were collected from cotton...

Veritable identification and differentiation of avian species is a vital step in conservative, taxonomic, forensic, legal and other ornithological interventions. Therefore, this study involved the application of molecular approach to identify some avian species i.e. Chicken (Gallus gallus), Muskovy duck (Cairina moschata), Japanese quail (Coturnix japonica), Laughing dove (Streptopelia senegale...

The reintroduction of the extinct beluga sturgeon (Huso huso L.), an anadromous species with economic and traditional relevance, is a priority in next conservation strategies Northern Italy. EU-LIFE NATURA project aims to reintroduce Po River basin through captive breeding program. Critical requirements for success program are river connectivity knowledge genetic diversity selected broodstocks ...

Biogenesis of respiratory chain complexes depends on the expression of mitochondrial-encoded subunits. Their synthesis occurs on membrane-associated ribosomes and is probably coupled to their membrane insertion. Defects in expression of mitochondrial translation products are among the major causes of mitochondrial disorders. Mdm38 is related to Letm1, a protein affected in Wolf-Hirschhorn syndr...
