RFLP analysis of mitochondrial DNA (mtDNA) was used to study variation within 13 populations of #Clarias batrachus$, sampled respectively in Vietnam, Thailand and in the Indonesian Archipelago. In this study an amplified region corresponding approximately to 2.3 kilobases of the Cytochrome-b and D-loop genes was digested using 8 restriction enzymes...
We developed a DNA assay for bloodmeal identification in haematophagous insects. Specific host cytochrome B gene sequences were amplified by PCR and classified on the basis of their mobility in a heteroduplex assay. In the blackfly #Simulium damnosum s.l.$ (#Diptera$ : #Simuliidae$), human cytochrome B DNA sequences were identifiable up to 3 days f...

The Mormyridae are African osteoglossomorph fresh-water fishes of great interest because of their electric organs. They have become an important model in studies of electrophysiology and behavior but their phylogenetic relationships are poorly known. Phylogenetic relationships among mormyrids were determined by comparing cytochrome b sequences (588...
LA FAMILLE DES TIMALIIDAE, LES TIMALIES, EST UN GROUPE IMPORTANT AU SEIN DES PASSEREAUX INSECTIVORES DE L'ANCIEN MONDE. ELLE COMPREND PLUS DE 200 ESPECES PRINCIPALEMENT FORESTIERES, DISTRIBUEES POUR LA PLUS GRANDE PARTIE EN ASIE DU SUD-EST, ET PRESENTANT UNE GRANDE DIVERSITE MORPHOLOGIQUE ET ECOLOGIQUE. EN L'ABSENCE DE DIAGNOSE PRECISE, DE NOMBREUX...
Molecular markers allow insights into the population biology and ecology of deep-sea organisms, which are usually hardly accessible to direct observation and poorly known. Such a study was undertaken here for the deep-sea fish Beryx splendens, a species of growing interest to fisheries. B. splendens populations were sampled on seamounts and contine...

LE CYTOCHROME B 5 5 8 DU COMPLEXE DE LA NADPH OXYDASE GENERE DES IONS SUPEROXYDE GRACE A UN TRANSFERT D'ELECTRONS DU NADPH VERS L'OXYGENE. LA NADPH OXYDASE DORMANTE ET DISSOCIEE DANS LES CELLULES AU REPOS DEPEND POUR FONCTIONNER DE L'ASSEMBLAGE DE PROTEINES CYTOSOLIQUES (P47-PHOX, P67-PHOX, P40-PHOX ET RAC) SUR LE CONSTITUANT MEMBRANAIRE REDOX, LE ...
A fragment of the cytochrome b gene was analysed by PCR/SSCP in Decapterus russelli samples from the Indo-Malay archipelago. Sequence analysis revealed two distinct mitochondrial clades (mean nucleotide divergence=2.2%) whose geographic distribution was heterogeneous (Nei's GST=0.416), pointing to a complex pattern of genetic differentiation and de...
