Le traitement mutagène par rayons gamma ou par methyl sulfonate d’éthyle, de grains de mais à cytoplasme mâle stérile Texas a permis d’obtenir des plantes mâle fertiles résistantes à Helminthosporium maydis race T. L’hérédité de ces deux caractères est cytoplasmique. L’étude du DNA mitochondrial natif de 5 descendances mâle fertiles résistantes montre qu’aucun de nos mutants, pas plus que le témoin à cytoplasme Texas, ne possède la molécule de DNA de 2,35 kb qui caractérise les cytoplasmes N, C et S. Donc, comme les révertants obtenus par culture in vitro, les types A mâle-fertiles ont un DNA natif mitochondrial qui migre à la manière du type Texas. Les diagrammes électrophorétiques du DNA mitochondrial digéré par diverses enzymes de restriction sont... |

Des souches d’Ustilago nuda, agent du charbon nu de l’orge, résistantes à la carboxine ont été détectées en France et dans d’autres pays européens. Une résistance croisée positive s’observe entre ce fongicide, le fenfuram, la pyracarbolide et divers autres analogues structuraux ; le mépronil se singularise car il est plus toxique pour les isolats résistants à la carboxine que pour les isolats sensibles. Toutes les souches sont affectées de la même manière par l’antimycine A, l’azide de sodium, le 2,4- dinitrophénol, le fentin-acétate, la 8-hydroxyquinoléine et le thénoyltrifluoroacétone qui, comme la carboxine, agissent au niveau des mitochondries. |

CATdb is a free resource available at http://urgv.evry.inra.fr/CATdb that provides public access to a large collection of transcriptome data for Arabidopsis thaliana produced by a single Complete Arabidopsis Transcriptome Micro Array (CATMA) platform. CATMA probes consist of gene-specific sequence tags (GSTs) of 150500 bp. The v2 version of CATMA contains 24 576 GST probes representing most of the predicted A. thaliana genes, and 615 probes tiling the chloroplastic and mitochondrial genomes. Data in CATdb are entirely processed with the same standardized protocol, from microarray printing to data analyses. CATdb contains the results of 53 projects including 1724 hybridized samples distributed between 13 different organs, 49 different developmental... |

Studies of mitochondrial DNA sequences in a variety of animals have shown important differences between phyla, including differences in the genetic codes used, and varying constraints on base composition. In that respect, little is known of mites, an important and diversified group. We sequenced a portion (340 nt) of the cytochrome oxidase subunit I (COI) encoding gene in twenty species of phytophagous mites belonging to nine genera of the two families #Tetranychidae$ and #Tenuipalpidae$. The mitochondrial genetic code used in mites appeared to be the same as in insects. As is generally also the case in insects, the mite sequences were very rich in A + T (75% on average), especially at the third codon position (94%). However, important variations of base... |

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 (HinfI, Hin6I, MvaI, MspI, HaeIII, BanHI, NdeII, DraI). 12 mtDNA haplotypes were found in 40 specimens. Each sampling location was characterised by one haplotype, except Palembang (Sumatra, Indonesia) and Samarinda (Kalimantan, Indonesia) where 2 and 4 haplotypes were found respectively. The consensus tree calculated from 15 more parsimonious networks showed that mtDNA haplotypes are geographically distributed.... |

Background: The hydrogenosomes of the anaerobic ciliate Nyctotherus ovalis show how mitochondria can evolve into hydrogenosomes because they possess a mitochondrial genome and parts of an electron-transport chain on the one hand, and a hydrogenase on the other hand. The hydrogenase permits direct reoxidation of NADH because it consists of a [ FeFe] hydrogenase module that is fused to two modules, which are homologous to the 24 kDa and the 51 kDa subunits of a mitochondrial complex I.Results: The [ FeFe] hydrogenase belongs to a clade of hydrogenases that are different from well-known eukaryotic hydrogenases. The 24 kDa and the 51 kDa modules are most closely related to homologous modules that function in bacterial [ NiFe] hydrogenases. Paralogous,... |

The relationship between pheromone composition and mitochondrial haplotype clades was investigated by coupling DNA analyses with pheromone identification and male mate searching behavior among different geographic populations of Busseola fusca. The within-population variations in pheromone blend were as great as those observed between geographic populations, suggesting that the female sex pheromone blend was not the basis of reproductive isolation between the geographic clades. Furthermore, while data from wind tunnel experiments demonstrated that most of the tested males were sensitive to small variations in pheromone mixture, there was considerable within-population variability in the observed response. The study identified a new pheromone component,... |
