Expressed sequences tags of the anther smut fungus, Microbotryum violaceum, identify mating and pathogenicity genes Inra
Yockteng, R.; Marthey, S.; Chiapello, H.; Gendrault, A.; Hood, M.E.; Rodolphe, F.; Devier, B.; Wincker, P.; Dossat, C.; Giraud.
The basidiomycete fungus Microbotryum violaceum is responsible for the anther-smut disease in many plants of the Caryophyllaceae family and is a model in genetics and evolutionary biology. Infection is initiated by dikaryotic hyphae produced after the conjugation of two haploid sporidia of opposite mating type. This study describes M. violaceum ESTs corresponding to nuclear genes expressed during conjugation and early hyphal production.ResultsA normalized cDNA library generated 24,128 sequences, which were assembled into 7,765 unique genes; 25.2% of them displayed significant similarity to annotated proteins from other organisms, 74.3% a weak similarity to the same set of known proteins, and 0.5% were orphans. We identified putative pheromone receptors and...

Leptin downregulates heat shock protein-70 (HSP-70) gene expression in chicken liver and hypothalamus Inra
Figueiredo, D.; Gertler, A.; Cabello, G.; Decuypere, E.; Buyse, J.; Dridi, S..
Heat shock protein (HSP)-70 is expressed in normal and stressed cells but is highly stress-inducible. Although leptin has long been suggested to be involved in the regulation of stress response, its interaction with the HSP-70 gene is still unknown, under both unstressed and stressed conditions. The present study has aimed to investigate the effect of leptin on HSP-70 gene expression in normal chicken liver, hypothalamus, and muscle. Continuous infusion of recombinant chicken leptin (8 mu g/kg per hour) at a constant rate of 3 ml/h for 6 h in 3-week-old broiler chickens significantly (P < 0.05) decreased food intake and HSP-70 mRNA levels in liver and hypothalamus, but not in muscle. In an attempt to discriminate between the effect of leptin and of...

Mitochondrial activity regulates myoblast differentiation by control of c-Myc expression Inra
Seyer, P.; Grandemange, S.; Busson, M.; Carazo, A.; Gamaléri, F.; Pessemesse, L.; Casas, F.; Cabello, G.; Wrutniak-Cabello, C..
We have previously shown that mitochondrial activity is an important regulator of myoblast differentiation, partly through processes targeting myogenin expression. Here, we investigated the possible involvement of c-myc in these processes. Inhibition of mitochondrial activity by chloramphenicol abrogated the decrease in c-myc mRNA and protein levels Occurring at the onset of terminal differentiation. Conversely, stimulation of mitochondrial activity by overexpression of the T3 mitochondrial receptor(p43) down-regulated c-myc expression. In addition, c-myc overexpression mimicked the influence of mitochondrial activity inhibition on myoblast differentiation. Moreover, like chloramphenicol, c-myc overexpression strongly inhibited the myogenic influence of...

Plant gene expression during effective and ineffective nodule development of the tropical stem-nodulated legume Sesbania rostrata IRD
Lajudie, Philippe de; Huguet, T..
Nous avons étudié au niveau transcriptionnel l'expression des gènes de la plante au cours de la symbiose #Sesbania rostrata$ - #Azorhizobium$ ou #Rhizobium$, en comparant les profils électrophorétiques en deux dimensions des produits de traduction in vitro des ARN polyA+ provenant de racines et tiges non infectées avec ceux de nodules de racines et de tige. Parmi 25 gènes dont l'expression est stimulée dans les nodules, 16 sont spécifiques à la fois des nodules de tige et de racine, dont 6 correspondent aux leghémoglobines. L'expression de ces gènes spécifiques est séquentielle au cours du développement nodulaire. #Azorhizobium$ et #Rhizobium$ élicitent l'expression quasi identique des gènes de la plante. Enfin l'utilisation des mutants bactériens affectés...

Plant gene expression in effective and ineffective root nodules of alfalfa (Medicago sativa) IRD
Lullien, V.; Barker, D.G.; Lajudie, Philippe de; Huguet, T..
L'expression des gènes de la plante impliqués dans la symbiose #Rhizobium meliloti$ a été étudiée en comparant des profils électrophorétiques en deux dimensions des produits de traduction des ARN polyA+ provenant de nodules et de racines. Nous avons détecté 13 produits de traduction spécifiques des nodules, dont les leghémoglobines, qui apparaissent entre le neuvième et le douzième jour après inoculation ; des expériences en Northern utilisant comme sonde uncADN de leghémoglobine ont confirmé ce résultat. L'analyse de trois types différents de nodules inefficients dont le développement est arrêté à divers stades permet de conclure que : la transcription de 11 des gènes spécifiques, dont les leghémoglobines, est indépendante de l'activité fixatrice d'azote...

Revealing the dynamics of gene expression during embryonic genome activation and first differentiation in the rabbit embryo with a dedicated array screening Inra
Leandri, R.; Archilla, C.; Bui, L.C.; Peynot, N.; Liu, Z.; Cabau, C.; Chastellier, A.; Duranthon, V.; Renard, J.P..
Early mammalian development is characterized by extensive changes in nuclear functions that result from epigenetic modifications of the newly formed embryonic genome. While the first embryonic cells are totipotent, this status spans only a few cell cycles. At the blastocyst stage, the embryo already contains differentiated trophectoderm cells and pluripotent inner cell mass cells. Concomitantly, the embryonic genome becomes progressively transcriptionally active. During this unique period of development, the gene expression pattern has been mainly characterized in the mouse, in which embryonic genome activation (EGA) spans a single cell cycle after abrupt epigenetic modifications. To further characterize this period, we chose to analyze it in the rabbit,...
