| The sequencing of prfA, encoding the transcriptional regulator of virulence genes, in 26 low virulence field Listeria monocytogenes strains showed that eight strains exhibited the same single amino-acid substitution: PrfAK220T. These strains exhibited no expression of PrfA-regulated proteins and thus no virulence. This substitution inactivated PrfA, since expression of the PrfAK220T mutant gene in an EGDΔprfA strain did not restore the haemolytic and phosphatidylcholine phospholipase C activities, in contrast to the wild-type prfA gene. The substitution of the lysine at position 220 occurred in the helix αH. However, the data showed that the PrfAK220T protein is dimerized just as well as its wild-type counterpart, but does not bind to PrfA boxes.... |

| Une méthode non-aqueuse améliorée pour la préparation d'ADN chloroplastique (ADNcp) à partir de matériel foliaire séché de plantes adultes a permis une analyse des PLFR de l'ADNcp du riz à l'aide de 10 endonucléases de restriction. 320 plantes, représentant 248 variétés et 15 espèces de la Section #Eu-Oryza$ du genre #Oryza$, furent analysées. Un phylogramme hypothétique complet de 32 types de plastomes, dont 10 parmi les riz cultivés, fut déduit d'une analyse cladistique de 112 mutations décelées, calibré à l'aide de données bibliographiques sur les taux de mutation de l'ADNcp chez les Graminées, et confronté à certains repères paléo-géographiques. Les résultats apportent des informations nouvelles, en bonne partie compatibles avec les données existantes... |

| 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... |

| Background: The first high quality draft of the grape genome sequence has just been published. This is a critical step in accessing all the genes of this species and increases the chances of exploiting the natural genetic diversity through association genetics. However, our basic knowledge of the extent of allelic variation within the species is still not sufficient. Towards this goal, we constructed nested genetic core collections (G-cores) to capture the simple sequence repeat (SSR) diversity of the grape cultivated compartment (Vitis vinifera L. subsp. sativa) from the world's largest germplasm collection (Domaine de Vassal, INRA Herault, France), containing 2262 unique genotypes. Results: Sub-samples of 12, 24, 48 and 92 varieties of V. vinifera L.... |

| The interactions between the effects of three plumage color mutations taken two-by-two (sex-linked recessive roux,autosomal recessive lavender, and autosomal dominant beige) were studied in Japanese quail by producing a total of 121 F1and 1118 F2 quail from the three pure stocks. Three new plumage colors were obtained in F2 quail: roux-diluted beige,cream, and lavender-diluted beige. Two of them, roux-diluted beige (from the roux and beige mutations) and cream (fromthe roux and lavender mutations) corresponded to double homozygotes or hemizygous birds, and could therefore be usedto tag a quail line. On the other hand, an F3 from F2 birds with lavender-diluted beige plumage was necessary to show thatquail with this plumage color were homozygous for the... |
