A factor model to analyze heterogeneity in gene expression Inra
Blum, A.; Le Mignon, G.; Lagarrigue, S.; Causeur, D..
Background: Microarray technology allows the simultaneous analysis of thousands of genes within a singleexperiment. Significance analyses of transcriptomic data ignore the gene dependence structure. This leads tocorrelation among test statistics which affects a strong control of the false discovery proportion. A recent methodcalled FAMT allows capturing the gene dependence into factors in order to improve high-dimensional multiple testingprocedures. In the subsequent analyses aiming at a functional characterization of the differentially expressed genes,our study shows how these factors can be used both to identify the components of expression heterogeneity and togive more insight into the underlying biological processes.Results: The use of factors to...

Genomic regions involved in productivity of two specific poplar families in Europe. 2. Biomass production and its relationships with tree architecture and phenology Inra
Marron, N.; Storme, V.; Dillen, S.Y.; Bastien, C.; Ricciotti, L.; Salani, F.; Sabatti, M.; Rae, A.M.; Ceulemans, R.; Boerjan, W..
Short-rotation coppice of hybrid poplar is a promising renewable feedstock for biofuel production. Breeding for high biomass in short-rotation coppice has started only recently. Two hybrid poplar families were grown at two sites in Europe and phenotyped for a variety of biomass-related traits (1) to examine the extent of phenotypic and genetic variation in biomass production, ramification, resprouting, and phenology, (2) to search for genomic regions involved in productivity, and (3) to determine the effect of the environment on the expression of these traits. The performance of both families differed within and among sites. A pronounced heterosis was observed in most cases. Moderate to high heritability values were found. Seventeen quantitative trait loci...

Low level of polymorphism in two putative NPR1 homologs in the Vitaceae familily Inra
Bergeault, K.; Bertsch, C.; Merdinoglu, D.; Walter, B..
BackgroundGrapevine is subjected to numerous pests and diseases resulting in the use of phytochemicals in large quantities. The will to decrease the use of phytochemicals leads to attempts to find alternative strategies, implying knowledge of defence mechanisms. Numerous studies have led to the identification of signalling pathways and regulatory elements involved in defence in various plant species. Nonexpressor of Pathogenesis Related 1 (NPR1) is an important regulatory component of systemic acquired resistance (SAR) in Arabidopsis thaliana.ResultsTwo putative homologs of NPR1 gene were found in the two sequenced grapevine genomes available in the Genoscope database for line 40024 and in the IASMA database for Pinot noir ENTAV 115. We named these two...

Wood formation in Angiosperms Inra
Dejardin, A.; Laurans, F.; Arnaud, D.; Breton, C.; Pilate, G.; Leplé, J.C..
La formation du bois est un processus de développement complexe, impliquant cinqétapes majeures : (1) la division des cellules à partir d’un méristème secondaire, appelé le cambium; (2) l’élongation des cellules ; (3) le dépôt d’une paroi secondaire épaisse ; (4) la mort programmée des cellules ; et (5) leur imprégnation par des composés phénoliques conduisant à la formation du bois de coeur. Grâce au développement des techniques de génomique et aux travaux menés sur la caractérisation d’arbres transgéniques, certains mécanismes moléculaires impliqués dans la formation du bois commencent à être mieux connus. Dans cette revue, deux aspects importants pour la qualité du bois seront approfondis : la lignification et le contrôle de l’angle des microfibrilles...
