Publication Inra prise en compte dans l'analyse bibliométrique des publications scientifiques mondiales sur les Fruits, les Légumes et la Pomme de terre. Période 2000-2012. http://prodinra.inra.fr/record/256699; International audience; The symbiotic relationships between legumes and their nitrogen (N-2)-fixing bacterial partners (rhizobia) vary in effectiveness to promote plant growth according to both bacterial and legume genotype. To assess the selective effect of host plant on its microsymbionts, the influence of the pea (Pisum sativum) genotype on the relative nodulation success of Rhizobium leguminosarum biovar viciae (Rlv) genotypes from the soil populations during plant development h…

Importance de la variabilité génétique bactérienne sur le fonctionnement de la symbiose Rhizobium leguminosarum biovar viciae avec le pois (Pisum sat…

2008

Les irrégularités de rendement et de teneur en protéine des graines que présente la culture du pois sont, en partie, liées à des problèmes de nutrition azotée. En tant que légumineuse, la nutrition azotée du pois repose à la fois sur la fixation symbiotique de l’azote atmosphérique et sur l’absorption racinaire des nitrates du sol. Notre principal objectif a été de déterminer si le partenaire bactérien, Rhizobium leguminosarum biovar viciae (Rlv), peut être un facteur limitant de la nutrition azotée et du rendement du pois. La variabilité génétique des Rlv et les facteurs influençant la structure des populations de Rlv à l'état libre et symbiotiques ont été étudiés. La signification de la d…

Rhizobium leguminosarum biovar viciae genotypes interact with pea plants in developmental responses of nodules roots and shoots

2007

International audience; The variability of the developmental responses of two contrasting cultivars of pea (Pisum sativum) was studied in relation to the genetic diversity of their nitrogen-fixing symbiont Rhizobium leguminosarum bv. viciae. A sample of 42 strains of pea rhizobia was chosen to represent 17 genotypes predominating in indigenous rhizobial populations, the genotypes being defined by the combination of haplotypes characterized with rDNA intergenic spacer and nodD gene regions as markers. We found contrasting effects of the bacterial genotype, especially the nod gene type, on the development of nodules, roots and shoots. A bacterial nod gene type was identified that induced very…
