in order to evaluate the effects of biofertilizer on soybean (glycine max l.) seed vigor that produced under water deficit condition and related traits, an experiment was conducted in a factorial layout based of complete randomized block design with four replications at the research greenhouse of aboureihan campus- tehran university, iran. experimental treatments were include biofertilizer (see...

Rhizobial isolates that were obtained from both surface and deep soil samples in the Sahelian and Sudano-Guinean areas of Senegal (West Africa) under Acacia albida trees were compared with representative strains of known rhizobial species and genera. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) of proteins was used to determine the taxonomic positions of these organisms ...

soybean, glycine max (l.) merr is one of the most important oilseed plants in the world and phythophthora root and crown rot is a significant limiting factor for its planting. in the present study the antagonistic effect of 12 trichoderma spp. in vitro and these trichoderma spp. in combination with bradyrhizobium japonicum in vivo on phytophthora sojae and soybean growth were tested. in laborat...

many researchers consider the use of different probes for hybridization assays as suitable for studying the genetic diversity of nitrogen fixing bacteria. in this study for asessing genetic diversity among bradyrhizobium japonicum isolates, two different probes (suca and topa) chosen from the chromosomal genome of bradyrhizobium strain usda 110 were designed, evaluated by dnaman software and im...

some research indicates that n2 fixation in soybean cannot provide adequate nitrogen for proper yield. therefore, the effect of nitrogen and bradyrhizobium japonicum bacteria on some agronomic characteristics and quality of soybean cultivars was examined based on split plot in a randomized complete blocks design with three replications in 2012 at kerman township. treatments including control (w...

Many researchers consider the use of different probes for hybridization assays as suitable for studying the genetic diversity of nitrogen fixing bacteria. In this study for asessing genetic diversity among Bradyrhizobium japonicum isolates, two different probes (sucA and topA) chosen from the chromosomal genome of Bradyrhizobium strain USDA 110 were designed, evaluated by DNAMAN software and im...

Highly diverse Bradyrhizobium strains nodulate genistoid legumes (brooms) in the Canary Islands, Morocco, Spain and the Americas. Phylogenetic analyses of ITS, atpD, glnII and recA sequences revealed that these isolates represent at least four distinct evolutionary lineages within the genus, namely Bradyrhizobium japonicum and three unnamed genospecies. DNA-DNA hybridization experiments confirm...
