  Effect of different genestein concentrations on nitrogen content and nodulation in annual medics was studied this research was done under controlled environmental condition at the 20/25 oC day/night air temperatures and 5 oC low root zone temperature. Three annual medics species (Medicago polymorpha, Medicago radiate, Medicago rigidula) adapted to cold and temperate zones and 5 genestein leve...

to study the effect of planting dates and genistein application on nitrogen content and nodulation of three annual medic species (medicago polymorpha cv. santiago m. rigidula cv. ragidula, and m. radiata cv. radiata), an experiment was conducted during 2005-2006 in the research farm of faculty of agriculture, shahed university, tehran. the treatments were arranged as split split plot in a rando...

In order to study the effect of planting dates and genistein on nitrogen content and nodulation of three annual Medicago species (Medicago polymorpha cv. Santiago M. rigidula cv. Ragidula, and M. radiata cv. Radiata), an experimental study was conducted during 2004-2005 on the Research Farm of Faculty of Agriculture, Tarbiat Modares University, Tehran (35°43′N and 51°8′E). The factors were arra...

Cultivar Afghanistan peas are resistant to nodulation by many strains of Rhizobium leguminosarum bv. viciae but are nodulated by strain TOM, which carries the host specificity gene nodX. Some strains that lack nodX can inhibit nodulation of cv. Afghanistan by strain TOM. We present evidence that this "competitive nodulation-blocking" (Cnb) phenotype may result from high levels of Nod factors in...

Of nine Bradyrhizobium japonicum serogroup 123 strains examined, 44% were found to be restricted for nodulation by cultivar Hill. Nodulation studies with soybean isoline BARC-2 confirmed that the soybean Rj4 allele restricts nodulation by the same serogroup 123 isolates. Immunological analyses indicated that B. japonicum strains in serogroups 123 and 31 share at least one surface somatic antigen.

Root nodule symbioses (nodulation) and whole genome duplication (WGD, polyploidy) are both important phenomena in the legume family (Leguminosae). Recently, it has been proposed that polyploidy may have played a critical role in the origin or refinement of nodulation. However, while nodulation and polyploidy have been studied independently, there have been no direct studies of mechanisms affect...

Mechanisms inhibiting legume nodulation by low soil pH, although highly prevalent and economically significant, are poorly understood. We addressed this in soybean (Glycine max) using a combination of physiological and genetic approaches. Split-root and grafting studies using an autoregulation-of-nodulation-deficient mutant line, altered in the autoregulation-of-nodulation receptor kinase GmNAR...

The nodulation of Glycine max cv. Lambert and the nodulation-restricting plant introduction (PI) genotype PI 417566 by wild-type Bradyrhizobium japonicum USDA110 is regulated in a population-density-dependent manner. Nodulation on both plant genotypes was suppressed (inhibited) when plants received a high-density inoculum (10(9) cells/ml) of strain USDA110 grown in complex medium, and more nodu...

Seed treatments with Bacillus cereus UW85 increased nodulation of soybeans in three field seasons and in three different sterilized soils in the growth chamber. In the field, 28 and 35 days after planting, UW85-treated plants had 31 to 133% more nodules than untreated plants. From 49 days after planting until seed harvest, there were no significant differences between nodulation of UW85-treated...
