A Rapid Regulatory Response Governing Nodulation in Soybean

Nodulation, nutrient accumulation and yield of rainfed soybean in response to indigenous soybean-nodulating Bradyrhizobia in the Himalayan region of Kashmir-Pakistan

The use of efficient and effective nodulating Bradyrhizobia strains considered as anecologically and environmentally sound management strategy for soybean production. A 2-yr(2009 and 2010) field experiment was conducted to evaluate the effects of seven indigenousBradyrhizobium strains, one exotic TAL-102 and three N fertilizer rates, i.e., 25, 50 and 100kg N ha-1 on the productivity and N2 fixa...

Compensation Against Ineffective Nodulation in Soybean

Two cultivars of soybean [Glycine max (L.) Merr.] were inoculated with nine ratios of ineffective (SM-5) and effective (CC709) strains of Rhizobium japonicum. Plants were grown in the greenhouse and harvested after 33 days. Nitrogenase activity, total shoot N, nodule number, nodule mass, and the proportions of nodules formed by each strain were determined. Nodules were identified serologically ...

Autoregulation of Nodulation in Soybean Plants

A Novel Sucrose-Regulatory MADS-Box Transcription Factor GmNMHC5 Promotes Root Development and Nodulation in Soybean (Glycine max [L.] Merr.)

The MADS-box protein family includes many transcription factors that have a conserved DNA-binding MADS-box domain. The proteins in this family were originally recognized to play prominent roles in floral development. Recent findings, especially with regard to the regulatory roles of the AGL17 subfamily in root development, have greatly broadened their known functions. In this study, a gene from...

GS52 ecto-apyrase plays a critical role during soybean nodulation.

Apyrases are non-energy-coupled nucleotide phosphohydrolases that hydrolyze nucleoside triphosphates and nucleoside diphosphates to nucleoside monophosphates and orthophosphates. GS52, a soybean (Glycine soja) ecto-apyrase, was previously shown to be induced very early in response to inoculation with the symbiotic bacterium Bradyrhizobium japonicum. Overexpression of the GS52 ecto-apyrase in Lo...
