Soybean preference forBradyrhizobium japonicumfor nodulation

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

Discovery and expression analysis of nodulation genes in soybean

Abstract: Soybean develop new root organs that become nitrogen-fixing nodules in response to signals from rhizobacteria and then use complex systemic signalling to control cell proliferation. Recent application of functional genomics resulted in the characterization of genes encoding Leucine rich repeat (LRR) receptor kinases controlling these early nodulation steps. With short and long distanc...

Effect of nodulation on assimilate remobilization in soybean.

The objectives of this work were to determine the effect of nodulation on dry matter, reduced-N, and phosphorus accumulation and partitioning in above-ground vegetative parts and pods of field-grown soybean (Glycine max [L.] Merr. cv Harosoy).From comparison of nodulated and nonnodulated isolines, it was estimated that nodulated plants attained 81 and 71% of total-plant (above ground) N from up...

Misexpression of miR482, miR1512, and miR1515 increases soybean nodulation.

MicroRNAs (miRNAs) are important regulators of plant growth and development. Previously, we identified a group of conserved and novel miRNA families from soybean (Glycine max) roots. Many of these miRNAs are specifically induced during soybean-Bradyrhizobium japonicum interactions. Here, we examined the gene expression levels of six families of novel miRNAs and investigated their functions in n...
