Transmission electron microscope image of a cross section though a soybean(Glycine max.Essex) root nodule. The bacteria, Bradyrhyzobium japonicum, infects the roots and establishes a nitrogen fixing symbiosis. Image shows a cell with single and multiple bacteriods within their symbiosomes. In this image you can also see endoplasmic reticulum, dictysomes and the cell wall. For more information, see the articles:"Bacterium release into host cells of nitrogen-fixing soybean nodules", Roth, E. and G. Stacey, E.J.C.B. Vol. 49 pp.13-23 1989. and "Phenotypic charaterization of the nolA gene of Bradyrhyzobium japonicum", Garcia, M. etal, MPMI Vol.9 #7 pp.625-635 1996.
