Instrument: JEOL 1010 TEM Microscopist: Louisa Howard. Transmission electron microscope image of a cross section through a soybean(Glycine max.Essex) root nodule. The bacteria, Bradyrhyzobium japonicum, infects the roots and establishes a nitrogen fixing symbiosis. This image shows a cell and an infection thread. In this image, you can also see a cell in process of dividing.

 02_RootNodule80938_50KX.jpg |
Instrument: JEOL 1010 TEM Microscopist: Louisa Howard. Transmission electron microscope image of a cross section through a soybean(Glycine max.Essex) root nodule. The bacteria, Bradyrhyzobium japonicum, infects the roots and establishes a nitrogen fixing symbiosis. This high magnification image shows part of a cell with single bacteriods within their symbiosomes. In this image, you can also see endoplasmic reticulum and the cell wall.
