Validation of the Nodules

After a half year we are getting closer to a successful experimental process. By visualizing the fist satisfactorily grown nodules under the microscope!

The grey pictures were taken under the light microscope while the red ones are made with fluorescent light!

In the next two pictures you can see a nodule with a higher magnification. The red dots on the left side of the nodule are the nitrogen fixing bacteria (Sinorhizobium meliloti).
