An intricately structured soil bacterium, less than a micron in size, makes its home on the root surface of an Arabidopsis plant. The image is from a related DOE project at the Environmental Molecular Sciences Laboratory, a U.S. Department of Energy Office of Science national scientific user facility located at Pacific Northwest National Laboratory, to understand how carbon within the root zone impacts the diversity and function of the rhizosphere microbial community.
