Microscopy-Based Evaluation of Bacterial Attachment to Plant Root Surfaces

Key Points

To evaluate how bacteria attach to plant root surfaces using microscopy techniques.
Used phase-contrast microscopy to observe bacterial adhesion.
Mounted root samples from seedlings that were incubated with bacteria.
Washed samples to remove loosely attached bacteria before observation.
Counted the number of bacteria attached to root hairs under the microscope.
Bacterial attachment to root hairs was successfully quantified.
Phase-contrast microscopy provided clear visualization of bacteria on roots.

Abstract

Source: Matthysse, A. G. Adherence of Bacteria to Plant Surfaces Measured in the Laboratory. J. Vis. Exp. (2018).This video demonstrates the evaluation of bacterial attachment to plant roots using phase-contrast microscopy. Root samples from seedlings incubated with bacteria are first mounted to check for free bacteria. The samples are then washed to remove loosely attached bacteria and remounted using a suitable coverslip to prevent damage. Finally, the number of bacteria attached to the root hairs is counted under the microscope.
