Are there plant antimicrobial compounds?

Plants make nice environments for bacteria to live. Bacteria that live on leaf surfaces (the phyllosphere) or in the root zone (the rhizosphere) often receive nutrients that are exuded by the plant. Some of these bacteria can cause infections and harm the plant.
We are hypothesizing that some plants may produce natural compounds that have antibiofilm activity. We are currently developing a procedure for identifying these kinds of plants.
