Document Summary
There are three different types of plant-microbe interactions: Commensalisms: this is where the microbe benefits from the plant and the plant is not harmed. Mutualism: both the microbe and the plant benefit. Communication between the plant and microbe are crucial for any relationship. They both produce chemical signals and monitor the physiology of the other so they can react accordingly. Microbes exist in various locations in relation to plants: The phyllosphere is the location of the stems/leaves of the plant. Below ground plant surfaces: rhizosphere and rhizoplane. The rhizosphere is the region surrounding the plant roots while the rhizoplane is the location at the plant root surface. Epiphytes live next to or on the rhizoplane while endophytes live within the rhizosphere. The phyllosphere is the aerial portion of plants that contains stems and leaves, basically the part that is exposed to the outer environment. The microbes that live here are constantly exposed to rapid changes in:
