The term microbiome was first used in 1988 and defined as "A convenient ecological framework in which to examine biocontrol systems is that of the microbiome. This may be defined as a characteristic microbial community occupying a reasonably well defined habitat which has distinct physico-chemical properties. The term thus not only refers to the microorganisms involved but also encompasses their theatres of activity. In relation to fungal diseases of crops and their control, major microbiomes are the phylloplane, spermosphere, rhizosphere and rhizo- plane, and numerous kinds of plant residues persisting on or in the soil. Mention should also be made of the wood of standing or felled trees as microbiomes where biocontrol of forest diseases using fungi has been achieved. However, in most cases competitive interactions other than mycoparasitism seem to be of greater importance.*

Use CLPP to compare the phyllosphere and rhizosphere to the (soil and/or water) environment of one of the following plants.

  1. Spartina foliosa
  2. Delairea odorata
  3. Baccharis pilularis
  4. Baccharis douglasii
  5. Eucalyptus globulus
