Jordan, R., and Hammond, J. Cohen, J., Salomon,R., and Loebenstein, G. 1988. The main difference between mycoplasma and phytoplasma is that the mycoplasma refers to pleuropneumonia-like organisms (PPLOs), which can be parasitic in humans, animals, and plants whereas the phytoplasma refers to mycoplasma-like organisms (MLOs), which can be parasitic in plant phloem tissue and some insects. Infected plants have yellow, stunted growth, and small malformed flowers.
