FIGURE 5.
Hypothetical scenario of bacterial community ecology in development of huanglongbing. (A) Bacterial composition of CLas-associated microbiota plays a key role in nutritionally and environmentally supporting colonization of the host by CLas. Interplay between CLas and phloem-inhabiting bacteria constructs a community that is likely to contribute to development of huanglongbing. (B) Antibiotic stress triggers structural changes in the CLas-associated microbiota. For example, oxytetracycline does not inhibit CLas but eradicates a sub-community that supports CLas. Changes in the community structure make the community less habitable for CLas.
