Plant pathogens use two different strategies to gain an edge over the host defenses: suppression and subversion. The suppression strategy is relatively well studied and it is exemplified by bacterial avirulence proteins, which suppress the host basal defense and by viral suppressors, which inactivate the host RNA silencing defense. Unlike defense suppression, the defense subversion strategy is virtually unexplored, although "enslaving", rather than "killing", a cellular pathway would appear to represent a more complex feat for a pathogen. The process of genetic transformation of plants by Agrobacterium includes mechanisms for host defense subversion, which will be described in this talk.
