Plant targets for Pseudomonas syringae type III effectors:
virulence targets or guarded decoys?
Anna Block and James R Alfano
The phytopathogenic bacterium Pseudomonas syringae can
suppress both pathogen-associated molecular pattern
(PAMP)-triggered immunity (PTI) and effector-triggered
immunity (ETI) by the injection of type III effector (T3E) proteins
into host cells. T3Es achieve immune suppression using a
variety of strategies including interference with immune
receptor signaling, blocking RNA pathways and vesicle
trafficking, and altering organelle function. T3Es can be
recognized indirectly by resistance proteins monitoring
specific T3E targets resulting in ETI. It is presently unclear
whether the monitored targets represent bona fide virulence
targets or guarded decoys. Extensive overlap between PTI
and ETI signaling suggests that T3Es may suppress both
pathways through common targets and by possessing
multiple activities.
