SUMMARY
Bacterial and eukaryotic plant pathogens deliver effector pro-
teins into plant cells to promote pathogenesis. Bacterial patho-
gens containing type III protein secretion systems are known to
inject many of these effectors into plant cells. More recently,
oomycete pathogens have been shown to possess a large family
of effectors containing the RXLR motif, and many effectors are
also being discovered in fungal pathogens. Although effector
activities are largely unknown, at least a subset suppress plant
immunity. A plethora of new plant pathogen genomes that will
soon be available thanks to next-generation sequencing tech-
nologies will allow the identification of many more effectors.This
article summarizes the key approaches used to identify plant
pathogen effectors, many of which will continue to be useful for
future effector discovery. Thus, it can be viewed as a `roadmap'
for effector and effector target identification. Because effectors
