Abstract

When driving a car with automatic transmission, one hardly notices that extra gears give more power to the car. But in a car with manual transmission, one is constantly aware that even one gear shift helps to reach your goal much more efficiently. For Phytophthora pathogens, a domain characterized by the amino acid motifs RXLR and dEER seems to function as a special gear. In this issue of The Plant Cell, Dou et al. (2008b; pages 1930¿1947) report that an RXLR-dEER domain embodies the complete machinery that the pathogen needs to deliver effectors into host cells. This is in contrast with the bacterial type III secretion system, which requires a multitude of proteins to accomplish this task (see figure panels A and B).
