Plant immunity and film Noir: what gumshoe detectives can teach us about plant-pathogen interactions.
Plant cells practice constant vigilance using resistance (R) proteins to monitor pathogenic processes. Three papers published recently in Cell and one in Science provide support for a model in which plant cells set up surveillance of signal transduction pathways, preparing to destroy the cell if any untoward fiddling with cellular physiology is detected. The demonstration of three separate examples of such a system suggests that it is broadly used and should provoke a reexamination of microbial pathogenesis in animal cells to look for similar mechanisms.
