Receptor protein kinases--pattern recognition receptors in plant immunity

Trends Plant Sci. 2006 Nov;11(11):519-22. doi: 10.1016/j.tplants.2006.09.005. Epub 2006 Oct 9.


Plant innate immunity is activated either upon perception of pathogen-associated molecular patterns (PAMPs) by pattern recognition receptors (PRRs) or upon resistance (R) protein-mediated recognition of pathogen race-specific effector molecules. Although many plant R proteins have been identified, there is only limited knowledge about plant PRRs. Recently, Cyril Zipfel et al. identified a second Arabidopsis leucine-rich repeat receptor protein kinase implicated in PAMP perception, which suggests that several members of this large protein family function as pattern recognition receptors.
