Plant defense: one post, multiple guards?!

Mol Cell. 2003 Feb;11(2):284-6. doi: 10.1016/s1097-2765(03)00072-8.

Abstract

Arabidopsis RIN4 is a key bacterial virulence target that is guarded by the resistance (R) protein RPM1. Two recent studies suggest that another R protein, RPS2, also guards RIN4. Bacterial avirulence (Avr) effectors AvrB, AvrRpm1, and AvrRpt2 alter this key protein. R proteins RPM1 and RPS2 recognize the altered status and initiate a defense-signaling response. The guard hypothesis is in!
