title: R protein activation: another player revealed.
abstract: Resistance proteins play an integral role in plant innate immunity by perceiving pathogens and triggering defense responses. In this issue of Cell Host & Microbe, Kang et al. uncover CRT1, an ATPase essential for resistance to turnip crinkle virus in Arabidopsis mediated by the Resistance (R) protein HRT. CRT1 interacts with an array of R proteins in vivo, suggesting that it plays a role in R protein activation.
