Abstract

Resistance to pathogens mediated by plant resistance (R) proteins requires different signaling transduction components and pathways. Our previous studies revealed that a potyvirus resistance gene in pepper, Pvr9, confers a hypersensitive response (HR) to pepper mottle virus in Nicotiana benthamiana. Our results show that the Pvr9-mediated HR against pepper mottle virus infection requires HSP90, SGT1, NDR1, but not EDS1. These results suggest that the Pvr9-mediated HR is possibly related to the SA pathway but not the ET, JA, ROS or NO pathways.

Keywords: Hypersensitive response; Pvr9; Signal transduction; VIGS.
