摘要：

Bacterial wilt phytopathogen Ralstonia solanacearum is a serious soil-borne disease that attacks several economically important plants worldwide, including Brassicaceae. Previous studies indicate that recognition of avirulence (Avr)-effector PopP2 by resistance (R) protein, RR S1-R, and physical interaction between RR S1-R and PopP2 in the nucleus are required for resistance. Of late, we showed that a pair of Arabidopsis thaliana TIR - NLR proteins, RR S1 and RPS4, function together in disease resistance against multiple pathogen isolates. Here, we report that dual R proteins, RR S1 and RPS4, from A. thaliana accession Wassilewskija confer resistance to bacterial wilt in transgenic Brassica crops. For practical applications, this finding may provide a new strategy for developing disease resistant plants that express R genes from other plants.
