| Outline of Final Research Achievements |
We found that RPS4 and RRS1 function as a dual resistance protein system that prevents infection by three distinct pathogens (Anthracnose; Colletotrichum higginsianum, Bacterial wilt; Ralstonia solanacearum, and Bacterial speck; Pseudomonas syringae pv. tomato strain DC 3000 expressing avrRps4). We demonstrated that a pair of Arabidopsis NB-LRR-type R genes, RPS4Ws and RRS1Ws, function in two Brasscicaseae, but also in two Solanaceae. In this study, we analyzed that whether a pair of neighboring genes, RPS4 and RRS1, function cooperatively as a dual resistance protein system and then this system are tightly regulated. Our finding will contribute to a new strategy for creating pathogen-resistant vegetables and crops by a transgenic approach.
