Theimpairment of bak1-5 in bacterial resistance was furthersupported by the increased disease symptoms observed after spray-infection withPto DC3000 COR− (Figure S4).In addition, Col-0, bak1-4 and bak1-4 plantsexpressing BAK1 displayed no significant disease symptoms after spray-infectionwith Pto DC3000 COR-, whereasbak1-5 or bak1-4 plants expressing BAK1-5clearly develop chlorotic lesions associated with disease (FigureS4). This evidence concerns the gene BAK1 and infection.
