We found that mkp1-1 plants showed higher expression levels of PDF1-2 and PAD3 than Col-0 plants upon infection with the three pathogens, and that the expression of PR1 and CYP81F2 genes was also higher in mkp1-1 than in Col-0 upon Pto and Hpa infection (Figure 7). Here, PADI3 is linked to infection.
