In the infection of plants with Hpa, the reduction of susceptibility to this pathogen in NahG mkp1-1 and aba1-6 mkp1-1 in comparison to NahG and aba1-6 plants (Figure 6C) could just be associated to a slight increased expression of PAD3 in lines harboring mkp1-1 mutations (Figure 7C). Here, HPSE is linked to infection.
