Mediator Kinase Module Components MED12 and MED13 Mediate Defense Responses.

(A) Growth phenotypes of 4-week-old wild-type, cdk8, med12, and med13 mutant plants.

(B) B. cinerea disease symptoms and disease lesion sizes in the wild type and Mediator kinase module mutants.

(C) A. brassicicola disease symptoms and disease lesion sizes in the wild type and Mediator kinase module mutants.

(D) Enhanced cuticle permeability of the wild type and Mediator kinase module mutants revealed by toluidine blue staining.

(E) Relative expression of defense and cuticular wax genes in the wild type and Mediator kinase module mutants.

The disease assays in (B) and (C) were conducted as described in Figure 1. The lesion sizes are mean values ± se from at least 20 disease lesions, and the data were analyzed with Student’s t test (*P < 0.05, **P < 0.01).
