Fig 6. CEP1 contributes to powdery mildew induced leaf lesions on cpr5-2.

(A) Representative leaf lesion on cpr5-2 single mutant plants. (B) Comparison of the necrotic leaf lesion area per colony on cpr5-2 single and on cep1 cpr5-2 double mutant plants. Columns show the area of a necrotic leaf lesion per E. cruciferarum colony (five spores/mm²) five days post inoculation (dpi) measured by fluorescence intensity. The areas showing fluorescence above a certain threshold intensity were measured. Data present the mean of 65 lesions on 19 leaves on cpr5 mutant plants and on cep1 cpr5-2 mutant plants, respectively. Error bars are standard deviations. Differences between cpr5 single and cep1 cpr5-2 double mutants are highly significant after two sided Student’s t-test (p < 0.001, ***). (C) Representative leaf lesion on cep1 cpr5-2 double mutant plants.
