Alternaria brassicicola‐infected Col‐0, rbohd, erecta SALK_04410 and erecta SALK_066455C mutant Arabidopsis plants. Fungal symptoms were photographed at 7 days after inoculation. T‐DNA insertion lines with mutations in the genomic sequence of RbohD (At5g47910) and ERECTA (At2g26330) genes were used. Necrotic fungal symptoms are more intense in the two erecta mutants, as in the rbohd mutant, in comparison with the Col‐0 wild‐type. Five‐ to six‐week‐old Arabidopsis plants (whole rosettes) were spray inoculated with A. brassicicola conidial suspension at a concentration of 5 × 105 conidia/mL distilled water.
