Enhanced disease susceptibility of the cycd3;1,2,3 mutant was rescued by BTH treatment. A, Bacterial growth assay with PmaDG3. Plants were sprayed with 300 μm BTH or water for 24 h, and the fifth to seventh leaves of the treated plants were infiltrated with the virulent strain PmaDG3 (105 bacteria/mL). Leaf discs were taken 3 d post infection for the measurement of bacterial growth. Statistical analysis was performed with Student’s t test (StatView 5.0.1). The asterisk indicates significant difference between Col-0 and cycd3;1,2,3 with water treatment (n = 6; P < 0.05). B, Disease symptoms. Pictures of the infected leaves were taken at 4 d post infection. C, Bacterial growth assay with PmaDG6 or PmaDG34 infection. These experiments were repeated twice with similar results.
