Bacterial growth in plants infiltrated with Pseudomonas syringae pv. maculicola strain DG3 (PmaDG3).
(A) Time scheme used in this report. The white box indicates the light period and black boxes indicate dark periods. (B) ZT1 infection. (C) ZT13 infection. In 12 hr L/12 hr D (LD), 25-day-old plants were grown and infected by infiltration with PmaDG3 at 1×105 colony forming unit (CFU)/ml. Bacterial growth was assessed at 3 dpi. Data represent the average of bacterial numbers in six samples ± standard error. Log transformed bacterial growth was used in statistical analysis (Student's t-test). Letters indicate significant difference among the samples (P<0.05). These experiments were repeated three times with similar results.
