In Planta Bacterial Growth in Arabidopsis for 50 Days in NahG Versus Col-0.
(A) Col-0 and NahG plants were inoculated with 106 cfu/mL virulent Pst at ∼1-week intervals from 22 to 50 dag. In planta bacterial growth was monitored 3 dai and is presented as the mean of five samples ±sd. A significant difference (Student's t test, P < 0.00003) was observed between in planta Pst growth in young Col-0 plants (22 dag) compared with mature Col-0 plants (43 and 50 dag). This experiment was repeated at least three additional times with similar results.
(B) Mature (43 dag) Col-0 and NahG leaves inoculated with 106 cfu/mL virulent Pst and photographed 3 dai.
