(A) Kinetics of bacterial growth in tomato plants transformed with 35S:Bs2. Plants were vacuum-infiltrated with Xcv (with or without avrBs2) at a concentration of 1 × 105 colony-forming units (cfu)/ml. Bacterial concentrations in plant leaves were assayed after 0, 3, 6, and 8 days. Data points represent the mean of three replicate experiments plus or minus SE. (B) Disease symptoms on tomato (VF36) transformed with or without 35S:Bs2 2 days postinoculation of Xcv(avrBs2) at 1 × 106 cfu/ml.
