Figure 6. Influence of bacterial titer on the outcome of HR.

Leaf discs from wild-type Col-0 (A) or rpm1.3 (B) Arabidopsis were simultaneously vacuum infiltrated with five concentrations (OD₆₀₀ = 0.001–0.1) of P. syringae DC3000 expressing the effector AvrRpm1. Mean and standard deviation where n = 6 are shown. At indicated times, discs were stained with trypan blue for visualization of induced cell death (C). All images are shown at same scale. Scale bar indicates 500 µm.
