Figure 3. Media and temperature-dependent ability of P. syringae to elicit HR.

P. syringae DC3000 expressing the effector AvrRpm1 cultivated on three types of solid media (A) or at two different temperatures (B) were vacuum infiltrated into wild-type Col-0 leaf discs (OD₆₀₀ = 0.1). Culture media used in B was Pseudomonas agar F (King’s B medium, Biolife, Milano, Italy). Mean and standard deviation where n = 6 (A) and n = 6 (B) are shown. Experiments were replicated with similar results.
