Total and cyanide-resistant, SHAM-sensitive O2-uptake rates of wild-type Arabidopsis leaves infiltrated with avirulent or virulent strains of Pst, expressed in units of fresh mass (FM). A, Leaves infiltrated with suspensions containing 107 CFU of the pathogens per mL. Circles, Control; triangles, avirulent pathogen; and squares, virulent pathogen. Open symbols indicate total O2-uptake of the leaves; closed symbols indicate cyanide-resistant, SHAM-sensitive O2 uptake. B, Systemic, noninfiltrated leaves of mock plants infiltrated on lower leaves 3 d earlier. Results are mean values ± se; n = 4.
