Arabidopsis plants grown in liquid medium (a), sterilized planting mix (b) or sterilized planting mix supplemented with activated charcoal (30 mg per gram of planting mix) (c) were infected with the indicated P. syringae strains. The appearances of disease symptoms on roots and leaves infected with specific P. syringae strains are described in Supplementary Figs S1 and S2. In all cases, disease symptoms were photographed on the seventh day after inoculation. Experiments were repeated twice, each experiment containing three replicates of 20 plants each. Arrows indicate chlorosis and plant mortality.
