Change of disease symptom development in protease-silenced plant following virulent bacterial pathogen inoculation.

<p>Protease-silenced plants were infiltrated with virulent bacterial pathogen <i>P. syringae</i> pv. <i>tabaci</i> (OD₆₀₀ = 0.005). The disease symptoms induced by the pathogen were taken at 3 dpi. The bar graph indicates the numbers of showing delayed disease development from each protease family (left panel). The right panel shows the representative member from each family which showed delayed symptom. For every protease gene, 6 sections per 1 leaf were infected with the pathogen and total 2 leaves were used for 1 plant. Total 4 plants were infiltrated at each experiment. Similar results were obtained from at least three independent experiments. Red dotted line indicates the site of <i>P. syringae</i> pv. <i>tabaci</i> infection. One representative experiment is shown.
