Change of HR cell death in protease-silenced plant following avirulent bacterial pathogen inoculation.

<p>Protease-silenced plants were infiltrated with avirulent bacterial pathogen <i>P. syringae</i> pv. <i>tomato</i> T1 (OD₆₀₀ = 0.2). The HR cell death symptoms were taken at 1 dpi (A) and 2 dpi (B). The bar graph indicates the numbers of showing enhanced (A) or delayed (B) HR cell death from each protease family (left panel). The right panel shows the representative member from each family representing enhanced (A) and delayed (B) HR cell death. 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>tomato</i> T1 infection. One representative experiment is shown.
