CAT3 accumulation levels in Col-0 or CMV-Y-infected Col-0 after MG132 treatment. CMV-Y was inoculated 2 days before MG132 treatment. Leaves were treated for 3 days by MG132, and CAT3 was detected by Western blots using anti-CAT3 antibodies. The band intensity of CAT3 was normalized by that of Rubisco large subunit visualized by Coomassie brilliant blue (CBB) staining. The CAT3 level in nontreated control leaves (Control) was set to 1.0. Data are means of 3–4 independent replicates with SD. Differences in means were evaluated by t test; one asterisk and two asterisk indicate significance at the 0.05 and 0.01 levels, respectively. A representative image of a Western blot is shown in Supplementary Fig. 4
