The cml46 cml47 and cbp60a cml46 cml47 mutants have elevated SA accumulation. Leaves of Arabidopsis wild-type Col-0, cbp60a, cml46 cml47, and cbp60a cml46 cml47 (triple) were collected for the determination of total SA (A) and free SA (B) from untreated plants or 24 h after infiltration with water, 1 μm flg22, or Pma ES4326 suspension at OD₆₀₀ = 0.002. Data from four independent experiments, each containing two biological replicates, were combined using a mixed-effect linear model. Error bars represent se. Different letters indicate significant differences between means (q < 0.05). n.d., Not detected.
