Subcellular localization of SA-induced ROS production. A. ROS production and localization in WT cells treated or not treated with SA were detected by double-staining with DCFH-DA and MitoTracker Red CMXRos. B. Levels of mitochondrial ROS in the WT strains treated or not treated with SA. The values are the means ± SDs of three independent experiments, and asterisks indicate significant differences compared with untreated strains (Student's t-test: **P < 0.01).
