Intracellular production of ROS in Arabidopsis mesophyll cells. Plant cells were incubated for 24 h without SWCNTs (negative control) or with 0, 15, 25, 50, 100 μg/ml of SWCNTs and stained with C-400. Fluorescent intensity was monitored by flow cytometry. The intracellular generation of ROS is expressed as the percentage of control. Hydrogen peroxide (H2O2) was used as a positive control. Bars indicate the mean ± SE of two independent experiments.
