Dual Role of Hydrogen Peroxide in Arabidopsis Guard Cells in Response to Sulfur Dioxide
Figure 2
Effects of antioxidants and calcium antagonists on SO2-induced stomatal closure and H2O2 elevation in Arabidopsis guard cells. Different superscript letters indicate significant differences (). The same letters indicate no significant difference. The green fluorescence (DCFH-DA) of guard cells indicates H2O2 content.
