Fig. 3From: Effects of volatile organic compound ether on cell responses and gene expressions in Arabidopsis DAB assay for H2O2 production induced by ether on Arabidopsis leaves. Arabidopsis plants were fumigated with 500 μL/L of ether for various time intervals (a). Panel (b) is the close-up pictures of the DAB staining. Three replicates for each treatment were performed, and representative leaves were presented. W wounding; Un untreated plants. Scale bars = 300 μmBack to article page
