Fig. 2: ROS content and microscopy observations of drought-stressed receivers.
From: Amplification of early drought responses caused by volatile cues emitted from neighboring tea plants
A Accumulation of H2O2 and O2− as revealed by histochemical staining with DAB or NBT, respectively. B, C Quantitative measurements of O2− (indicated by anti-O2− activity, which is negatively proportional to the O2− level) and H2O2. D Microscopy observations of cross-sections of paraffin-embedded leaves of drought-stressed receivers from T1–T3 and controls (CK); lignin is dyed red by safranin, and cellulose is dyed blue by fast green. The left side shows the main vein of the leaf; the right side shows the thickness of the leaf blade. E Measured leaf thickness. The data were presented as the means ± SDs of at least three measurements. The asterisks indicate significant differences relative to the controls (Tukey’s HSD: *P < 0.05; **P < 0.01)
