Figure 6.
Stimulation of secondary cell wall deposition by UV-B. A, Percentage of trichomes with the OR is increased by the UV and decreased by the MeJA treatment in wild-type (WT) trichomes. B, Relative cell wall thickness of the cell wall in the trichome stalk above the OR. Different letters above bars mean significant differences using the χ2 test in A (P < 0.01) and ANOVA with the HSD Tukey post hoc test (P < 0.05) in B. Error bars represent se. The measurements were made in three biological replicas on more than 20 plants and more than 100 trichomes per treatment and genotype.
