Figure 6
Drought-related levels of selected metabolites showing significant changes in leaves of the hsi2-2 mutant . Each sample consisted of a minimum of 6 plants grown under well-watered (to near field capacity) or drought-stressed (visible wilting) conditions, and 24 h after re-watering to soil saturation following drought stress. Values represent averages of three biological replicates ± standard error. Treatments statistically different by ANOVA (p ≤ 0.05) are marked by asterisks.
