Fig. 2From: Plasma membrane aquaporins of the PIP1 and PIP2 subfamilies facilitate hydrogen peroxide diffusion into plant rootsRoot-to-shoot ratio of individual plants at 31 days old. Means ± SE, n = 8 – 10 plants. Square symbols denote control conditions and circles treatment with 1 mM H2O2. Different letters indicate significant differences between the lines under control (upper case) and H2O2 treatment (lower case) conditions. The relative increase/decrease in the ratio due to the treatment is given for each plant line in Table 2Back to article page
