Fig. 7From: Plasma membrane aquaporins of the PIP1 and PIP2 subfamilies facilitate hydrogen peroxide diffusion into plant rootsRelative root length of PIP knockout mutants under control and H2O2 treatments. Root length under control conditions has been set to 100% (indicated by the dashed line). Absolute values for root length can be found in Fig. 6 and Supplementary Table S2 in Additional file 2. Asterisks inside the columns indicate statistically significant treatment effects. Given are means ± SE for n = 9 – 18 plantsBack to article page
