NaCl-effect on root growth in RAP2.4 KO-lines. Wildtype (Col-0) plants and the RAP2.4 KO-lines were transferred at an age of 2 days on 0 and 100 mM NaCl and grown in randomized patterns vertically for 7 additional days. The root lengths of six plants per line were determined on 5 plates per treatments. The root lengths in the KO-lines were plate-wise normalized to the root length in wildtype plants. Top graph: Root length in RAP2.4-KO lines on 0 mM NaCl relative to the root length in wt plants. Middle graph: Root length in RAP2.4-KO lines on 100 mM NaCl relative to the root length in wt plants. Bottom graph: Effect of 100 mM NaCl-treatment on the root length relative to the root length on 0 mM NaCl. The graphs depict the mean and the standard derivation. The asterisks mark significance of difference from wildtype (two-way ANOVA; p < 0.01)
