Fig. 5. — ahr1 mutant seedling roots display long-term growth resistance in the presence of a water potential gradient generated by sorbitol. Seeds of the wt and ahr1 were sown in a horizontal WSM→NM system with a water potential gradient where the WSM region contained glycerol, NaCl, or sorbitol. Measurements were scored after 11 d of germination. Similar osmolarity (Osmomol/kg) was used in the preparation of the medium with glycerol, sorbitol, or NaCl. Data represent the mean root length of three different experiments (n=24 for each treatment and plant). Error bars represent the SD. Bars with different letters differ significantly after two-way ANOVA with Bonferroni post-tests, p < 0.01.
