Figure 3.

Relative expression of dehydrin genes in the leaves of wild-type (Col-0), the constitutive ethylene response mutant (ctr1-1) and the ethylene-insensitive double mutant (ein3eil1) grown on ¹/₂ MS medium −/+ 75 mM sorbitol. The plots represent data from three independent experiments, depicting the median (horizontal line in each box), the lowest and the highest values (whiskers endpoints). The red line indicates the basal expression level of each gene measured in control samples of the same genotype. Different letters indicate statistically significant differences in gene expression among the three genotypes (p < 0.05, one-way ANOVA).
