Tolerance to ABA of the double mutants.

aThese values are represented as percentages of root length of plants transferred to non-supplemented media as described in Methods. Each value corresponds to the mean ± SD of the root length of 15 plants of each genotype.bValues shown are the mean ± SD of the percentages of green expanded cotyledons seedlings of two replicates of 50 seeds each scored 10 das. N.D.: not determined.c–eMutant genotypes in a cCol-0,dLer oreLer/Col-0 mixed genetic background, respectively.f,gDifferences were significant fromfCol-0 and Ler or gonly from Col-0, respectively. Values were significantly different from the corresponding wild type at *Pt-test.
