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 or
eLer/Col-0 mixed genetic background, respectively.
f,gDifferences were significant from
fCol-0 and Ler or gonly from Col-0, respectively. Values were significantly different from the corresponding wild type at *P<0.05 or **P<0.01 using Student’s t-test.
