Table III. Drought stress phenotypes.
Data are presented as averages ± se. Days, Number of days under treatment conditions; N, replicates; E, transpiration. Asterisks indicate significance when comparing the wild type with the mutant using pairwise Student’s t test: *, P < 0.05; **, P < 0.01; and ***, P < 0.001.
