FIG. 1.

abo1-1 mutant plants are resistant to drought stress. Reduced wilting was observed for abo1 mutant plants during water stress treatment. Wild-type (WT) and abo1-1 plants were grown with sufficient water for (A) 3 or (B) 2 weeks, and then water was withheld for 11 days. (C) Water loss in detached leaves from 3-week-old plants placed in a room (40% rH) for 14 h. (D) Comparison of rates of water loss from detached leaves of the wild-type and abo1-1 plants. Water loss is expressed as the proportion of initial fresh weight. Values are means ± SE from 15 leaves for each of three independent experiments.
