Figure 7. A. thaliana plants exposed to drought stress.

Plants overexpressing mSAL1 (msal1) and SAL1 (sal1) and wild-type plants (WT) were grown under control conditions (6 weeks old), and under moderate (6 weeks old) and severe (7 weeks old) drought (as indicated). (A) Representative plants, watered normally (control) or under moderate drought (two weeks without watering) or severe drought (three weeks without watering). (B) Differences in plant weight; the weights of revitalized plants (i.e. after moderate/severe drought) were deduced from weight of plants which were grown in normal conditions. Positive difference values indicate a successful revitalization. Dry weight is shown on the top plots and fw/dw ratio is plotted in the bottom for moderate and severe drought, respectively.
