Gain of At MYBR1 function results in reduced drought tolerance. (A) Reduced drought tolerance in the OxMYBR1 (35S_pro:MYBR1) plants -- lines 31–3 and 42–6. PEG at 10% and 15% concentrations was applied to 35 d old plants of OxMYBR1, mybr1, mybr2 and mybr1xmybr2 and WT (Col-0). Eight plants were used for each treatment. Pictures were taken 5 d after PEG treatment. (B) Detached whole rosette leaf water-loss from 20 d old plants. Transpirational water loss and standard error was calculated at each time point (bar; n = 6). The P-value of two factor ANOVA is 4.7E-18. (C) Rate of chlorophyll leakage from detached whole rosette leaf; standard error (bar; n = 6).
