Figure 6.
Senescence phenotype of the why1-1wrky53 and oeWHY1wrky53 double mutants. A and B, Fv/Fm (A) and chlorophyll content (B) of leaf 7 in 9-week-old plants. Means and se of five independent measurements are shown. Different letters indicate significant differences at P ≤ 0.05 based on Student’s t test. C, Senescent leaf fraction from 12 plants at 10 weeks old. Means and se from two independent experiments with six plants each are indicated. D, Leaf phenotypes of 10-week-old plants. Numbers above the images indicate leaf age, with 1 being the oldest. WT, Wild type.
