Figure 3.
Determination of the LTR in Arabidopsis wild-type Col (WT) and the mutant sco4 in 7-d-old seedlings. The photosynthetic parameters Fs/Fm (A), chlorophyll (Chl) a/b ratio (B), 1 − qP (C), and ΦPSII (D) were determined. Acclimation conditions are given at the bottom. All values are means from six independent measurements ± sd. Values significantly different between the wild type and sco4 are marked with asterisks (Student’s t test for independent samples; P ≤ 0.05). WL, Normal white light.
