Changes in NPQ and its qESV and qI components in the indicated genotypes during a 5 d course of varying light. (A) Five day light regime; (B) NPQ; (C) qESV; (D) qI. Measurements were taken every 60 min on Days 1 and 4, and at the end of each light interval on all other days. The color scale at the bottom depicts the log-fold increase (red) or decrease (blue) in values in the mutants normalized against values in the corresponding parental lines (WT; black) at each time point. The qI values in both Ler and arc11 were almost zero (white) towards the end of Day 4 (raw data in Supplementary Fig. S9). Each data point represents the mean of measurements from 6–10 plants. Raw data and statistical analysis are shown in Supplementary Figs S8–S11.
