The effect of transferring Arabidopsis at daily intervals (expressed as days from 50% germination) from LD to SD on flowering time in (a) Col-0, (b) tem1 and (c) RNAi-tem1/2. JVP: juvenile phase, AVP: adult vegetative phase, RP: reproductive phase, SD: short day, LD: long day. The orange dotted lines delimit the three different phases. Vertical error bars denote the standard error of the mean of the number of leaves. Horizontal error bars denote the standard error of the mean of the estimated phase length. Logistic curve (grey curve), maximum slope (black line), lag time lines (blue horizontal lines). JVP: Col-0 vs. tem1 p = 0.0104; Col-0 vs. RNAi-tem1/2 p = 0.0007; tem1 vs. RNAi- tem1/2 p = 0.0029. AVP: Col-0 vs. tem1 p = 0.042; Col-0 vs. RNAi- tem1/2 p = 0.0021; tem1 vs. RNAi- tem1/2 p = 0.0072. Data were analysed by Tukey's multiple comparisons test after two-way ANOVA (p < 0.001).
