Figure 6From: Loss of the N-terminal domain of chlorophyllide aoxygenase induces photodamage during greening of Arabidopsis seedlingsMolar ratio of the chlorophyll a and b contents in the seedlings during greening. The etiolated seedlings were first grown for 4 days under dark conditions and were subsequently exposed to low light. The compositions of chlorophyll a and b were calculated from chromatographic peak profiles at 650 nm with HPLC analysis. The error bars represent standard deviations (n = 4).Back to article page
