The shikimate pathway is affected by the circadian clock and phyB signaling.Twelve-day-old agar plate grown plants under LI = 22 ± 2 μmol m⁻² sec⁻¹ were used in these experiments. Values are means ± standard error (SE) of three replicates and times start from 0 h as day light begins. Shaded areas indicate the night cycle. Data are expressed as log2 and asterisks indicate significant differences.(a) Transcript accumulation of shikimate pathway components under regular day-night regime. Ratio of relative transcript numbers at 1 h/8 h and 16 h/8 h of both genotypes are written next to the corresponding gene. (b) Transcript abundance of circadian clock and phyB downstream signaling elements. Ratios of transcript levels of gre1/wt are written above the bars of the corresponding genes. (c) Transcript level of shikimate pathway and circadian clock components under continuous light condition with the ratios of 30 ZT/24 ZT plotted next to the corresponding genes.
