Fig. 4

Patterns of the FHY3/FAR1 diurnal expression. Quantitative gene expression data from plants grown in short days (0–9 h light period) in а climatic chamber. Gray shadowing indicates the dark period (9–24 h). The graphs compare the expression between the photoperiod insensitive NILs “Ppd-m” (green), “Ppd-w” (purple). Values are expressed as the relative levels normalized against 18S ribosomal RNA. Error bars indicate the SE of the means. Asterisks indicate significant (P < 0.05) differences in a one-way ANOVA with a post hoc Tukey test comparing the “Ppd-m” and “Ppd-w” in each time point
