Figure 4. Effects of day length on hypocotyl length in 9-day-old wild-type and Arabidopsis rav mutants under LDs and SDs.
A, Histograms of the mean (n = 20) for seedlings grown on medium. The seedlings were scored 9 d after sowing. Scale bar = 10 mm. *differences in comparison to the non-transgenic lines at 0.01<P<0.05, **Significant differences in comparison to the non-transgenic lines at P<0.01 (Student’s t test). B, Phenotype of 9-day-old WT seedlings and Arabidopsis rav mutants on MS medium under LDs and SDs. C, Representative seedlings are shown.
