Genetic interaction of phyA and phyB in the shade-induced hypocotyl elongation. A) Cartoon showing the design of the experiment. Seedlings were germinated and grown in W (R:FR > 1.5) for 2 d, and then they either maintained in W or transferred to simulated shade (W + FR, R:FR, 0.02) for 5 more days. On Day 7, pictures were taken and hypocotyl (HYP) length was measured. B) HYP length of Col-0, phyA-211, phyB-9, and phyA-211 phyB-9 double mutant seedlings after growing in W (HYPW) or W + FR (HYPW + FR). Values are means and error bars are Se of 3 independent replicates. C) Elongation response (HYPW + FR − HYPW) of lines shown in B). Values of HYPW and HYPW + FR (shown in B) were used to calculate HYPW + FR − HYPW. Se was propagated accordingly. In B), different letters denote significant differences (2-way ANOVA with the Tukey test, P < 0.05) among means. In C), asterisks indicate significant differences (based on the 2-way ANOVA) between the mutant and wild-type genotypes in response to simulated shade (**P < 0.01).
