Figure 4.

In R, phyB1 mutants show significantly faster gravitropism than wild type or phyB2 mutants. The average degree to which 5‐day‐old dark‐grown seedlings bent toward the negative gravity vector (i.e., upwards) after gravistimulation over 24 hr is shown. Seedlings were either gravistimulated in the dark (left), or with 135 µmol photons m⁻² s⁻¹ of R. Error bars represent standard error. The dark and R plots each contain data from three biological replicates. N = 20 per genotype per time point per biological replicate. A three‐way ANOVA with time, genotype, and light condition was performed followed by Tukey's post hoc test in R. Shared letters represent no statistically significant difference
