Figure 4.
bbx30 and bbx31 are hypersensitive to light. Hypocotyl length and phenotype of 4-d-old Col, bbx30, bbx31, and bbx30 bbx31 mutant seedlings W (17.5 μmol/m2/s; A and B), B (3.88 μmol/m2/s; C and D), R (75.1 μmol/m2/s; E and F), and FR (2.05 μmol/m2/s; G and H) light conditions. Hypocotyl length is expressed in mm. Data are means ± se; n ≥ 20. Letters above the bars indicate significant differences (P < 0.05), as determined by one-way ANOVA with Tukey’s post-hoc analysis. The experiments were performed three times with similar results. The graphs depict the results of one of three experiments.
