Loss of PIF function delays degreening of detached dark-held inflorescences. Inflorescences were held in the dark for 3 d. Data are means of five to six inflorescences. Significance was determined for comparison with values in ecotype Columbia (Col-0). Error bars are 95% confidence intervals for the mean. *P < 0.05, ***P < 0.001. For a visual representation of the delay, see Supplemental Figure S7. D0, Day 0.
