Analysis of temporal gene expression during flower development. a-j Inflorescences of AP1pro:AP1-GR ap1-1 cal-1 plants a before dexamethasone treatment (0 d time-point) , and b 1 d, c 2 d, d 3 d, e 4 d, f 5 d, g 7 d, h 9 d, i 11 d, and j 13 d after treatment with a solution containing 10 μM dexamethasone. The development of flowers on a given inflorescence was largely synchronous until day 7. For later time-points (h-j), flowers were harvested from the tip of the inflorescences (arrowheads) after phenotypic assessment. k Experimental set-up used for this study. Floral buds were collected from the inflorescences of AP1pro:AP1-GR ap1-1 cal-1 plants at 14 time-points immediately before and after treatment with a dexamethasone (‘DEX’)-containing solution, which induces flower development by activating the AP1-GR fusion protein. Floral buds from the time of initiation until anthesis (corresponding to stage 13) were sampled
