Rosette leaf production rate in 16°C SDs. A,
Rosette leaf number was counted at time intervals (days) until
flowering time in plants grown at 16°C in SDs (photon irradiance,
400–700 nm, 180 μmol m−2
s−1). Bars represent the se. WT,
Laer wild type; B−, phyB;
D−, phyD; and
E−, phyE null mutations. B,
Laer WT, and phyBphyD, phyBphyDphyE
mutants grown in SDs for 46 d.
