Temperature-dependent internode elongation. A, The phyAphyBphyE triple mutant, grown at 16°C (left) and 21°C (right) at photon irradiance, 400 to 700 nm, 100 μmol m⁻² s⁻¹. B, Rosette internode length (millimeters) of 21°C-grown wild type and phyAphyBphyE. Plants were grown in SDs for these experiments; bars represent the se. C, Wild-type seedlings grown in the dark at 16°C and 26°C. Fresh and electron microgram images were taken of seedlings grown on 3% (w/v) Suc for 3 weeks.
