Effects of deletion of CreTPT3 over the diurnal cycle. A) Growth of WT and t3ko2 strains on TP medium agar plates for 4 d under either diurnal cycle (DC) (left panel; 12-h light/12-h dark) or continuous light (CL) (right panel) at an intensity of 60 μmol photon m⁻² s⁻¹ (upper panel) or HL (lower panel: 450 μmol photon m⁻² s⁻¹). The dilution series are 3, 1.5, 0.75, and 0.375 μg mL⁻¹ chlorophyll equivalent. B) Photosynthetic electron transport rate (ETR) of cells grown under a diurnal rhythm with the light period at an intensity of 60 μmol photon m⁻² s⁻¹. C) Accumulation of starch during growth under a diurnal rhythm at a light intensity of 60 μmol photon m⁻² s⁻¹.
