(A–E) Relative SIG5 transcript levels in 10 day dark adapted old photoreceptor mutants, their background accessions and N9313 × cry1cry2 in response to blue (BL), red (RL) and far-red light (FRL) after 24 h exposure to 100–120 µmol·photons·m⁻²·s⁻¹ monochromatic light. The transcript levels were determined by qRT-PCR relative to ACT2 transcript level. The transcript level of dark adapted seedlings was set to 1.0. (F + G) GFP fluorescence in N9313 and N9313 crossed with photoreceptor mutants. Relative GFP fluorescence of N9313 was set as 100%. Results are mean values of 3–8 measurements (±SEM). * indicates significant differences from the respective control line (Student’s t-test, p < 0.01).
