Figure 2. Photoautotrophically grown Δslr1768 cells under low and high light.

Δslr1768 cells grown under high light (130 µmol m⁻² s⁻¹) show a cessation in active growth. Graph shows growth of wild-type and Δslr1768 cells over 90 hours under both high light (130 µmol m⁻² s⁻¹) and low light (30 µmol m⁻² s⁻¹).
