Fig. 2.

Effects of light during preconditioning on the acquisition of chill-light tolerance. Cells were grown in BG11 with glucose at 30°C and pretreated at 15°C for different periods of time. The chill-light tolerance was evaluated as the ability to reinitiate growth (ARG). Empty bars, light of 30 μmol photons m⁻² s⁻¹; solid bars, no light. The inset shows Western blot detection of Rbp1 (the upper band) in Synechocystis treated at 15°C with or without light.
