Western blot analyses showing effects of preconditioning (A) and chloramphenicol (B) on the level of Rbp1 (the upper band) in Synechocystis under chill-light stress. (A) Synechocystis cells grown at 30°C were exposed to chill-light stress for different periods of time with (I) or without (II) preconditioning at 15°C for 6 days. (B) Synechocystis cells grown at 30°C (lane 1) were directly exposed to chill-light stress for 1 day without (lane 2) or with (lane 3) chloramphenicol or preconditioned for 6 days (lane 4) and exposed to chill-light stress for 4 days without (lane 5) or with (lane 6) chloramphenicol.
