32. In eukaryotic photoautotrophs, photosynthesis and general cell metabolism occur separately in the chloroplast and mitochondria. Thus, under normal conditions, eukaryotic plants remain in state 1 at night. However, R. Belkhodja et al. [Photoynth. Res. 56, 265 (1998)] reported a nocturnal reduction of the PQ pool under iron-limiting conditions in terrestrial plants and eukarotic algae (presumably by chlororespiration), which caused increased background fluorescence.
33. Synechococcus was grown at 25°C under a 12-hour light-12-hour dark cycle at 250 μmol of quanta per square meter per second. State 2 transitions were studied during the first ≈55 min of darkness after the 12-hour photoperiod using the FRRf (7, 8). State 1 transitions were induced immediately thereafter by exposing cells to PSI-specific far-red light [light-emitting diode (LED) source with Schott RG-695 long-pass filter]. State transition experiments were conducted during the first few days after the onset of nitrate or iron starvation. PSI and PSII concentrations were determined according to methods described by Dubinsky et al. [Z. Dubinsky, P. G. Falkowski, K. Wyman, Plant Cell Physiol. 27, 1335 (1986)].
34. 2 per photon) were observed despite the clear induction of state 2 transitions and their reversal upon exposure to far-red light (Fig. 4).
