英文摘要	In our earlier works, we have identified rate-limiting steps in the dark-to-light transition of PSII. By measuring chlorophyll a fluorescence transients elicited by single-turnover saturating flashes (STSFs) we have shown that in diuron-treated samples an STSF generates only F-1 (< F-m) fluorescence level, and to produce the maximum (F-m) level, additional excitations are required, which, however, can only be effective if sufficiently long Ar waiting times are allowed between the excitations. Biological variations in the half-rise time (Delta tau(1/2)) of the fluorescence increment suggest that it may be sensitive to the physicochemical environment of PSII. Here, we investigated the influence of the lipidic environment on Delta tau(1/2) of PSII cote complexes of Thermosynechococcus vulcanus. We found that while non-native lipids had no noticeable effects, thylakoid membrane lipids considerably shortened the Delta tau(1/2), from similar to 1 ms to similar to 0.2 ins. The importance of the presence of native lipids was confirmed by obtaining similarly short Delta tau(1/2 )values in the whole T. vulcanus cells and isolated pea thylakoid membranes. Minor, lipid-dependent reorganizations were also observed by steady-state and time-resolved spectroscopic measurements. These data show that the processes beyond the dark-to-light transition of PSII depend significantly on the lipid matrix of the reaction center.
