• The effects of hydrostatic pressure treatments on the photosynthetic activities of isolated thylakoids and PSII membranes were studied, and the following results were obtained. (1) The O_2-evolving activity was selectively inhibited by treatment at 200 MPa and above, while the electron transport in the PSII reaction center, as measured by the photoreduction of 2,6-dichlorophenol-indophenol (DCIP) with 1,5-diphenylcarbazide (DPC), was markedly enhanced. (2) The activity of PSI, as measured by the photoreduction of methylviologen with reduced DCIP, was not much affected even after treatment at 500 MPa, whereas this electron transport became uncoupled from phosphorylation at 200 MPa and above. (3) In pressure-treated PSII membranes, the EPR signal of Y^+_Z became photoinducible with the concomitant appearance of an EPR signal for Mn^<2+>. (4) The 33-kDa extrinsic protein was retained in inhibited PSII membranes, but the 17- and 23-kDa extrinsic proteins were lost. (5) Cross-linking of PSII proteins by 1-ethyl-3-(3-dimethylaminopropyl)-carbodiimide (EDC) suppressed the pressure-induced inactivation of the evolution of O_2. (6) In pressure-treated PSII membranes, higher concentrations of DCMU were required to inhibit the photoreduction of DCIP. Features of the pressure-induced inhibition of various reactions in photosynthetic membranes are discussed on the basis of these results.
