- W2003552956 abstract "The following arguments in favor of exciton transfer between the two photosystems are presented: (1) MgCl2 (1–10 mM range) decreases the intersystem transfer but does not modify the partition of absorbed photons between the photosystems. MgCl2 addition causes a simultaneous increase of excitation life time (τ) and of fluorescence intensity (F). The same linear relationship is obtained with or without added Mg2+. (2) The deactivation of Photosystem II by the Photosystem II to Photosystem I transfer increases with the level of reduced Photosystem II traps. When all Photosystem II traps are closed, half of Photosystem II excitons are deactivated by transfer to Photosystem I. (3) From the relative values of the 685-nm fluorescence yield and System II electron transport rate in limiting light, measured with and without MgCl2, the values of rate constants of Photosystem II deactivation were calculated. (4) The intersystem transfer determines a 715-nm variable fluorescence, which is lowered by MgCl2 addition. When this transfer is decreased by MgCl2 the efficiency of the transfer between Photosystem II-connected units is enhanced, and a more sigmoidal fluorescence rise is obtained. A double-layer model of the thylakoid membrane where each photosystem is restricted to one leaflet is proposed to explain the decrease of the intersystem transfer after adding cations. It is suggested that MgCl2 decreases the thickness of the Photosystem I polar region, increasing the distance between the pigments of the two photosystems." @default.
