a, Light-induced P700 oxidation in mature PSI preparations from P. sativum (red) and A. sativa (blue). Results of three independent measurements of light-induced P700 photo-oxidation in respective experiments are shown in the table. b, Chlorophyll/P700 ratio of the A. sativa pre-PSI-1 (red) that contains 88 chlorophylls compared with mature PSI from P. sativum with 154 chlorophylls (blue). c, Light-induced P700 photo-oxidation and P700+ reduction of mature PSI from A. sativa with different Pc concentrations: 4.8 µg (black), 14.3 µg (grey), 47.6 µg (blue) and 47.6 µg (green) of Pc + 200 mM NaCl. d, Light-induced P700 photo-oxidation and P700+ reduction of pre-PSI-1 with different Pc concentrations: 4.8 µg (black), 14.3 µg (grey), 47.6 µg (blue), and 47.6 µg (green) of Pc + 200 mM NaCl, and 47.6 µg of PC + 400 mM NaCl (orange). Results of three independent measurements of light-induced P700 photo-oxidation in respective experiments are shown in the table. OD, optical density.
