Fig. 6.
Photosystem II content and function. a Content of [PSII]active versus PSII protein subunit PsbA. Dotted line indicates 1:1 ratio. b Functional rate constant for repair of [PSII]inactive (krecinact; Table 3) versus rate constant for removal of PsbA protein. Dotted line indicates 1:1 ratio. c Rate constant for removal of PsbA protein versus the ratio of PsbA: [PSII]active. Filled circle, Micromonas NCMA 1646 grown at 20 °C and 36 μmol photons m−2 s−1. Open circle, Micromonas NCMA 1646 grown at 20 °C and 185 μmol photons m−2 s−1. Filled triangle, Micromonas NCMA 2099 grown at 2 °C and 36 μmol photons m−2 s−1. Open triangle, Micromonas NCMA 2099 grown at 10 °C and 36 μmol photons m−2 s−1. Mean of n = 3–4 determinations from separate cultures; ±SEM
