Figure 4

Biochemical characterization of thylakoid membrane composition under high light stress. Chlorophylls (A, C), carotenoids (B) and tocopherol (D) content of WT and lut2npq1 plants were measured on leaf acetone extracts as described in "Material and Methods". (E, F) Stoichiometry between photosynthetic pigment-binding complexes under high light stress. PSII/PSI ratio (E) and biochemical antenna size (LHCII/PS ratio, F) were determined by both non-denaturing Deriphat-PAGE and immunoblot-titration using specific antibodies (see "Material and Methods" for details). Symbols and error bars show respectively means ± SD.
