Figure 7

100-T spectra and fluorescence excitation spectra at 120 K of pea and bean thylakoids. The 100-T (A) and fluorescence excitation centered at 735 nm (C). Spectra for pea (solid line) and bean (dashed line) thylakoids (3 μg Chl ml^-1) were normalized to the area of 100 under the spectrum. Arithmetic difference spectra pea-minus-bean, were calculated for 100-T spectrum (B) as well as for fluorescence excitation spectra centered at 680 nm (dotted line) and 735 nm (solid line) (D).
