Figure 2

13CMAS NMR spectra of selectively 4-ALA 13C-isotope labeled BBY preparation (a), thylakoid membranes (b) and entire plants (c) of the aquatic plant Spirodela oligorrhiza obtained under continuous illumination (red). Spectra (a’–c’) (grey) show the corresponding spectra obtained under dark conditions. All spectra were obtained at a magnetic field of 4.7 T and a temperature of 235 K with a MAS frequency of 8 kHz and a cycle delay of 4 s.
