From: Combination of long-term 13CO2 labeling and isotopolog profiling allows turnover analysis of photosynthetic pigments in Arabidopsis leaves

Fig. 3

Concentrations of photosynthetic pigments in Arabidopsis plants harvested in the early morning of day 8. a Lutein (Lut) and all-trans-β-carotene (β-Car). b Zeaxanthin (Zea) and antheraxanthin (Anthera). c Violaxanthin (Vio) and neoxanthin (Neo). Carotenoid levels relative to the total chlorophyll content (mmol mol−1 Chl) are shown. d De-epoxidation state (DES) of the xanthophyll cycle calculated as (Anthera + Zea)/(Vio + Anthera + Zea). e Chlorophyll a (Chl a) and chlorophyll b (Chl b) contents per unit leaf mass (μmol g−1 fresh weight). Black triangles represent control plants (n = 4) that stayed in the ambient air outside the labeling chamber. For 13C-labeled samples, red and blue symbols are for plants with higher (n = 12) or lower (n = 3) 13C incorporation in the pigments, respectively. The latter showed visible stress symptoms (see Additional file 1: Fig. S3b for images of the plants). The box plots are based on all data. The thick horizontal line inside the box shows the median. The middle 50% of the data fall between the upper and lower end of the box. Data beyond the whisker boundaries are outliers
