Figure 5.

Correlation of various analyzed parameters in the isolated gox mutants. A. The linear correlation coefficient R² between each combination of the parameter tested in the 20 gox mutants was calculated and values were translated into a color code according the scale indicated. B. The correlation between ¹O₂ production at HL and deepoxidation of xanthophylls ([Z+A]/[Z+A+V]) at LL (black circles) and HL (grey triangles) is shown. C. Cluster analysis of 20 gox mutants based on GPXH expression, ¹O₂ production, NPQ and pigment contents under either LL or HL condition as shown in Figure 3 and 4. All data are relative to wild-type levels under the same growth condition and shown in a color code according the scale indicated. The nature of different groups of mutants is discussed in the text.
