Comparison of the relative amounts of chlorophyll, fatty acid, and protein together with fluorescence parameters in wild-type and mutant leaves

Wild Typefad3-2 fad7-2 fad8

Total chlorophyll (mg g−1 fresh wt)1.64 ± 0.101.33 ± 0.09
Protein (mg g−1 fresh wt)24.55 ± 1.4022.15 ± 1.80
Fatty acids (μg g−1 fresh wt)6.29 ± 0.656.26 ± 0.28
F v/F m 0.759 ± 0.0050.769 ± 0.005
ΦII 0.575 ± 0.0070.578 ± 0.007

Plants were grown at 22°C and under continuous illumination of 125 μmol m−2 s−1. Fluorescence measurements were made at 25°C. Values are means ± se of 25 leaves from five independent experiments.
