Chlorophyll content, chlorophyll a/b ratio, and maximal PSII quantum efficiency of wild-type Arabidopsis and galactolipid mutants
| Variable | Wild Type | dgd1 | dgd1GlcT | dgd1dgd2 | dgd1dgd2GlcT |
|---|---|---|---|---|---|
| Chlorophyll (mg m−2) | 342.2 ± 14.9 | 259.2 ± 12.9 | 255.2 ± 19.9 | 178.4 ± 31.7 | 225.2 ± 6.5 |
| Chlorophyll a/b | 3.68 ± 0.07 | 3.12 ± 0.05 | 3.25 ± 0.07 | 2.92 ± 0.10 | 3.17 ± 0.17 |

The maximal PSII quantum efficiency was determined after 15 min of dark adaptation of leaves, so that qE-type quenching was completely relaxed.
