Figure 3.

The restoration of photosynthetic activity. The pgsA mutant cells grown under LL conditions for 5 d without PG were first incubated under HL conditions (white circle) for 120 min, and thereafter, the restoration of photosynthetic activity was monitored under LL conditions in the presence (black square) or absence (black circle) of PG. The arrow indicates the time for the addition of PG to the medium. Photosynthetic activities are indicated as relative values compared with that before treatments. The values are averages of three independent experiments, and the bars represent the sd.
