Changes in PG content and photosynthetic activity of intact cells of the wild type and the pgsA mutant of Synechocystis sp. after a deprivation of PG from the growth medium. A, Changes in PG content. Wild type (○) and mutant (●) cells grown in the medium containing 20 μm PG were transferred to the medium without PG and incubated for the designated times. The values are averages from two independent experiments. B, Changes in photosynthetic activity. Wild type (●) and mutant (○) cells grown in the medium containing 20 μm PG were transferred to the medium without PG and incubated for the designated times. In the case of the mutant, the culture was divided into two flasks after a deprivation of PG for 6 d. The culture in one flask was further incubated without PG, whereas that in the other was supplemented with 20 μm PG. The arrow indicates the time of addition of PG. The values are averages from two independent experiments.
