The effect of PG depletion on the pigment content of pgsA cells. A, Absorption spectra of cell suspensions of the pgsA mutant of Synechocystis PCC6803; solid line, cells grown in the presence of PG (20 μm); broken line, cells after 5 d of PG depletion; dotted line, cells after 21 d of PG depletion. The spectra were normalized at 625 nm. B, Changes in phycocyanin (left) and Chl (right) contents in the pgsA mutant cells during PG depletion. Each value was calculated from three independent experiments.
