Collapsing Aged Culture of the Cyanobacterium Synechococcus elongatus Produces Compound(s) Toxic to Photosynthetic Organisms
Figure 4
The TD34-mutant of Synechocystis, which lacks a functional photosystem II reaction center, remains sensitive to conditioned medium (CM).
Shown are wild type Synechocystis PCC6803 (6803) and the mutant in which the three copies of psbA, each encoding the D1 protein of photosystem II, were inactivated (TD34). Cells were inoculated into fresh medium (FM) or CM.
