The genetic regulation system AppA/PpsR light dependent was used in purple non-sulfur photosynthetic bacteria (PNSP) R. sphaeroides and R. palustris, using different conditions. For test the system we used as a reporter GFP.

We employed flow cytometery for mesuring the expression of GFP. The conditions we used for test genetic regulation system AppA/PpsR light dependent were: aerobic/darness, anaerobic/light, anaerobic/darknness. The results were as follows.



R. sphaeroides

Results above shows that our system is functional in our two PNSP bacteria.
