Abstract excerpt
The photosystem II (PSII) double mutant delta PsbO:delta PsbU was unable to grow photoautotrophically at pH 7.5, but growth was restored at pH 10. We have isolated a pseudorevertant of this strain, which exhibited photoautotrophic growth at pH 7.5. PSII-specific oxygen evolution and assembled PSII centers in the pseudorevertant and the original delta PsbO:delta PsbU strains were similar at pH 7.5. Comparison of...
