Comparison of oxygen evolution rates of the wild type (WT), PSBR knockdown strains, and FUD39. A, Cells were grown with LL in TAP medium. Oxygen evolution measurements were carried out with cells incubated in TAP medium containing 0.15 μm 2-phenyl-1,4-benzoquinone. Values are means ± sd of three replicates. B, Cell culture of the wild-type and ami-RNA-psbr lines were harvested in HSM at HL (200 μE m⁻² s⁻¹) for 24 h. FUD39 was first treated with HL in TAP medium for 24 h. Oxygen evolution measurements were carried out with cells incubated in HSM and TAP medium containing 0.12 μm 2-phenyl-1,4-benzoquinone. Values are means ± sd of three replicates. Chl, Chlorophyll.
