FIGURE 8.

RT-quantitative PCR analysis of the accumulation of transcript for subunits of the cytochrome b₆f complex in WT, cpld38, and cpld38-CPLD38. The transcript levels for cpld38-CPLD38_1 and cpld38-CPLD38_2 were similar and were averaged to give the level of transcript in the complemented strain. The accumulation of petA, petB, PETC, PETM, and PETN transcripts was measured when the strains were in their exponential growth phase in low light (40 μmol photons m⁻² s⁻¹). Levels of individual transcripts are evaluated with respect to the transcript abundance of the housekeeping control gene (CBLP). The WT transcript level has been set to 100% with each strain adjusted accordingly.
