Regulation of psbA and psaE expression by light quality in Synechocystis species PCC 6803. A redox control mechanism.
Article in Plant physiology, 2001. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 34 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
We investigated the influence of light of different wavelengths on the expression of the psbA gene, which encodes the D1 protein of the photosystem II and the psaE gene, which encodes the subunit Psa-E of the photosystem I, in Synechocystis sp PCC 6803. In an attempt to differentiate between a light-sensory and a redox-sensory signaling processes, the effect of orange, blue, and far-red light was studied in the wild-type and in a phycobilisome-less mutant. Transferring wild-type cells from one type of illumination to another induced changes in the redox state of the electron transport chain and in psbA and psaE expression. Blue and far-red lights (which are preferentially absorbed by the photosystem I) induced an accumulation of psbA transcripts and a decrease of the psaE mRNA level. In contrast, orange light (which is preferentially absorbed by the photosystem II) induced a large accumulation of psaE transcripts and a decrease of psbA mRNA level. Transferring mutant cells from blue to orange light (or vice versa) had no effect either on the redox state of the electron transport chain or on the levels of psbA and psaE mRNAs. Thus, light quality seems to regulate expression of these genes via a redox sensory mechanism in Synechocystis sp PCC 6803 cells. Our data suggest that the redox state of one of the electron carriers between the plastoquinone pool and the photosystem I has opposite influences on psbA and psaE expression. Its reduction induces accumulation of psaE transcripts, and its oxidation induces accumulation of psbA mRNAs.
