Plastid regulation of Lhcb1 transcription in the chlorophyte alga Dunaliella tertiolecta.
Article in Plant physiology, 2004. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 16 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 identify four novel DNA-binding complexes in the nuclear-encoded Lhcb1 promoter of the chlorophyte alga Dunaliella tertiolecta that are regulated by photosynthetic pathways in the plastid. The binding activities of three of the complexes were positively correlated with time-dependent changes in Lhcb1 transcript abundance, implicating their roles as transcriptional enhancers in a retrograde signal transduction pathway. Using a combination of inhibitors, uncouplers, and antimycin A, and by following the kinetic pattern of gene regulation, we infer two different sensors in the signal transduction pathway. On short time scales of 0.5 to about 4 h, the transthylakoid membrane potential appears to be a critical determinant of gene expression, whereas on time scales of 8 h or longer, the redox state of the plastoquinone pool becomes increasingly more important. The differentiation of these two types of signals was observed in parallel effects on gene transcription and on the patterns of DNA-binding activities in the Lhcb1 promoter. These signals appear to be transduced at the nuclear level via a coordinated ensemble of DNA-binding complexes located between -367 and -188 bp from the start codon of the gene. The regulation of these elements allows the cell to up- or down-regulate the expression on Lhcb1 in response to changes in irradiance.
