Redox-regulated RNA helicase expression.
Article in Plant physiology, 2000. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 24 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
In photosynthetic organisms it is becoming increasingly evident that light-driven shifts in redox potential act as a sensor that initiates alterations in gene expression at both the level of transcription and translation. This report provides evidence that the expression of a cyanobacterial RNA helicase gene, crhR, is controlled at the level of transcription and mRNA stability by a complex series of interacting mechanisms that are redox regulated. Transcript accumulation correlates with reduction of the electron transport chain between Q(A) in photosystem II and Q(O) in cyt b(6)f, when Synechocystis sp. strain PCC 6803 is cultured photoautotrophically or photomixotrophically and subjected to darkness and/or electron transport inhibitors or illumination that preferentially excites photosystem II. crhR mRNA stability is also regulated by a redox responsive mechanism, which differs from that affecting accumulation and does not involve signaling initiated by photoreceptors. The data are most consistent with plastoquinol/cyt b(6)f interaction as the sensor initiating a signal transduction cascade resulting in accumulation of the crhR transcript. Functionally, CrhR RNA unwinding could act as a linker between redox regulated transcription and translation. The potential for translational regulation of redox-induced gene expression through RNA helicase-catalyzed modulation of RNA secondary structure is discussed.
