Substrate-dependent and organ-specific chloroplast protein import in planta.
Article in The Plant cell, 2004. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 31 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
The NADPH-dependent protochlorophyllide (Pchlide) oxidoreductase (POR) is unique because it is a photoenzyme that requires light for its catalytic activity and uses Pchlide itself as a photoreceptor. In Arabidopsis, there are three structurally related PORs, denoted PORA, PORB, and PORC. The import of one of them, PORA, into plastids of cotyledons is substrate dependent. This substrate dependence is demonstrated in intact seedlings of wild-type Arabidopsis and two mutants, xantha2, which is devoid of Pchlide, and flu, which upon redarkening rapidly accumulates Pchlide. In true leaves, PORA uptake does not require the presence of Pchlide. The organ specificity of the substrate-dependent import of PORA reveals a means of controlling plastid protein translocation that is closely associated with a key step in plant development, the light-dependent transformation of cotyledons from a storage organ to a photosynthetically active leaf.
