Heterodimerization of type II phytochromes in Arabidopsis.
Article in Proceedings of the National Academy of Sciences of the United States of America, 2004. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 56 papers, 1 of them a synthesis that pooled it.
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
Coimmunoprecipitation of members of the phytochrome red/farred photoreceptor family from plant extracts has been used to analyze their heteromeric binding interactions. Phytochrome (phy)B or phyD apoproteins with six myc epitopes fused to their N termini are biologically active when expressed in Arabidopsis. Immunoprecipitation of either of these tagged proteins from seedling extracts coprecipitates additional type II phytochromes: six myc (myc6)-phyB coprecipitates phyC-phyE; and myc6-phyD coprecipitates phyB and phyE. No interaction of the epitope-tagged proteins with type I phyA was detected. Gel filtration chromatography shows that all five of the Arabidopsis phytochromes are present in seedlings as dimers, and that the heteromeric type II phytochrome complexes migrate at molecular masses characteristic of heterodimers. Similar levels of heterodimer formation are observed in extracts of dark-grown seedlings, where the phytochromes are cytosolic, and light-grown seedlings, where they are predominantly nuclear. These findings indicate that Arabidopsis, which until now has been thought to contain five homodimeric forms of phytochrome, in fact contains multiple species of both homodimeric and heterodimeric phytochromes. The conservation of the phytochrome family throughout angiosperms suggests that heterodimeric red/far-red receptors may be present in many flowering plants.
