Mg-protoporphyrin IX signaling in Cyanidioschyzon merolae: multiple pathways may involve the retrograde signaling in plant cells.
Article in Plant signaling & behavior, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Plastids and mitochondria are organelles in plant cells, which are considered to have evolved from endosymbiotic associations of bacteria. These organelles have their own genomes descended from their ancestors, and the organelle DNA replications (ODR) of plant cells are coordinated with the nuclear DNA replication (NDR) as ODR precedes NDR during a cell cycle progression. However, the underlying mechanism for this coordination remains largely to be determined. Recently, we identified that a tetrapyrrole compound, Mg-Protoporphyrin IX (Mg-Proto), is a cell cycle coordinator from organelle to NDR in plant cells.1 While Mg-Proto has been suggested to be a retrograde plastid signal to modulate transcription of nuclear genes for plastid proteins, our results indicated that nuclear transcriptional regulation is not involved in the NDR induction in C. merolae. Thus, our finding for the NDR control is likely to represent a novel signaling mechanism independent of the conventional plastid signal, which we named "parasitic signal", and suggests multiple Mg-Protoinvolved pathways for the plastid-nucleus retrograde signaling.
