Phosphorylation by MPK6: a conserved transcriptional modification mediates nitrate reductase activation and NO production?
Article in Plant signaling & behavior, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
Nitrate reductase is a central enzyme of nitrogen assimilation in plants. In a recent work, we have revealed MPK6 could phosphorylate Arabidopsis NIA2 at the serine 627 in hinge 2 region, this phosporylation may represent a rapid activation mechnism when plant need excessive nitrate reduction. Interestingly, all eukaryotic NRs have conserved docking sequence in their FAD domains, and many plant NR proteins have the conserved MAPK phosphorylation site. Those results indicated the MAPK cascades, the conserved signaling pathway also involved in lateral root development, mediated of NR phosporylation and NO generation. We noticed that the phosphorylation of S627 residue by MPK6 have a specially influence on the NO generation activity of NIA2. Although no homology of mammalian NOS has been identified in plants, NR may still share a similar regulation mechanism with mammalian NOS.
