Sucrose synthase in unicellular cyanobacteria and its relationship with salt and hypoxic stress.
Article in Planta, 2012. 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
Higher plants and cyanobacteria metabolize sucrose (Suc) by a similar set of enzymes. Suc synthase (SuS, A/UDP-glucose: D: -fructose 2-α-D: -glucosyl transferase) catalyzes a reversible reaction. However, it is in the cleavage of Suc that this enzyme plays an important role in vivo, providing sugar nucleotides for polysaccharide biosynthesis. In cyanobacteria, SuS occurrence has been reported in heterocyst-forming strains, where it was shown to be involved also in nitrogen fixation. We investigated the presence of sequences homologous to SuS-encoding genes (sus) in recently sequenced cyanobacterial genomes. In this work, we show for the first time the presence of SuS in unicellular cyanobacterium strains (Microcystis aeruginosa PCC 7806, Gloebacter violaceus PCC 7421, and Thermosynechococcus elongatus BP-1). After functional characterization of SuS encoding genes, we demonstrated an increase in their transcript levels after a salt treatment or hypoxic stress in M. aeruginosa and G. violaceus cells. Based on phylogenetic analysis and on the presence of sus homologs in the most recently radiated cyanobacterium strains, we propose that sus genes in unicellular cyanobacteria may have been acquired through horizontal gene transfer. Taken together, our data indicate that SuS acquisition by cyanobacteria might be related to open up new ecological niches.
