Characterization of a class II 5-enopyruvylshikimate-3-phosphate synthase with high tolerance to glyphosate from Sinorhizobium fredii.
Article in World journal of microbiology & biotechnology, 2014. 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
5-Enopyruvylshikimate-3-phosphate synthase (EPSP synthase) is an important enzyme in the shikimate pathway mediating the biosynthesis of aromatic compounds in plants and microorganisms. A novel class II EPSP synthase AroA S. fredii from Sinorhizobium fredii NGR234 was overexpressed in Escherichia coli BL21. It was purified to homogeneity and its catalytic properties were studied. The enzyme exhibited optimum catalytic activity at pH 8.0 and 50 °C. It was stable below 40 °C, and over a broad range of pH 5.0-9.0. The EPSP synthase was increasingly activated by 100 mM of the chlorides of NH4 (+), K(+), Na(+) and Li(+). Kinetic analysis of AroA S. fredii suggested that the enzyme exhibited a high glyphosate tolerance and high level of affinity for phosphoenolpyruvate, which indicates the enzyme with a high potential for structural and functional studies and its potential usage for the generation of transgenic crops resistant to the herbicide.
