Overexpressed glutamine synthetase gene modifies nitrogen metabolism and abiotic stress responses in rice.
Article in Plant cell reports, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 84 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
Glutamine synthetase (GS; EC 6.3.1.2) is a key enzyme in nitrogen metabolism; it catalyzes the critical incorporation of inorganic ammonium into glutamine. Two full-length cDNAs that encode the rice (Oryza sativa) cytosolic glutamine synthetase1 genes (OsGS1;1 and OsGS1;2) were isolated from a Minghui 63 normalized cDNA library, and glnA encoding GS in Escherichia coli was isolated by PCR amplification. Transformants for GS gene (GS1;1, GS1;2, and glnA) in rice were produced by an Agrobacterium tumefaciens-mediated transformation method, and transcripts of GS gene accumulated at higher levels in the primary transgenic plants. Our results indicated an increased metabolic level in GS-overexpressed plants, which showed higher total GS activities and soluble protein concentrations in leaves and higher total amino acids and total nitrogen content in the whole plant. Decreases in both grain yield production and total amino acids were observed in seeds of GS-overexpressed plants compared with wild-type plants. In addition, GS1;2-overexpressed plants exhibited resistance to Basta selection and higher sensitivity to salt, drought, and cold stress conditions, whereas the other two types of GS-overexpressed plants failed to show any significant changes for these stress conditions compared with wild-type plants.
