Comprehensive molecular analysis of arginase-encoding genes in common wheat and its progenitor species.
Article in Scientific reports, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Arginase (ARG) contributes to nitrogen remobilization by conversion of arginine to ornithine and urea. However, wheat ARG genes have not yet been identified. Here we isolated and characterized ARG genes from wheat and its progenitor species and found that a single copy was present in wheat progenitors. Three common wheat ARG genes of TaARG-2AS, TaARG-2BS, and TaARG-2DS were experimentally assigned to the short arms of the group 2 chromosomes. We found an in-frame stop codon in TaARG-2AS, but not in the other two genes. The highest expression was detected in stems and sheaths for TaARG-2BS and in leaves for TaARG-2DS. Both genes have similar expression trend in different developmental stages, peaking at booting and grain filling stages. TaARG-2BS transcript was induced by high salinity and drought, whereas TaARG-2DS was induced by drought only, but neither of them were induced by low temperature. In addition, both genes showed analogous expression pattern upon powdery mildew (PM) infection in the resistant line Pm97033, with TaARG-2BS induced greatly at 72 h post PM infection. In contrast, no obvious transcripts were accumulated for TaARG-2DS in the PM susceptible line Wan7107. Monocot ARGs have more conserved mitochondrion-targeting signals and are more evolutionarily conserved than dicot ARGs.
