Increased Septoria musiva resistance in transgenic hybrid poplar leaves expressing a wheat oxalate oxidase gene.

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
A cDNA clone of a wheat germin-like oxalate oxidase (OxO) gene regulated by the constitutive CaMV 35S promoter was expressed in a hybrid poplar clone, Populus x euramericana ('Ogy'). Previous studies showed that OxO is likely to play an important role in several aspects of plant development, stress response, and defense against pathogens. In order to study this wheat oxalate oxidase gene in woody plants, the expression of this gene and the functions of the encoded enzyme were examined in vitro and in vivo in transgenic 'Ogy'. The enzyme activity in the transformed 'Ogy' was visualized by histochemical assays and in SDS-polyacrylamide gels. It was found that the wheat OxO gene is expressed in leaves, stems, and roots of the transgenic 'Ogy' plants and the encoded enzyme is able to break down oxalic acid. Transgenic 'Ogy' leaves were more tolerant to oxalic acid as well as more effective in increasing the pH in an oxalic acid solution when compared to untransformed controls. In addition, when leaf disks from 'Ogy' plants were inoculated with conidia of the poplar pathogenic fungus Septoria musiva, which produces oxalic acid, the OxO-transformed plants were more resistant than the untransformed controls.
