1 · What the graph read from 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.

2 · The registry

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

Cytosine deaminase (CD), produced by prokaryotes but not by higher eukaryotes including plants, deaminates cytosine to uracil. The enzyme likewise converts 5-fluorocytosine (5FC), which by itself is not toxic, to 5-fluorouracil (5FU), which is toxic. The Escherichia coli codA-coding sequence encoding CD, together with appropriate regulatory elements, was introduced into Arabidopsis. Neither untransformed controls, nor transgenic plants expressing no CD mRNA, were sensitive to 5FC. Conversely, for most transgenic plants expressing CD mRNA, in the presence of 5FC calli and seedlings failed to proliferate, and seeds failed to germinate. A few transgenic plants with many codA copies expressed less CD mRNA and remained insensitive to 5FC, which likely reflected epigenetic repeat-induced gene silencing. Thus 5FC, presumably through conversion by the enzyme to 5FU, can be used to select against plants that express CD.
