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

objectiveGAANTRY (Gene Assembly in Agrobacterium by Nucleic acid Transfer using Recombinase technologY) is a flexible and effective system for stably stacking multiple genes within an Agrobacterium virulence plasmid Transfer-DNA (T-DNA). We examined the ability of the GAANTRY Agrobacterium rhizogenes ArPORT1 '10-stack' strain to generate transgenic potato plants.

resultsThe 28.5 kilobase 10-stack T-DNA, was introduced into Lenape potato plants with a 32% transformation efficiency. Molecular and phenotypic characterization confirmed that six of the seven tested independent transgenic lines carried the entire desired construct, demonstrating that the GAANTRY 10-stack strain can be used can be used in a tissue culture-based callus transformation method to efficiently generate transgenic potato plants. Analysis using droplet digital PCR showed that most of the characterized events carry one or two copies of the 10-stack transgenes and that 'backbone' DNA from outside of the T-DNA was absent in the transgenic plants. These results demonstrate that the GAANTRY system efficiently generates high quality transgenic potato plants with a large construct of stacked transgenes.
