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

Transgene integration complexity in the recipient genome can be an important determinant of transgene expression and field performance in transgenic crops. We provide the first direct comparison of Agrobacterium-mediated transformation (AMT) and particle bombardment using whole plasmid (WP) and excised minimal cassettes (MC), for transformation efficiency, transgene integration complexity and transgene expression in plants. To enable direct comparison, a selectable marker and a luciferase reporter gene were linked in identical configurations in plasmids suitable for AMT or direct gene transfer into sugarcane. Transformation efficiencies were similar between WP and MC when equal molar DNA quantities were delivered. When the MC concentration was reduced from 66 to 6.6 ng per shot, transformation efficiency dropped fourfold, to a level equivalent with AMT in amenable genotype Q117. The highest proportion of transformants combining low copy number (estimated below two integrated copies by qPCR) with expression of the non-selected reporter gene was obtained using AMT (55 %) or MC at low DNA concentration (30 %). In sugarcane, both of these methods yielded high-expressing, single-copy transgenic plant lines at a workable efficiency for practical plant improvement; but AMT is currently limited to a few amenable genotypes. These methods are best coupled with rapid early screens for desired molecular characteristics of transformants, e.g. PCR screens for low copy number and/or transcription of the gene of practical interest.
