Transcriptome profiling of transgenic potato plants provides insights into variability caused by plant transformation.
Article in PloS one, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Crop genetic engineering involves transformation in which transgenic plants are regenerated through tissue culture manipulations that can elicit somaclonal variation due to mutations, translocations, and/or epigenetic alterations. Here, we report on alterations in the transcriptome in a panel of transgenic potato plants engineered to be herbicide resistant. Using an inbred diploid potato clone (DMRH S5 28-5), ten single-insert transgenic lines derived from independent Agrobacterium-mediated transformation events were selected for herbicide resistance using an allelic variant of acetolactate synthase (mALS1). Expression abundances of the single-copy mALS1 transgene varied in individual transgenic lines was correlated with the level of phenotypic herbicide resistance, suggesting the importance of transgene expression in transgenic performance. Using RNA-sequencing, differentially expressed genes were identified with the proportion of genes up-regulated significantly higher than down-regulated genes in the panel, suggesting a differential impact of the plant transformation on gene expression activation compared to repression. Not only were transcription factors among the differentially expressed genes but specific transcription factor binding sites were also enriched in promoter regions of differentially expressed genes in transgenic lines, linking transcriptomic variation with specific transcription factor activity. Collectively, these results provide an improved understanding of transcriptomic variability caused by plant transformation.
