Targeted deletion of grape retrotransposon associated with fruit skin color via CRISPR/Cas9 in Vitis labrascana 'Shine Muscat'.
Article in PloS one, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Transposition of transposable elements affect expression levels, splicing and epigenetic status, and function of genes located in, or near, the inserted/excised locus. For example, in grape, presence of the Gret1 retrotransposon in the promoter region of the VvMYBA1a allele at the VvMYBA1 locus suppress the expression of the VvMYBA1 transcription factor gene for the anthocyanin biosynthesis and this transposon insertion is responsible for the green berry skin color of Vitis labrascana, 'Shine Muscat', a major grape cultivar in Japan. To prove that transposons in grape genome can be removed by genome editing, we focused on Gret1 in the VvMYBA1a allele as a target of CRISPR/Cas9 mediated transposon removal. PCR amplification and sequencing detected Gret1 eliminated cells in 19 of 45 transgenic plants. Although we have not yet confirmed any effects on grape berry skin color, we were successful in demonstrating that cleaving the long terminal repeat (LTR) present at both ends of Gret1 can efficiently eliminate the transposon.
