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

The Cas12j-8 nuclease, derived from the type V CRISPR system, is approximately half the size of Cas9 and recognizes a 5'-TTN-3' protospacer adjacent motif sequence, thus potentially having broad application in genome editing for crop improvement. However, its editing efficiency remains low in plants. In this study, we rationally engineered both the crRNA and the Cas12j-8 nuclease. The engineered crRNA and Cas12j-8 markedly improved genome editing efficiency in plants. When combined, they exhibited robust editing activity in soybean and rice, enabling the editing of target sites that were previously uneditable. Notably, for certain target sequences, the editing activity was comparable to that of SpCas9 when targeting identical sequences, and it outperformed the Cas12j-2 variant, nCas12j-2, across all tested targets. Additionally, we developed cytosine base editors based on the engineered crRNA and Cas12j-8, demonstrating an average increase of 5.36- to 6.85-fold in base-editing efficiency (C to T) compared with the unengineered system in plants, with no insertions or deletions (indels) observed. Collectively, these findings indicate that the engineered hypercompact CRISPR/Cas12j-8 system serves as an efficient tool for genome editing mediated by both nuclease cleavage and base editing in plants.
