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

Base editors enable precise nucleotide changes at targeted genomic loci without requiring double-stranded DNA breaks or repair templates. TALE-adenine base editors (TALE-ABEs) are genome editing tools, composed of a DNA-binding domain from transcription activator-like effectors (TALEs), an engineered adenosine deaminase (TadA8e), and a cytosine deaminase domain (DddA), that allow A•T-to-G•C editing in human mitochondrial DNA. However, the editing ability of TALE-ABEs in plants apart from chloroplast DNA has not been described, so far, and the functional role how DddA enhances TadA8e is still unclear. We tested a series of TALE-ABEs with different deaminase fusion architectures in Nicotiana benthamiana and rice. The results indicate that the double-stranded DNA-specific cytosine deaminase DddA can boost the activities of single-stranded DNA-specific deaminases (TadA8e or APOBEC3A) on double-stranded DNA. We analysed A•T-to-G•C editing efficiencies in a β-glucuronidase reporter system and showed precise adenine editing in genomic regions with high product purity in rice protoplasts. Furthermore, we have successfully regenerated rice plants with A•T-to-G•C mutations in the chloroplast genome using TALE-ABE. Consequently, TALE-adenine base editors provide alternatives for crop improvement and gene therapy by editing nuclear or organellar genomes.
