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

Stimulation of the homologous recombination DNA-repair pathway via the induction of genomic double-strand breaks (DSBs) by zinc finger nucleases (ZFNs) has been deployed for gene replacement in plant cells. Nonhomologous end joining (NHEJ)-mediated repair of DSBs, on the other hand, has been utilized for the induction of site-specific mutagenesis in plants. Since NHEJ is the dominant DSB repair pathway and can also lead to the capture of foreign DNA molecules, we suggest that it can also be deployed for gene replacement. An acceptor DNA molecule in which a green fluorescent protein (GFP) coding sequence (gfp) was flanked by ZFN recognition sequences was used to produce transgenic target plants. A donor DNA molecule in which a promoterless hygromycin B phosphotransferase-encoding gene (hpt) was flanked by ZFN recognition sequences was constructed. The donor DNA molecule and ZFN expression cassette were delivered into target plants. ZFN-mediated site-specific mutagenesis and complete removal of the GFP coding sequence resulted in the recovery of hygromycin-resistant plants that no longer expressed GFP and in which the hpt gene was unlinked to the acceptor DNA. More importantly, ZFN-mediated digestion of both donor and acceptor DNA molecules resulted in NHEJ-mediated replacement of the gfp with hpt and recovery of hygromycin-resistant plants that no longer expressed GFP and in which the hpt gene was physically linked to the acceptor DNA. Sequence and phenotypical analyses, and transmission of the replacement events to the next generation, confirmed the stability of the NHEJ-induced gene exchange, suggesting its use as a novel method for transgene replacement and gene stacking in plants.
