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

An efficient method for making directed DNA sequence modifications to plant genes (gene targeting) is at present lacking, thereby frustrating efforts to dissect plant gene function and engineer crop plants that better meet the world's burgeoning need for food, fibre and fuel. Zinc-finger nucleases (ZFNs)-enzymes engineered to create DNA double-strand breaks at specific loci-are potent stimulators of gene targeting; for example, they can be used to precisely modify engineered reporter genes in plants. Here we demonstrate high-frequency ZFN-stimulated gene targeting at endogenous plant genes, namely the tobacco acetolactate synthase genes (ALS SuRA and SuRB), for which specific mutations are known to confer resistance to imidazolinone and sulphonylurea herbicides. Herbicide-resistance mutations were introduced into SuR loci by ZFN-mediated gene targeting at frequencies exceeding 2% of transformed cells for mutations as far as 1.3 kilobases from the ZFN cleavage site. More than 40% of recombinant plants had modifications in multiple SuR alleles. The observed high frequency of gene targeting indicates that it is now possible to efficiently make targeted sequence changes in endogenous plant genes.
