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

Single amino acid substitutions at either of two crucial positions in acetolactate synthase (ALS) result in a chlorsulfuron-insensitive form of this enzyme and, as a consequence, a herbicide-resistant phenotype. Here, we describe the successful in vivo targeting of endogenous tobacco (Nicotiana tabacum) ALS genes using chimeric RNA/DNA and all-DNA oligonucleotides at two different locations. Similar number of conversion events with two different chimeras indicates the absence of restricting influence of genomic target sequence on the gene repair in tobacco. Chlorsulfuron-resistant plants were regenerated from calli after mesophyll protoplast electroporation or leaf tissue particle bombardment with these specifically constructed chimeras. Sequence analysis and enzyme assays proved the resulting alterations to ALS at both DNA and protein levels. Furthermore, foliar application of chlorsulfuron confirmed the development of resistant phenotypes. Lines with proline-196-alanine, threonine, glutamine, or serine substitutions or with tryptophan-573-leucine substitutions were highly resistant at both cellular and whole plant levels, whereas lines with proline-196-leucine substitutions were less resistant. The stability of these modifications was demonstrated by the continuous growth of calli on chlorsulfuron-containing medium and by the transmission of herbicide resistance to progeny in a Mendelian manner. Ability of haploid state to promote chimera-mediated conversions is discussed.
