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

Nucleotide positions conserved on the 3' side of the initiator codon ATG and the corresponding N-terminal amino acid residues in a number of highly abundant plant proteins were identified by computational analysis of a dataset of highly expressed plant genes. The reporter genes uidA and gfp were modified to introduce these features. Insertion of GCT TCC TCC after the initiator codon ATG augmented expression for both the reporter genes. The insertion of each successive codon improved the expression of beta-glucuronidase (GUS) in an incremental fashion in transient transformation of tobacco (Nicotiana tabacum) leaves. The insertion of alanine-serine (Ser)-Ser resulted in about a 2-fold increase in the stability of GUS. However, this did not account for the 30- to 40-fold increase in GUS activity between the constructs coding for methionine-alanine-Ser-Ser-GUS and the native enzyme. Substitution of the codon for Ser at the third amino acid residue with synonymous codons reduced GUS expression. The results suggest a role for the conserved nucleotides in the +4 to +11 region in augmenting posttranscriptional events in the expression of genes in plants.
