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

The promoter region of tomato (Lycopersicon esculentum) 3-hydroxy-3-methylglutaryl coenzyme A reductase gene 2 (HMG2) has been analyzed using the transient expression of HMG2-luciferase fusions in red fruit pericarp. The mRNA for HMG2 accumulates to high level during fruit ripening, in a pattern that coincides with the synthesis of the carotenoid lycopene. Unlike most promoters, the region that is upstream of the HMG2 TATA element is not required for high-level expression. The 180-bp region containing the TATA element, the 5' untranslated region, and the translation start site are comparable in strength of the full-length 35S cauliflower mosaic virus promoter. Pyrimidine-rich sequences present in the 5' untranslated leader are important in regulating expression. Also, the ATG start region has been found to increase translation efficiency by a factor of 4 to 10. An alternative hairpin secondary structure has been identified surrounding the HMG2 initiator ATG, which could participate in the translational regulation of this locus. HMG2 appears to be a novel class of strong plant promoters that incorporate unusual, positive regulators of gene expression.
