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

A novel 4-hydroxyphenylpyruvate dioxygenase gene (designated as Smhppd) was cloned from hairy roots of Salvia miltiorrhiza Bung. The full-length cDNA of Smhppd was 1,736 bp long with an ORF (open reading frame) that putatively encoded a polypeptide of 481 amino acids, with a predicted molecular mass of 52.54 kDa. The deduced amino acid sequence of the Smhppd gene shared high homology with other known HPPDs. Analysis of Smhppd genomic DNA revealed that it contained two exons and one intron. The analysis of Smhppd promoter region was also presented. Southern-blot analysis revealed that the Smhppd was a low-copy gene in S. miltiorrhiza. Real-time quantitative PCR analysis indicated that Smhppd was constitutively expressed in roots, stems and leaves of S. miltiorrhiza, with the high expression in roots. In addition, Smhppd expression level under different stress condition was also analyzed during the hairy root culture period, including signaling components for plant defence responses, such as methyl jasmonate and salicylic acid, as well as an abiotic elicitor, Ag(+) and a biotic elicitor, yeast extract. This study will enable us to further understand the role Smhppd plays in the synthesis of active pharmaceutical compounds in S. miltiorrhiza at molecular level.
