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 transcriptional comparison of wild type and a secondary metabolite deficient Trichoderma virens mutant resulted in the identification of six genes similar to those involved in secondary metabolism in other fungi, including four cytochrome P450 genes, one O-methyl transferase and one terpene cylase. Four of the genes (three cytochrome P450s and the cyclase) are located as a cluster. Transcript levels of three of the P450 genes, the O-methyl transferase and the terpene cyclase were measured. These genes are underexpressed in the mutant, which lacks the major secondary metabolites produced by this strain, viridin and viridiol. Expression levels of clones from the differential library with similarity to fungal trehalose synthase and a hydrophobin were also underexpressed in the mutant, while a heat shock protein hsp98 homolog was not. Based on the gene expression pattern and associated secondary metabolite profile, along with similarity to other secondary metabolism pathways in related fungi, we predict that the cluster is associated with the production of a terpene. The terpene could be viridin. This is the first report on cloning of secondary metabolism related genes from T. virens, and of their organization in a cluster, in this biocontrol fungus.
