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 wide variety of sesquiterpenoids have been isolated from basidiomycetes, and their bioactive properties have attracted significant attention in an effort to understand biosynthetic machineries. As both sesquiterpene synthases and cytochrome P450 monooxygenases play key roles in the diversification of sesquiterpenoids, it is important to widely and mutually understand their biochemical properties. In this study, we performed genome-wide annotation and functional characterization of sesquiterpene synthases from the brown-rot basidiomycete Postia placenta. Using RT-PCR, we isolated 16 sesquiterpene synthases genes as full-length cDNAs. Heterologous expression revealed that the sesquiterpene synthases could produce a series of sesquiterpene scaffolds with distinct metabolic profiles. Based on metabolic studies, we identified 25 sesquiterpene scaffolds including Δ6-protoilludene produced by the sesquiterpene synthases. In particular, a protoilludene synthase from the brown-rot basidiomycete was characterized for the first time. Furthermore, we conducted a semi-comprehensive functional screening of cytochrome P450 monooxygenases from P. placenta to elucidate biosynthetic machineries involved in metabolisms of Δ6-protoilludene. Coexpression of protoilludene synthase and 184 isoforms of cytochrome P450 monooxygenases enabled the identification of CYP5344B1, CYP5348E1 and CYP5348J3, which catalysed the hydroxylation reaction of Δ6-protoilludene to produce Δ6-protoilludene-8-ol and Δ6-protoilludene-5-ol. Furthermore, structural isomers of Δ7-protoilludene-6-ol were obtained from incubation of Δ6-protoilludene-8-ol in acidic culture medium.
