Cloning and functional characterization of sesquiterpene synthase genes from Inonotus obliquus using a Saccharomyces cerevisiae expression system.

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.
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
Inonotus obliquus (Chaga mushroom) is a large medicinal and edible fungus that contains a wealth of bioactive terpenoids. However, the detection of certain low-abundance sesquiterpenoids remains a challenge due to limitations in extraction and analytical techniques. Furthermore, the synthase genes responsible for the biosynthesis of the identified terpenoids have not yet been clearly elucidated. To address this, our study combined transcriptome mining with yeast heterologous expression to investigate the synthase genes involved in sesquiterpenoid production in I. obliquus. We successfully identified eight sesquiterpene synthase genes and one farnesyltransferase. Among these, only cis-β-farnesene, synthesized by IoTPS2, had been previously detected before in the sclerotium of I. obliquus, while the other nine sesquiterpenoids-including neoisolongifolene-8-ol, β-longipinene, vetiselinenol, isolongifolene, 7,8-dehydro-8a-hydroxy-, 4a,8b,10b,11a-tetramethylbicyclo[6.3.0]undec-1-en-5-one, 6,11-oxido-acor-4-ene, β-maaliene, neointermedeol, and longifolenaldehyde-were discovered for the first time. This research provides a critical scientific foundation for expanding the known repertoire of sesquiterpenoids and their corresponding synthase genes in I. obliquus.
