Large-scale mining of plant genomes unlocks the diversity of oxidosqualene cyclases.
Article in Nature chemical biology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
The differential cyclization and rearrangement of 2,3-oxidosqualene controlled by oxidosqualene cyclases (OSCs) represents one of the most complex single enzyme transformations in nature and gives rise to a vast array of triterpenoid diversity in the plant kingdom. Here we systematically mine 599 plant genomes representing 387 species and investigate OSC diversity across different plant lineages. From the OSC sequences identified, 20 were selected for functional evaluation. Through analysis of these enzymes, we discover product profiles within clades previously believed to be functionally conserved and OSCs producing triterpenes for which no enzymatic source was known. We also discover OSCs with product profiles that yield mechanistic insights into the control of specific reaction pathways. Our study reveals lineage-specific blooms of OSC subgroups suggestive of adaptation to different environmental niches, opens up previously inaccessible chemistry and provides a framework for systematic investigations of metabolic diversification and underlying enzymatic mechanisms in the plant kingdom.
