Genome-wide identification and expression analyses of CYP450 genes in Chrysanthemum indicum.
Article in BMC genomics, 2025. 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
backgroundThe cytochrome P450 superfamily comprises a large group of enzymes crucial for the biosynthesis and metabolism of diverse endogenous and exogenous secondary metabolites in plants. Chrysanthemum, an ornamental genus with considerable medicinal value, is one of the most economically important floricultural crops in the world. The characteristics and functions of CYP450 genes in Chrysanthemum species, however, remain largely unknown.
resultsIn this study, we identified 371 CYP450 genes in the Chrysanthemum indicum genome, and categorized them into 8 clans and 44 families through phylogenetic analysis. Gene duplication analysis revealed 111 genes in 47 tandem duplicated clusters and 28 genes in 15 syntenic blocks, suggesting that extensive duplication events may account for the rapid expansion of CiCYP450 superfamily. Additionally, extensive variations in gene structure, motif composition, and cis-regulatory element likely enhance the functional diversity of CiCYP450 proteins. Volatile metabolomic analysis detected a total of 53 distinct volatile organic compounds across the leaves, stems, and roots of C. indicum, with 19 and 16 compounds being exclusive to leaves and stems, respectively. Transcriptomic analysis identified 248 expressed CiCYP450 genes, with 31, 40, and 88 specifically or preferentially expressed in leaves, stems, and roots, respectively. Further correlation analyses between gene expression levels and compound contents highlighted 36 candidate CiCYP450 genes potentially responsible for the biosynthesis of 47 volatile organic compounds.
conclusionsThe genome-wide analyses of cytochrome P450 superfamily offers essential genomic resources for functional studies of CiCYP450 genes, and is significant for the molecular breeding of Chrysanthemum.
