Integrated analysis of transcriptomics and metabolomics of Dendrobium officinale flowers at different developmental stages.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Dendrobium officinale is an edible medicinal herb. Its flowers contain various nutrients and active compounds, the abundance of which differs significantly across developmental stages. However, the molecular mechanisms underlying these variations remain poorly understood. This study employed combined transcriptomic and metabolomic analyses to investigate changes in gene expression and metabolite concentrations in Dendrobium flowers and buds. The analysis identified 2767 differentially expressed genes between the bud (group B) and flower (group F) stages, with 902 up-regulated and 1865 down-regulated in group B relative to group F. The number of differentially abundant secondary metabolites was 221, including 113 up-regulated and 108 down-regulated metabolites. The differential metabolites primarily consisted of lipids and lipid-like molecules, organic heterocyclic compounds, organic acids, and their derivatives, phenylacetones and polyketides, organic oxides, benzene ring-type compounds, hydrocarbons, and alkaloids with their derivatives. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis of the differentially expressed genes and metabolites revealed enrichment in pathways related to phytohormone signaling, phenylpropanoid biosynthesis, and zeaxanthin biosynthesis. Verification of 15 genes through quantitative real-time PCR (qRT-PCR) confirmed the accuracy of the transcriptomic analysis. Taken together, these findings contribute to an improved understanding of the nutritional and pharmacological characteristics of Dendrobium officinale flowers at different developmental stages.
