Metabolomic and Transcriptomic Analyses Reveal the Molecular Mechanism of Flower Color Variations in

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
background
methodsThis study used the petals of the Rosa 'Rainbow's End' cultivar at four developmental stages (R1, R2, R3, and R4) for targeted metabolomic and transcriptomic analyses.
resultsTargeted metabolomic analyses revealed that the majority of anthocyanidin metabolites were highest at stages R2 and R3 and lowest at R1 and R4. In contrast, most carotenoid metabolites reached their highest levels at R1 and declined continuously from R2 to R4. These results were consistent with the color phenotype of Rosa 'Rainbow's End' petals and suggested that both anthocyanins and carotenoids play critical roles in flower color variation. Specifically, an upregulation of
conclusionsRosa 'Rainbow's End' is an excellent model for studying variations in flower color. The expression patterns of the identified structural genes involved in anthocyanin and carotenoid biosynthesis pathways, along with the related MYB transcription factors, were aligned with the levels of metabolite changes in the petals of four flowering stages. These genes and transcription factors are likely responsible for the color shifts in Rosa 'Rainbow's End'. This study clarifies the mechanisms underlying color changes in Rosa 'Rainbow's End' and provides a theoretical basis for future flower breeding efforts.
