Integrated morphological observation, metabolomics, and transcriptomics to investigate the effect of growth years on the quality of Atractylodes macrocephala Koidz.

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
backgroundAtractylodes macrocephala Koidz. is a medicinal plant in high clinical demand due to its pharmacological efficacy. However, research on its quality dynamics across different growth years remains limited, primarily focusing on transcriptomics, microbiome analysis, and photosynthetic capacity, with studies only extending to three-year-old plants.
resultsThis study examines A. macrocephala over a broader growth span (1, 2, 3, 5, and 10 years), integrating morphological, microstructural, metabolomic, spatial metabolite distribution, and transcriptomic analyses. Morphologically, rhizome weight and length increased with age, and the characteristic "Hejing" structure became more pronounced. Microstructural analysis revealed progressively developed xylem. Metabolomic profiling indicated a decline in sucrose content, alongside increased accumulation of bioactive sesquiterpenoids and phenolic acids over time. Transcriptomic analysis showed that genes involved in the biosynthesis of these active compounds-terpenoid backbone (HMGR, DXS, idi, GPS, and GGPS), phenylpropanoid (PAL, 4CL, and HCT), and sucrose metabolism (SPS and SPP)-were upregulated in older plants. Desorption electrospray ionisation mass spectrometry imaging (DESI-MSI) revealed an expanded distribution of key metabolites with increasing growth years.
conclusionThe findings suggest that A. macrocephala aged 5 and 10 years exhibit superior quality, with a more distinct "Hejing" morphology and higher levels of bioactive compounds. The quality stabilises after five years, indicating that older plants may possess enhanced medicinal value.
