An organ-specific transcriptome atlas of Curcuma wenyujin: MicroRNAs, phasiRNAs, and metabolic pathways.
Article in The plant genome, 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
Curcuma wenyujin Y. H. Chen et C. Ling (C. wenyujin) is a medicinal plant widely used for clinical treatments. In this study, integrated omics data analyses enabled us to discover the microRNAs (miRNAs) and the phased small interfering RNAs (phasiRNAs) on a transcriptome-wide scale. A total of 186 mature miRNAs and 23 precursors were reported. Besides, 31 miRNAs of 14 families were organ-specifically expressed, and 13 of these miRNAs could perform organ-specific target regulation. More than 80% of the phasiRNA loci were organ-specifically expressed, especially in tubers. In some cases, phasiRNAs with distinct increments, but with accordant organ-specific expression patterns, were generated from a highly overlapped region, indicating that different machineries might be synchronously engaged in phasiRNA processing. Based on the transcriptome assembly, 28 and 56 tuber-specific genes were identified to be involved in alkaloid and terpenoid metabolisms, respectively. Analysis of the enzyme-coding genes of the β-elemene biosynthetic pathway showed that the downstream genes were tuber-specific, while the upstream genes were not. We assumed that the precursor metabolites produced in the other organs might be delivered to the tubers for the final steps of β-elemene biosynthesis. Summarily, our report provided an organ-specific transcriptome atlas of C. wenyujin, which could serve as the basis for the molecular studies on organ development and secondary metabolisms in this plant.
