Gene Expression and Secondary Metabolic Regulation Underlying Variegated Leaf Formation in Sweetpotato.

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
Variegated sweetpotato leaves are of interest for ornamental and functional-food applications, yet the molecular and metabolic basis of their coloration remains poorly understood. A sweetpotato accession with variegated leaves was found incidentally in the field, with rare and vivid Pink-purple coloration in the apical leaves. To investigate the mechanism underlying this interesting phenotype, this material was maintained in the laboratory, and variegated and normal green leaves from this plant were analysed by transcriptome profiling, miRNA sequencing and metabolome analysis. By integrating differential mRNA expression analysis, target-gene prediction, miRNA sequencing and metabolite identification, we screened candidate miRNA-mRNA modules associated with this leaf-colour formation.
