Data Sheet 2_Integrated metabolomic and transcriptomic analysis of anthocyanin accumulatio

Data Sheet 2_Integrated metabolomic and transcriptomic analysis of anthocyanin accumulation mechanisms in maize kernels of different colors.zip is a multi-omics dataset from figshare, authored by Chao Jiang and last updated on 2026-05-31. It contains metabolomic and transcriptomic data from four fresh-eating maize cultivars with contrasting kernel colors: white, yellow, multicolored, and black. The study identified 49 anthocyanin-related metabolites and 12,557 differentially expressed genes.

Use Cases

• Identify candidate regulatory genes for anthocyanin biosynthesis based on transcriptomic data.
• Correlate metabolite profiles with kernel color phenotypes based on metabolomic data.
• Perform weighted gene co-expression network analysis (WGCNA) based on the gene expression data.
• Compare phenylpropanoid and flavonoid biosynthesis pathways across cultivars based on pathway enrichment results.
• Validate expression correlations for candidate genes like DFR (Zm00001d011438) with total anthocyanin content.

Strengths

• Integrated multi-omics data covering both metabolomic (49 anthocyanin-related metabolites) and transcriptomic (12,557 differentially expressed genes) profiles.
• Clear experimental design comparing four distinct maize cultivars (white, yellow, multicolored, black) across developmental stages.
• Specific candidate genes and transcription factors (e.g., DFR, MYB, bHLH, NAC) are identified and their correlations discussed.
• Dataset is openly shared under a CC-BY-4.0 license, facilitating reuse.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is small (171.9 KB), indicating a limited scope, likely summary or processed results rather than raw sequencing data.
