Metabolite Profiles Across Developmental Stages of Waxy Sorghum

1,324 metabolites from 12 classes were measured across eight developmental stages and fifteen tissues of the 'Hongyingzi' waxy sorghum landrace. The dataset provides a spatiotemporal map of metabolic changes, constructed by Jibin Wang and published in 2026. It integrates metabolomic and transcriptomic data to build a regulatory network.

Use Cases

• Identify tissue-specific metabolite accumulation patterns (e.g., phytohormones in stems/grains, allelopathicals in roots) using metabolite class and tissue stage columns.
• Train models to predict metabolite class (e.g., antibacterial alkaloids, immunostimulatory nucleoside bases) based on tissue type and developmental stage features.
• Analyze co-expression networks linking specific metabolites (e.g., flavonoids) to regulatory genes like C-glycosyltransferase (CGT) and MYB transcription factors.
• Study lipid metabolism dynamics by examining features related to the phospholipase D (PLD) gene and associated metabolites in root tissues.

Strengths

• Covers 1,324 distinct metabolites belonging to 12 chemical classes.
• Samples collected from 15 tissues across 8 key developmental stages for temporal analysis.
• Integrates metabolomic and transcriptomic data to construct a regulatory network.

Limitations

• The dataset is small (1.0 MB), suggesting it contains summary or processed data rather than raw instrument outputs.
• Sample size (number of biological replicates) per tissue and stage is not specified, limiting statistical power assessment.
• Geographic and genetic scope is limited to a single landrace ('Hongyingzi'), reducing generalizability.
