Multi-Omics Analysis of Yam Tuber Development Under Different Planting Densities

An integrated transcriptomic and metabolomic analysis of Chinese yam (Dioscorea opposita Thunb. cultivar 'W48') tuber development under different planting density stress. The dataset was created by Peng Wang and published on figshare under a CC-BY-4.0 license, last updated on 2026-05-19. It likely contains results from morphological, physiological, and molecular analyses conducted 110 days after planting.

Use Cases

• Identify differentially expressed genes (DEGs) associated with yam tuber thickening based on transcriptomic data.
• Analyze differentially accumulated metabolites (DAMs) enriched in pathways like carotenoid biosynthesis.
• Study the role of plant hormone signal transduction pathways in tuber cell enlargement.
• Validate core regulatory factors like ARF11, ERF1, and ERF5-like identified through WGCNA analysis.

Strengths

• Integrated multi-omics approach combining transcriptomic and metabolomic data.
• Focus on a specific, well-defined experimental condition (planting density stress on cultivar 'W48').
• Analysis includes morphological, physiological, and molecular levels as described in the study.

Limitations

• Row count and specific column definitions are unknown, requiring manual inspection after download.
• The dataset is small (319.1 KB), indicating a limited scope, likely containing summary results rather than raw sequencing data.
• Column-level documentation is absent; field semantics must be inferred from the accompanying research article.
