Chestnut Bud Abscission Multi-Omics Data on Hormones, Genes, and Metabolites

Multi-omics data from a study of programmed cell death in Chinese chestnut buds includes hormone quantification, transcriptomic, and metabolomic profiles. The analysis identified 4,731 differentially expressed genes and 345 differentially accumulated metabolites during key developmental stages. The dataset was authored by Yan Guo and uploaded to figshare in April 2026.

Use Cases

• Identify key hormone dynamics by analyzing quantified levels of cytokinins, auxin precursors, ABA, jasmonic acid, and ethylene across bud development stages.
• Train models to predict bud abscission status using the 4,731 differentially expressed gene (DEG) profiles and 345 differentially accumulated metabolite (DAM) levels.
• Construct co-regulatory networks by integrating transcriptomic data on DEGs enriched in plant hormone signal transduction with metabolomic data on secondary metabolite biosynthesis pathways.
• Analyze temporal patterns in gene expression and metabolite accumulation by comparing data from the S25 and S30 bud developmental stages.

Strengths

• Integrated multi-omics data covering hormone quantification, transcriptomics (4,731 DEGs), and widely targeted metabolomics (345 DAMs).
• Clear temporal resolution with data from two key bud developmental stages (S25 and S30).
• Data supports pathway enrichment analysis for processes like plant hormone signal transduction and secondary metabolite biosynthesis.

Limitations

• Small dataset scale at 2.5 MB, suggesting limited raw sequence data or a focused subset of processed results.
• Sample size is limited to two chestnut cultivars ('Tima Zhenzhu' and 'Dabanhong'), restricting genetic diversity.
• Unknown row count for the primary data tables within the Excel file.
