Ethylene Repression of Nicotine Biosynthesis in Tobacco: Transcriptome Analysis

Data Sheet 1_Ethylene represses jasmonate signaling to attenuate nicotine biosynthesis in Nicotiana tabacum.doc contains transcriptome analysis data from a study by Yongqiang Ding, last updated in April 2026. The dataset likely contains results from an experiment treating tobacco with ethephon, an ethylene-releasing compound, over 2, 4, 8, and 24-hour intervals. Analysis identified over 6000 differentially expressed genes and enrichment in pathways related to nicotine biosynthesis.

Use Cases

• Identify differentially expressed genes in response to ethylene treatment based on the transcriptome analysis.
• Analyze enrichment in pyridine nucleotide metabolic pathways based on GO and KEGG analysis results.
• Study the repression of key regulators like COI1 and ERF189/199 based on the gene expression data.
• Investigate co-expression networks for candidate regulatory genes based on the analysis of ERF189/199.

Strengths

• Identifies over 6000 differentially expressed genes, providing a substantial gene set for analysis.
• Includes time-series data across four time points (2, 4, 8, and 24 hours) for tracking expression dynamics.
• Enrichment analysis links results to specific biological pathways like 'pyridine nucleotide metabolic process'.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is provided in a DOC file format, which may not be ideal for direct computational analysis.
