Coix Transcriptome Analysis Under Cadmium Stress with 9,588 DEGs

Transcriptome sequencing generated between 6.28 and 9.79 billion base pairs across control and cadmium-treated coix plant tissues. The analysis identified 9,588 differentially expressed genes (DEGs) in roots, stems, leaves, and grains under cadmium stress, with up to 1,907 genes upregulated in leaves. Pengliang He published this dataset on figshare in March 2026 to provide a molecular basis for breeding low-cadmium coix varieties.

Use Cases

• Identify candidate genes for cadmium tolerance in coix based on differential expression patterns across four tissue types.
• Analyze gene ontology enrichment for biological processes like catalytic activity and metabolic processes under cadmium stress.
• Investigate KEGG pathways related to environmental adaptability and signal transduction altered by cadmium exposure.
• Validate transcriptomic data using quantitative real-time PCR results for 12 stress-responsive DEGs.

Strengths

• Includes transcriptome data for four distinct plant tissues (roots, stems, leaves, grains) under control and cadmium-treated conditions.
• Quantifies 9,588 differentially expressed genes with specific counts for up/down regulation per tissue.
• Provides physiological measurements (e.g., photosynthetic rate decreased by up to 37.6%) correlating with molecular data.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for specific analytical tasks.
• Data is from a single coix germplasm (YY03-03) under specific cadmium concentrations, limiting generalizability.
