Coix Transcriptome Analysis Under Cadmium Stress

Pengliang He published transcriptome data from a 2026 study on the medicinal plant Coix lacryma-jobi. The dataset includes gene expression profiles from roots, stems, leaves, and grains of the YY03-03 germplasm exposed to 0, 15, and 30 mg kg⁻¹ cadmium. It contains counts of differentially expressed genes (DEGs) and raw sequencing data, with up to 9.79 billion base pairs generated per sample.

Use Cases

• Identify candidate genes for cadmium tolerance based on differential expression patterns across plant tissues.
• Analyze pathways related to environmental adaptability and signal transduction mentioned in the KEGG analysis.
• Validate transcriptomic findings using the 12 stress-responsive DEGs assessed by qRT-PCR.
• Study the molecular basis for low cadmium absorption and translocation capacity in the YY03-03 coix variety.

Strengths

• Includes transcriptome data from four distinct plant tissues (roots, stems, leaves, grains) under control and cadmium-treated conditions.
• Quantifies differentially expressed genes (DEGs) with specific counts per tissue, e.g., 3818 DEGs in leaves.
• Sequencing depth is detailed, with up to 9.79 billion base pairs generated for some samples.
• Experimental design includes three cadmium concentration levels (0, 15, 30 mg kg⁻¹) for physiological measurements.

Limitations

• Row count and column-level documentation are unknown, requiring manual inspection after download.
• The dataset is small (287.6 KB), suggesting it may contain summary or processed results rather than raw sequencing reads.
• Geographic origin of the Coix germplasm and specific experimental time range are not provided.
