Coix Transcriptome Analysis Under Cadmium Stress with Gene Expression Data

Transcriptome sequencing generated between 6.28 and 9.79 billion base pairs across control and cadmium-treated root, stem, leaf, and grain tissues of the coix plant (Coix lacryma-jobi L.). The analysis identified 1144 to 3818 differentially expressed genes (DEGs) per tissue type, with functional enrichment pointing to catalytic activity, metabolic processes, and signal transduction pathways. This dataset, authored by Pengliang He and last updated in March 2026, provides a molecular basis for breeding low-cadmium coix varieties.

Use Cases

• Identify candidate genes for cadmium tolerance in coix based on differential expression profiles.
• Analyze gene ontology enrichment to understand biological processes affected by cadmium stress.
• Investigate KEGG pathways related to environmental adaptation and signal transduction under metal stress.
• Validate transcriptomic findings using the 12 stress-responsive DEGs mentioned for qRT-PCR assessment.

Strengths

• Includes transcriptome data from four distinct plant tissues (roots, stems, leaves, grains) under control and treated conditions.
• Quantifies differential gene expression with specific counts, such as 3818 DEGs identified in leaves.
• Experimental design includes three cadmium concentration levels (0, 15, and 30 mg kg⁻¹) for physiological measurements.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for specific analyses.
• The dataset's focus is on a single coix germplasm (YY03-03), limiting generalizability.
