NRAMP Gene Family in Wheat and Ancestral Species Under Cadmium Stress

106 NRAMP gene members identified across wheat and its five ancestral species, including 29 TaNRAMPs in common wheat. The dataset, created by Leilei Shao and last updated in May 2026, provides a systematic genome-wide analysis of this metal transporter family. Preliminary functional studies indicate TaNRAMP005 and TaNRAMP006 are upregulated under cadmium stress and enhance cadmium tolerance in yeast.

Use Cases

• Analyze evolutionary trajectories of metal transporter genes based on identified NRAMP members across ancestral genomes.
• Study gene expression patterns under abiotic stress based on tissue-specific expression and cadmium-induced upregulation data.
• Identify candidate genes for improving crop tolerance based on functional validation of TaNRAMP005 and TaNRAMP006 in yeast.
• Perform promoter analysis for stress response pathways based on GO annotations indicating hormone and abiotic stress involvement.

Strengths

• Identifies 106 specific NRAMP gene members across multiple species.
• Includes functional validation data for two key genes (TaNRAMP005 and TaNRAMP006) under cadmium stress.
• Provides evolutionary analysis detailing gene loss and expansion mechanisms like segmental duplication.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is very small (19.3 KB), indicating limited scope or summary-level data.
