Wheat Salt-Responsive bHLH Transcription Factors and Target Genes

A genome-wide analysis of the Chinese Spring wheat reference genome identified five salt-responsive bHLH transcription factors and twelve predicted downstream target genes. Expression profiling was performed on shoots and roots from the moderately salt-tolerant cultivar BARI Gom-25 exposed to 100 mM NaCl. The dataset was authored by Esteri Viitanen and last updated on 2026-04-23.

Use Cases

• Identify candidate salt-responsive transcription factors in wheat based on the genome-wide analysis described.
• Analyze tissue-specific gene expression patterns under salt stress based on the RT-qPCR profiling of shoots and roots.
• Investigate predicted regulatory networks between bHLH factors and downstream targets like RLK, CLC, and TaAPY.
• Study potential mechanisms for ion homeostasis and stress signaling during salinity responses in wheat.

Strengths

• Identifies five specific salt-responsive bHLH transcription factors (TaMYC2-B, TaMYC2-D, FIT1, and two ORG2/bHLH38-like paralogs).
• Includes expression data from a specific experimental condition (100 mM NaCl) and tissue types (shoots and roots).
• Dataset is licensed under CC-BY-4.0, facilitating open reuse.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Functional validation of the identified regulatory relationships is noted as required, indicating the data is primarily predictive.
