Wheat Salt-Responsive Transcription Factors and Target Genes from Genome-Wide Analysis

A 2026 study by Esteri Viitanen identifies five salt-responsive bHLH transcription factors and twelve predicted downstream target genes in the wheat genome. The research includes in silico promoter analysis, co-expression network analysis, and RT-qPCR expression profiling of shoots and roots from the cultivar BARI Gom-25 under salt stress. The dataset is a 455.7 KB PDF document shared under a CC-BY-4.0 license.

Use Cases

• Identify candidate genes for wheat salt tolerance improvement based on the described transcription factors and target genes.
• Analyze tissue-specific gene expression patterns under salt stress based on the RT-qPCR results for shoots and roots.
• Study transcriptional regulatory networks in plant stress responses based on the co-expression and promoter analyses described.

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).
• Provides a foundation for future mechanistic studies with twelve predicted downstream target genes, including RLK, CLC, and TaAPY.

Limitations

• Dataset is a 455.7 KB PDF; the underlying raw data (e.g., expression matrices, sequence files) is not directly provided.
• Row count and column-level documentation are unknown, limiting suitability assessment for direct computational analysis.
• Functional validation of the predicted regulatory relationships is noted as required, indicating preliminary findings.
