Maize ABF Gene Family: 18 Members Identified Across 9 Chromosomes

Zixu Guo performed a genome-wide analysis of the ABA-responsive element binding factor (ABF) gene family in maize. The study identified 18 ZmABF members distributed across 9 chromosomes and functionally validated ZmABF8 as a key regulator of drought tolerance. The dataset was last updated on 2026-05-21.

Use Cases

• Identify candidate genes for drought tolerance improvement based on expression profiles under stress.
• Analyze phylogenetic relationships and conserved domains within the ABF gene family.
• Study promoter cis-elements, such as ABRE and ARE motifs, for ABA-mediated regulation.
• Investigate protein-protein interaction networks involving ZmABFs and SnRK2 kinases.
• Validate gene function through overexpression experiments, as demonstrated for ZmABF8.

Strengths

• Identifies 18 specific ZmABF gene members.
• Provides phylogenetic classification into four distinct subgroups.
• Includes expression profiling under drought, cold, and heat stresses.
• Contains functional validation data for ZmABF8, showing improved drought tolerance.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The primary file format is DOCX, which may require conversion for computational analysis.
