Wheat ARM Gene Family: Identification, Expression, and Stress Response Analysis

Jingxu Li identified 32 Armadillo (ARM) repeat protein genes in wheat (Triticum aestivum) and compared them with genes from five other plant species. The dataset, last updated in April 2026, includes analyses of gene structure, phylogeny, and expression responses to biotic and abiotic stresses. Results suggest specific TaARM genes are involved in responses to powdery mildew, stripe rust, and low-temperature stress.

Use Cases

• Comparative phylogenetic analysis based on ARM gene sequences from six plant species.
• Studying gene family expansion mechanisms based on described polyploidy-driven segmental duplications.
• Identifying candidate genes for stress tolerance breeding based on RNA-seq and qRT-PCR expression profiles for powdery mildew, stripe rust, and cold stress.

Strengths

• Includes a defined count of ARM genes for six species, totaling 98 genes.
• Analyses are supported by multiple methods: gene structure, motif, phylogeny, cis-element, and RNA-seq/qRT-PCR validation.
• Specific stress-response roles are identified for genes like TaARM13, TaARM18, TaARM22, and TaARM26.

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred after download.
• The dataset is very small at 13.6 KB, indicating limited scope or summary-level data.
