Genome-Wide Comparative Analysis of WRKY Gene Family Explores Insight Into the Evolution and Expression Divergence in the Genus <i>Triticum</i>.

ABSTRACT: Wheat (Triticum aestivum L.), a globally significant cereal crop, plays a crucial role in human nutrition and agricultural systems. Recent studies have extensively examined the role of transcription factors across various plant genomes. However, comprehensive comparative genomic analyses of the WRKY gene family across various diploid, tetraploid, and hexaploid wheat genomes remain limited. Here, we conducted a detailed analysis of the WRKY gene family in one diploid, two tetraploid, and five hexaploid wheat genomes, identifying a total of 1912 WRKY genes. Consistent with previous reports, the genes were classified into three groups according to their conserved domain and motif architectures. Phylogenetic reconstruction resolved clear clades, with Group II forming the largest and mos
