The KIX domain, conserved among various nuclear and co-activator factors, acts as a binding site that interacts with other transcriptional activators co-activators, playing crucial role in gene expression regulation. In plants, the domain is involved plant hormone signaling, stress response regulation, cell cycle control, differentiation, indicating its potential relevance to crop productivity. This study aims identify characterize domains within soybean ( Glycine max L.) genome predict their improving conservation evolutionary history of were explored 59 species, confirming presence diverse plants. Specifically, 13 identified classified into four main groups, namely GmKIX8/9 , GmMED15 GmHAC GmRECQL through sequence alignment, structural analysis, phylogenetic tree construction. Association analysis was performed between haplotypes seed-related agronomic traits using re-sequencing data from core collection 422 accessions. results revealed correlations SNP variations observed GmKIX8-3 GmMED15-4 seed phenotypic traits. Additionally, transcriptome confirmed significant during early stages development. provides first characterization structural, expression, genomic haplotype, molecular features soybean, offering foundation for functional
