As a globally significant economic crop, the seed size of soybean (<i>Glycine max</i> [L.] Merr.) is jointly regulated by internal genetic factors and external environmental signals. This study discovered that the GLN family proteins in soybean are similar to the KIX-PPD-MYC transcriptional repressor complex in Arabidopsis, potentially influencing seed size by regulating the expression of the downstream gene <i>GIF1</i>. Additionally, β-1,3-glucanase (βGlu) plays a crucial role in antifungal activity, cell composition, flower development, pollen development, abiotic resistance, seed germination, and maturation in soybean. Through a detailed analysis of the structure, chromosomal localization, phylogenetic relationships, and expression situations in different tissues at different stages of the soybean <i>GLN</i> gene family members, this research certifies a theoretical foundation for subsequent research on the biological functions of <i>GLN</i> genes in soybean. This research incorporated a comprehensive genomic identification and expression analysis of the <i>GLN</i> gene family in soybean. The results indicate that the 109 soybean <i>GLN</i> genes are unevenly distributed across soybean chromosomes and exhibit diverse expression patterns in different tissues, suggesting they may have distinct functions in soybean morphogenesis. GO enrichment analysis shows that the <i>GLN</i> gene family may participate in a variety of biological activities, cellular components, and molecular biological processes, particularly in catalytic activity, cellular components, and metabolic processes. These findings provide important information for comprehending the role of the <i>GLN</i> gene family in soybean and offer potential targets for molecular breeding of soybean.
