Genome-Wide Identification of the <i>BXL</i> Gene Family in Soybean and Expression Analysis Under Salt Stress.

ABSTRACT: β-D-xylosidases (BXLs) are pivotal enzymes in xylan degradation, playing essential roles in plant development and stress responses. In this study, we identified 29 GmBXL genes in soybean through homolog alignment. Phylogenetic analysis classified these genes into three groups, with Group III being legume-specific. The GmBXLs are unevenly distributed across 15 chromosomes, with their expansion driven by both tandem and segmental duplications. Conserved motif and domain analyses revealed functional conservation, particularly in family 3 of glycoside hydrolase domains. Promoter regions of GmBXLs are enriched with hormone-responsive and stress-related cis-elements, indicating their involvement in diverse biological processes.
