The P1B-ATPase subfamily is an important group involved in transporting heavy metals and has been extensively studied model plants, such as Arabidopsis thaliana Oryza sativa. Emerging evidence indicates that one homolog Glycine max also cadmium (Cd) stress, but the gene family not fully investigated soybean.Here, we identified 20 metal ATPase (HMA) members soybean genome, presented 10 paralogous pairs, which significantly greater than number or rice, was likely caused by latest whole genome duplication event soybean. A phylogenetic analysis divided into six groups, each having conserved divergent structures protein motif patterns. integration of RNA-sequencing qRT-PCR data from multiple tissues provided overall expression pattern for HMA Further comparisons patterns single nucleotide polymorphism distribution between pairs suggested functional conservation divergence genes during evolution. Finally, analyses HMAs expressed response to Cd stress on how plants manage tolerance, at least two contrasting genotypes examined.The genome-wide identification, chromosomal distribution, structures, evolutionary provide insight their potential involvement responses. These results will facilitate further research family, biological functions
