Genome-wide characterization of soybean P 1B -ATPases gene family provides functional implications in cadmium responses.

ABSTRACT:

Background

The P1B-ATPase subfamily is an important group involved in transporting heavy metals and has been extensively studied in model plants, such as Arabidopsis thaliana and Oryza sativa. Emerging evidence indicates that one homolog in Glycine max is also involved in cadmium (Cd) stress, but the gene family has not been fully investigated in soybean.

Results

Here, we identified 20 heavy metal ATPase (HMA) family members in the soybean genome, presented as 10 paralogous pairs, which is significantly greater than the number in Arabidopsis or rice, and was likely caused by the latest whole genome duplication event in soybean. A phylogenetic analysis divided the 20 members into six groups, each having conserved or divergent gene structures and protein motif patterns. The in
