Genome-Wide Analysis of Soybean Polyamine Oxidase Genes Reveals Their Roles in Flower Development and Response to Abiotic Stress.

ABSTRACT: Polyamine oxidase (PAO) is an important enzyme that functions in the catabolism of polyamines. While plant PAOs have been studied in several species, there is a lack of research on this gene family in soybean (Glycine max L.), one of the major food crops worldwide. Here, a genome-wide analysis identified 16 GmPAOs from the soybean genome, which were unevenly distributed in nine soybean chromosomes and were then phylogenetically classified into three groups. Collinearity analysis identified 17 duplicated gene pairs from the GmPAO family, and their Ka/Ks values were all less than one, indicating that the GmPAO family has undergone purifying selection during evolution. Analyses of the conserved motif and gene structure revealed the sequence differences among the Gm
