Abstract Polyamines play an important regulatory role during plant growth and development and adversity stress, and polyamine oxidase (PAO) is involved in polyamine catabolism. In this study, an up-regulated polyamine oxidase gene GmPAO1 was obtained by transcriptome sequencing analysis and screening at soybean seedling stages. Also, its expression pattern and function were analyzed. The identification results of transgenic GmPAO1 soybean positive lines showed that the relative expression level of GmPAO1 in the overexpressed lines was increased under salt stress. With increasing stress concentration, the seed germination rate decreased. However, the seed germination rate of the overexpressed lines was… More >
