Comparative transcriptome analysis reveals the complex response mechanisms of soybean leaves and roots to salt stress

The results of this study demonstrate that salt treatment significantly inhibits the growth of soybeans, leading to decreases in the contents of photosynthetic pigments and enhancement of antioxidant enzyme systems in the roots and leaves of soybean plants. As a result, ROS accumulate and MDA levels increase. In addition, the assimilation and transport of ions in soybeans were affected by salt stress. Transcriptome analysis showed that the phenylpropanoid biosynthesis pathway was significantly enriched in soybean roots and leaves under salt stress conditions. In addition, three genes, Glyma.17G230500, Glyma.11G003600 and Glyma.09G192800, were identified by WGCNA screening.
