Fig. 1 Flooding stress treatment process in Glycine soja. Sampled by flooding treatment for 7 days.
Fig. 2 Scatter Plot and Volcano Plot for FPKM under G. Soja flooding treatment. (A) A Scatter Plot of log10 (FPKM) in control and flooding stress samples is shown. Most genes (dots) should follow the x=y line. Based on the x=y line, the upper red dot indicates up-regulation, the lower blue dot indicates down-regulation, and the gray dot indicates no expression difference. (B) Volcano Plot mean shows Fold-change versus significance for each gene between control and flooding stress. Visualize statistical significance (p-value) on the y-axis versus the magnitude of change (fold change) on the x-axis.
Fig. 3 Heatmap visualized expression patterns for DEGs with Log2FC<│2│ & FDR<0.05 under flooding stress at 7 days. Red means up-regulation and blue means down-regulation.
Fig. 4 Gene ontology (GO) analysis for differentially expressed genes flooding stress treatments. GO analysis is divided in to three categories: Biological process (BP), Cellular component (CC), and Molecular function (MF). (A) GO analysis results for up-regulated DEGs. (B) GO analysis results for down-regulated DEGs.
Fig. 5 Kyoto encyclopedia of genes and genomes (KEGG) pathway analysis for differentially expressed genes flooding stress treatments. The analysis results were divided into up-regulation and down-regulation.
Fig. 6 Results of qRT-PCR analysis of candidate DEGs that were differentially expressed under flooding stress in RNA-seq results. (A) Candidate DEGs showing the highest expression in flooding stress. (B) Candidate DEGs showing the lowest expression in flooding stress.
Fig. 7 Isoflavonoid biosynthesis pathway and related DEGs under flooding stress in Glycine soja. The expression of selected isoflavonoid biosynthesis pathway DEGs genes were upregulated by qRT-PCR analysis. The expression levels of isoflavonoid biosynthesis pathway in Glycine max described by Chen et al. (2016) were represented blue and red color box. The open circles indicated intermediates during isoflavonoid biosynthesis pathway. Blue box: Genes up-regulated by flooding stress in Glycine max. Red box: Genes down-regulated by flooding stress in Glycine max. Open circle 1: 2,7,4'-Trihydroxyisoflavanone, 2: Formononetin, 3: 2'-Hydroxyformononetin, 4: Vestitone, 5: 7,2'-Dihydroxy-4'-methoxy-isoflavanol.
