FIGURE 5 DEMs enrichment network diagram of biosynthesis of amino acids and flavonoid biosynthesis. (a) RM vs. RL, (b) RH vs. RL, (c) RH vs. RM. Note: RL- roots in low salinity soil, RM- roots in medium salinity soil, RH- roots in high salinity soil. - upregulated DEMs, - downregulated DEMs. The small nodes connected to the large node (KEGG pathway) are DEMs annotated to the pathway. The thickness of the line indicates the fold change.

FIGURE 6 Combined analysis of soil properties and DEMs in Melia azedarach roots. Green circles represent soil properties, and orange circles represent DEMs. The color of connecting lines indicates the correlation between nodes (red- positive correlation, blue- negative correlation).
