Differential expression and co-expression network analysis of MTs and PCSs under varying Cd abundances. (A-D) Differential expression profiling (A, C) and co-expression network analysis (B, D) of MTs (A, B) and PCSs (C, D) in the shoots and roots of rapeseed plants under high Cd and low Cd conditions. In the heat maps, the upward and downward arrows indicate the upregulation and downregulation of differentially expressed genes. In the gene co-expression networks, cycle nodes represent genes, and the size of the nodes represents the power of the interrelation among the nodes by degree value. Edges between two nodes represent interactions between genes. Mock means the Cd-free condition
