Figure 5.
Protein-protein interaction networks of four overrepresented transcription factor families (AP2/ERF, MYB, bHLH, and C2H2) in S. caninervis. Different node colors indicate different TF family genes, and each edge indicates an interaction between two proteins. Red, yellow, green, and blue nodes mark AP2/ERF, MYB, C2H2, and bHLH TF families, respectively. The number of interacting genes was indicated by cycle size.
