Overview of functional annotation and network construction. (A) The number of gene sequences and annotation. (B) Gene numbers in different gene families. (C) Numbers of gene pairs as PCC changing. (D) Nodes number and scale-free model fit (R²) distribution as change of PCC. (E) Nodes number and scale-free model fit (R²) distribution in the negative co-expression network as change of PCC. (F) Edges and nodes statistics in the positive, negative co-expression network and PPI network.
