PPI network construction and Module analysis of the DEGs at day 4. A The PPI network of the DEGs consisted of 141 nodes and 356 edges. B The most significant module consisted of 15 nodes and 50 edges extracted from PPI network (MCODE score = 7.143). C The second significant module consisted of 13 nodes and 38 edges extracted from PPI network (MCODE score = 6.333). The nodes represent proteins, and the edges between nodes represent interactions. The greater the degree of correlation, the larger the diameter of nodes. The nodes are red for upregulated DEGs, and blue for downregulated DEGs. PPI protein–protein interaction, DEGs different expression genes
