Coexpression network of transcripts involved in sporulation in G. lingzhi. a) Analysis of the module–trait association. The line color corresponds to the correlation coefficient between the module and the stage, the line weight corresponds to the P-value, circle size and color indicate the Pearson correlation between modules and is displayed according to the scale on the right panel. b) Correlation network analysis of the “brown” module. The gene coexpression network is a scale-free weighted gene network with multiple nodes connected to different nodes via edges. Each node represents a gene, and the size of node circle is positively correlated with the number of interacting genes. The hub genes are denoted in pink, the TF-coding genes are denoted in yellow, the meiosis-related genes are denoted in purple, and the other DEGs in this module are denoted in green.
