WGCNA analysis reveals the co-expression gene module associated with ustilaginoidin biosynthesis. a The correlation analysis between module eigengenes (MEs) and traits. Each module is composed of a group of genes with a similar gene expression pattern. The heatmap showed the module-trait relationship, in which the color intensity represents the strength of positive or negative correlation. A deeper red color indicates a stronger positive correlation, while a deeper blue color indicates a stronger negative correlation. b The gene co-expression network in the MEblue gene module. The nodes in the network represent individual genes, while edges denote connections between genes, reflecting their similarity in expression patterns. The colors of nodes correspond to gene expression status: pink and blue represent up-regulated and down-regulated genes, respectively. The underline genes on the nodes are annotated to encode putative transcription factors. UvPKS1: Polyketide synthase, UgsJ: Methyltransferase, UgsH: Hypothetical protein, UgsR1: Transcription initiation factor, UgsL: Laccase, UgsT: MFS multidrug transporter
