Expression pattern analysis of the gonad samples of M. lateralis. A The principal component analysis (PCA) score plot of the first two principal components for the 40 gonad samples using 18,074 genes. The red and blue arrows indicate the development of ovary and testis, respectively. B Weighted gene co-expression network analysis (WGCNA) of the 40 gonad transcriptomes. Modules of co-expressed genes (M1–M15) are labeled in unique colors, and unassigned genes are labeled in grey. C Overrepresentation analysis revealed that seven modules (M7, M15, M14, M11, M12, M13 and M6) were significantly (q-value < 0.1) enriched with DEGs
