Fig. 5

Expression profile and transcriptional regulatory network in the green and yellow modules. a, d Scatterplots of gene significance versus module membership for the green/S0 (a) and yellow module/S2 (d), with correlations and p-value indicated. b, e Heat map of genes in the green (b) and yellow module (e). Red indicates high expression, blue indicates low expression. The color scale represents Z-score. c, f GO analysis of genes in the green (c) and yellow module (f). Each circle represents an enrichment category, and the size of the circle indicates the number of genes. Detailed enrichment results are shown in Table S4 and S5. g, h Top 20 associated KEGG pathways for the green (g) and yellow module (h). i, j Coexpression network of the green module (i) and yellow module (j). The ellipses of the outer circle represent the hub genes, the arrows in the inner circle represent transcription factors, and the small dots in the circles represent other coexpressed genes in each module. The relationships of all the genes are connected by lines, the line color represents the weight. The red ellipse /arrow/dot indicates up-regulated (log2(R/S) > 1) and the blue ellipse /arrow/dot indicates down-regulated in the resistance line (log2(R/S) < − 1) at two spectific stages (T0 for the green module and T2 for the yellow module)
