Expression patterns of the differentially expressed genes in the MSG and PSG of the wild type and the mutant. a Venn diagram of the differential expressed genes (DEGs) between the mid silk gland and posterior silk gland (b) Venn diagram of the DEGs between the wild type and the mutant in the same tissue. MSG, middle silk gland; PSG, posterior silk gland. c Heatmap and Hierarchical clustering of the differentially expressed genes. d KEGG enrichment pathways for genes that are nearly uniformly down-regulated in both the MSG and PSG of the mutant. e KEGG enrichment pathways for genes that are generally obviously upregulated in both the MSG and PSG of the mutant. Corrected p-value: p-value in hypergeometric test after correction. All pathways had Corrected p-value < 0.05
