Functional distribution of differently expressed genes (DEGs). (a) Functional distribution of DEGs according to the gene ontology (GO) database. The y-axis shows the GO functional categories, while the number of genes in each category is plotted on the x-axis. (b) Functional distribution of DEGs according to the KEGG pathway database. The y-axis shows the KEGG functional categories, while the number of genes in each category is plotted on the x-axis.
