Fig. 3: The enriched KEGG pathways and diagram of arachidonic acid metabolism pathway evolution in the four desert rodents, Dipus sagitta (DS), Orientallactaga sibirica (OS), Meriones meridianus (MM), and Phodopus roborovskii (PR).

a The enriched KEGG pathways of combined positively selected genes (PSGs) and rapidly evolving genes (REGs) in the four desert rodents. The x axis shows the -Log (P-value) of PSGs and REGs in each pathway. The size of the dot indicates the number of genes. The depth of dot color indicates the enrich ratio. b Alterations in the arachidonic acid metabolism pathway of the four desert rodents. Genes in yellow background are PSGs, genes in violet background are REGs, and red genes are under convergent evolution. The symbol next to the gene indicates the species in which the gene has evolved.
