Semantic similarity clustering of enriched GO terms associated to differentially expressed genes. The 611 enriched GO terms were clustered according to their semantic similarity using the method of Wang. Cluster 1: “Cellular aromatic compound metabolic process” including 75 GO terms; Cluster 2: “Organic acid metabolic process” (108 GO terms); Cluster 3: “Anatomical structure development” (83 GO terms); Cluster 4: “Response to organic substance” (42 GO terms); Cluster 5: “Organic substance metabolic process” (40 GO terms); Cluster 6: “Regulation of biological process” (99 GO terms); Cluster 7: “Transport” (41 GO terms); Cluster 8: “Cellular component organization” (36 GO terms); Cluster 9: “Cell cycle process” (87 GO terms). GO terms in each cluster are indicated in Additional file 5
