Top GO (Gene Ontology) categories enriched among unigenes differentially expressed between MPG and PT6 (DEGs). Red and blue bars represent GO categories enriched among upregulated or downregulated DEGs, respectively, as compared to all unigenes subjected to DEG analysis. x-axis: top GO categories (log2[Significant/Expected] >1; P < 0.01) of differentially expressed genes (q < 0.0001). y-axis: log2 of number of annotated genes (Significant) vs. expected number of annotated genes (Expected) in each GO category listed
