Fig 3. Gene ontology (GO) annotations of differentially expressed genes (DEG) in symbiont-colonized P. vulgaris roots.

GO term annotation of (A) upregulated and (B) downregulated DEGs in mycorrhized roots. GO term annotation of (C) upregulated and (D) downregulated DEGs in nodulated roots. The DEGs were summarized in three main GO categories, biological process, molecular function and cellular component. The analysis was performed using classification Super Viewer tool at The Bio-Analytic Resource (BAR) for Plant Biology (http://bar.utoronto.ca) and the values of normed frequency was used to plot the graphs. The y-axis indicates the sub-categories and the x-axis indicates the frequency of a sub-category of genes in that category.
