Figure 3. Gene ontology enrichment identified in the Verticillium-infected Nicotiana benthamiana transcriptome by the BiNGO software. The gene ontology term enrichment analysis was performed on the 1,267 genes that displayed 10-fold induction at 16 d post inoculation when compared with the standard gene ontology term representation of Arabidopsis genes. Circle sizes indicate the relative number of genes that represent a gene ontology term, and the color gradient indicates the statistical robustness of the over-representation.
