Figure 5From: Genome-wide transcriptome analysis of the transition from primary to secondary stem development in Populus trichocarpaOver-represented gene ontology categories during stem development. Statistically over-represented GO categories based on each of the three main gene expression pattern clusters depicted in figure 4A. (A) Cluster 1 genes, (B) Cluster 2 genes, and (C) Cluster 3 genes. The circles are shaded based on significance level (yellow = FDR below 0.05), and the radius of each circle denotes the number of genes in each category.Back to article page
