Figure 3.
Hierarchical clustering and function enrichment analysis of 1716 differentially expressed isoforms among three stages. (A) Differentially expressed isoforms were clustered into four clusters: 359 isoforms in cluster I (with expression values as F1–9 > IM > F12), 460 isoforms in cluster II (F12 > F1–9 > IM), 401 isoforms in cluster III (IM > F1–9 > F12), and 526 isoforms in cluster IV (the others). Genes expressed higher than average are colored in red while lower in blue. (B) A list of enriched GO terms for genes in Cluster III. Red bars represent ratio of total annotated genes for each function, blue bars for differentially expressed genes within cluster III.
