Figure 2: Global view of clustered differential gene expression data.
From: The Transcriptional Landscape of the Photosynthetic Model Cyanobacterium Synechocystis sp. PCC6803
Hierarchical clustering was applied to 3064 Synechocystis genes based on expression data obtained for perturbations in environmental conditions. The dendrogram at the top displays the structure of clusters produced, while the molecular functions enriched among the genes of these clusters are shown below. Positive or negative expression contrasts with the respect to the corresponding reference samples are indicted by shades of red or green, respectively.
