Figure 2From: Transcriptional responses to polycyclic aromatic hydrocarbon-induced stress in Arabidopsis thalianareveal the involvement of hormone and defense signaling pathways Gene and experiment clustering of phenanthrene microarray dataset. Hierarchical clusterings of genes and experiments, created from phenanthrene and published Arabidopsis microarray datasets. Values in the Color Key are log2(treated/control) microarray intensity values. Experiment codes are listed in Table 1, and the heatmap is detailed further in Additional File 6.Back to article page
