Fig. 1

Significantly and differentially expressed genes identified within each group. The figure contains the heat map representation of the genes, which were significantly and differentially expressed in response gene deletion, changing copper levels, or their additive effect, or their interactive effect. Colour key from blue to red indicates the low to high level of expression, respectively. These genes were further grouped according to the change in the direction of expression level. The number of the genes, which were identified to be up- or down-regulated in response to gene deletion effect or high copper levels were shown next to each group. Similarly, the number of the genes within each subgroup of G3, which compose of the genes significantly and differently expressed both in response to the gene deletion and copper level and the number of the genes within each cluster of G4, which compose of the genes significantly and differently expressed both in response to the interaction effect of gene deletion and copper level were represented next to each subgroup and cluster
