Hierarchical clustering of genes differentially expressed in ccw12 Δ. The transcriptional response of the ccw12 Δ mutant was compared to transcriptomes of other cell wall mutants (gas1 Δ, fks1 Δ, mnn9 Δ and kre6 Δ) and cell wall stress conditions (Zymolyase and Congo Red) [15, 16]. Each column represents a different condition. Each row represents the ratio of expression for each gene as it is indicated in the colour scale. The clustering tree was built using MeV software from TIGR.
