Figure 2From: Transcriptomic and proteomic analyses of Desulfovibrio vulgaris biofilms: Carbon and energy flow contribute to the distinct biofilm growth stateHierarchal clustering (a) and principal components analysis (b) of the nine samples from planktonic and biofilm (T2-T4 represent exponential-phase and T5-T9 represent stationary-phase) grown on lactate and sulfate for Desulfovibrio vulgaris. The samples are grouped based upon similarities in the expression patterns of all genes with significant changes.Back to article page
