From: Gene expression profiling to characterize sediment toxicity – a pilot study using Caenorhabditis elegans whole genome microarrays

Figure 1

Hierarchical cluster analysis. Transcript profiles of 1331 C. elegans genes, which were found to be significantly differentially expressed as result of Elbe and/or Rhine sediment exposure (ANOVA, n = 5, p < 0.05, >1.4-fold change). The individual figures illustrate the relationship between the sediment samples to the reference (Danube sediment). (A) Principal components analysis, the first three components are included. (B) Condition tree demonstrating the relationship of the 15 individual replicates. (C) Hierarchical cluster analysis showing individual replicates (n = 5, left) and group averages (right). D – Danube sediment, E – Elbe sediment sample, R – Rhine sediment sample.
