Figure 3.

The most significant homology groups in the cross-species analysis of heat stress. The figure shows the 15 most significant significant homology groups from cross-species analysis of heat stress microarray data with homologs in at least four of the eight species. All of the 15 homology groups were up-regulated during heat stress. The heatmap shows the contribution from each individual experiment where higher intensity corresponds to a more significant p-value. White squares indicate the absence of a homologous gene while grey squares indicate the presence of homologs that have not been measured (e.g. missing one the microarray). The other columns in the figure corresponds to the Homologene accession number (Group), the false discovery rate (FDR), the chaperon class (Class) and a gene description (Annotation). Full results for all 37909 homology groups are available as Additional file 2.
