Each row indicates the number of species for which pathway information could be collected. The columns indicate the number of species that show significant clustering of the pathway. Results for unmerged data sets are given within brackets. For example, there are 35 pathways that are significantly clustered (using merged data) in exactly three out of five genomes.
