- a All methods used a threshold that excludes 95% of the test-native set.
- b Genes identified as foreign by the method in the given genome. Pmm has 209 coding genes in genome islands out of a total of 1713 coding genes, and Pmi has 246 coding genes in genome islands out of a total of 1810 coding genes, per Coleman et al. (2006). c The number of genes identified as foreign by the method that lie within a genome island. The expected number is that which would arise if the genes identified as foreign were distributed randomly throughout the genome. Asterisks indicate statistical significance to the level P < 0.001. Numbers without asterisks are not significant even to P < 0.05. d The fraction of total putative foreign genes identified by the method that lie within genome islands.
