^*Only genes that qualify as PHX in at least one of the two genomes are included. 

^† Values for genes that do not qualify as PHX are shown in parentheses. Minus signifies the gene does not have a homolog in this genome. 

^§ For genes carrying multiple homologs in the same genome, the E(g) values for the homologous genes are given in the next line(s).
