aThe numbers of homologs were determined by blastp searches (with default values for the parameters).

bThe number of cheA homologs in the genomes of G. met. and G. ura. includes a contribution from one cheAY fusion.

cThe numbers are cheY genes in the major clusters. Numbers in parentheses also includes genes that encode for singleton CheY-like receiver domain proteins.

dChemotaxis gene clusters are defined to contain three or more che genes.
