^aOperons are regulated by other response regulators or are not known to be regulated by a response regulator.

^bThree operons are activated by both ComA and Spo0A.

^cOne operon is repressed by both Spo0A and DegU.

^dEight operons are activated by both ComA and Spo0A.

^eOne operon is activated by both Spo0A and DegU.

^fEleven operons are activated by both ComA and Spo0A.

^gFour operons are activated by both Spo0A and DegU.

^hEleven operons are activated by both ComA and Spo0A.

ⁱThree operons are activated by both Spo0A and DegU.

^jEight operons are activated by both ComA and Spo0A.

^kTwo operons are activated by both Spo0A and DegU.
