Ability of WS types carrying DGC-activating mutations in Mws, Aws and Wsp to invade from rare isogenic DGC-activated mutant types lacking wss and/or pga. (a) WS mutants cannot invade isogenic populations with a deletion of pga, but rapidly invade populations without wss (b). (c) Invasion rate is greatest against WS mutants lacking both wss and pga. (d) Control experiment for invasion of isogenic WS*-GFP versus WS*, both with wss and pga intact. WS* for the dominant population represent strains with identical WS mutations in mwsR, awsR, awsX or wspF as those of the invading strain. Data are average values from four independent replicates, error bars represent ±1 s.d.
