The GacS, SalA, and RetS regulatory networks in P. syringae B728a impacted diverse traits in an environmental signal-dependent manner. The regulators examined in this study are shown in blue type, regulated genes or traits are in black type, and relevant environmental signals are in red t ype. Not all traits identified in these networks are shown, and the arrows may indicate direct or indirect regulation. RpoN contributed to the coactivation or corepression of traits, as indicated. RpoN* indicates a contribution of RpoN to positive regulation in epiphytic sites and the in vitro treatments and to weaker positive regulation or even negative regulation in the apoplast. 2°, secondary.
