Hypothetical regulatory network for PCN biosynthesis in Pseudomonas chlororaphis HT66, The triangular arrowheads indicate a positive regulation, whereas the flat ones indicate a negative regulation. The proposed model shows the relationship between the rpeA/rpeB and psrA in relation to other known regulators. Finally, another important cascade must exist downstream of psrA. A to G, phzA to phzG genes; AHL, acyl-l-homoserine lactone
