Summary of experimental results concerning the production of hemolytic activity, phospholipase C and cyclolipopeptides in different genetic backgrounds.

<p>: Presence; : Absence (early stationary growth phase in LB medium at C).</p

Hypothetic biological regulatory network of CLP production (with negative interactions) deduced from the Boolean model.

<p>Circles represent the proteins in the network and edges represent regulatory interaction (bold lines: known interactions, dotted lines: hypothetical interactions). Arrow headed edges represent positive regulatory interaction, and T-headed edges represent negative interaction. PlcC: phospholipase C; CLPs: cyclolipopeptides production; R: unknown regulator (with positive feedback).</p

The two minimal consistent Boolean networks with 3 components.

<p>The graphical conventions used to described the interaction graph of each network are as follows: normal arrows correspond to positive interactions, and T-end arrows correspond to negative interactions. Asynchronous state graphs are represented in a 3D-grid, with in the vertical axis (first component), in the horizontal axis (second component), and in the third axis (third component).</p
