Changes in the Bifurcation Diagrams of Figure 3 Due to Changing Parameter Values

<p>The black lines indicate the standard parameter values, the blue lines a lower value, and the red lines a higher value for the corresponding parameter.</p

Bifurcation Diagrams of the Extended Models Showing Transgene Induced Silencing

<p>Solid lines indicate stable equilibria; dashed lines unstable equilibria; open circles Hopf bifurcations; and closed circles fold bifurcations. The dynamic behaviors in regions I, II, and III are shown in <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.0010021#pcbi-0010021-g004" target="_blank">Figure 4</a>.</p
