Differentially-expressed biofilm-related genes.

<p>Genes previously shown to have roles in biofilm formation were broken into different functional categories as in Finkel and Mitchell [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0201969#pone.0201969.ref053" target="_blank">53</a>]. Genes up- or down-regulated in biofilms as compared to planktonic cells or in PAC-treated biofilms as compared to biofilms alone are indicated by arrows. Negative regulators of biofilm formation are indicated by asterisks (*). Genes indicated in bold are those with potentially unexpected expression changes compared to biofilms formed in serum-like conditions.
