Figure 1

The three parallel quorum-sensing (QS) signaling pathways of Vibrio harveyi. The three types of QS signals (AHL, AI-2, and CAI-1) as well as the regulatory process are described below in the text. Legends: sRNAs stands for bacterial small RNAs. The circles linked to LuxN, LuxQ, CqsS, LuxU, and LuxO indicate the phosphorylation status of the proteins (P, phosphorylated; no letter, dephosphorylated). Bold arrows symbolize genes; thin arrows represent RNAs, either sRNAs or mRNAs. Red lines indicate nontranscribed RNAs; green lines, transcribed RNAs. Figure is adapted from [48].
