Antisense RNA that affects Rhodopseudomonas palustris quorum-sensingsignal receptor expression

Quorum sensing in the bacterium Rhodopseudomonas palustris involves the RpaI signal synthase, which produces p-coumaroyl-homoserine lactone (pC-HSL) and RpaR, which is a pC-HSL–dependent transcriptional activator. There is also an antisense rpaR transcript (asrpaR) of unknown function. Recent RNAseq studies have revealed that bacterial antisense RNAs are abundant, but little is known about the function of these molecules.
