Fig 1. Transposon mutagenesis identifies novel components of the Rgg-SHP quorum sensing circuit.

(A) Sixteen loci were identified according to our criteria (see text). Gene names and chromosomal location are indicated, with the replication origin (*) at twelve o’clock. Components of the QS circuit previously identified are indicated (†). (B) Fourteen unique insertions (arrowheads) mapped to pptAB, a predicted ABC transporter. pptAB were replaced with a cassette containing aphA3, which confers resistance to kanamycin.
