Northern blot analysis of the mar-like operon and Sso2536 mRNAs. Total RNA was prepared from S. solfataricus cells grown in the presence of different aromatic aldehydes and harvested in exponential phase. Lane 1, untreated control cells; lane 2, cells grown in the presence of 0.35 mM cynnamaldehyde; lane 3, 1 mM veratrylaldehyde; lane 4, 1 mM benzaldehyde. The filters were probed with the Sso1352 (A), Sso2536 (B), and Sso7d (C) genes. (D) Structure of the mar-like operon. BldR and the putative drug efflux permease are encoded by Sso1352 and Sso1351, respectively, and are transcribed in a single polycistronic mRNA as indicated. The stop/start codons of the ORFs are underlined in the sequence. The putative ribosome binding site(s) upstream of the Sso1352 gene is in bold. nt, nucleotides.
