  • a The ctc-lacZ fusion in the SPβ prophage is linked to the chloramphenicol (cat86) and erythromycin (erm) resistance genes.

  • b The integrative plasmid pWH25 contains a 2-kb EcoRI-SphI fragment, including the 3′ end of rsbX and 1.9 kb downstream of rsbX.

  • c The strain contains part of plasmid pGK30 inserted into the amyE locus of the chromosome via a double-crossover event, thus linking the transcriptional gsiB-gfp fusion to the chloramphenicol resistance gene (cat86).

  • d The arrow indicates the construction of the strain by transformation.
