Figure 6.

Northern blots showing growth-dependent expression patterns of S. typhi npcRNA candidates that partially overlap with ORFs of protein-coding genes. Growth stages of S. typhi and E. coli. OD₆₀₀ values are indicated across the tops of the blots. OD₆₀₀ 0.3: lag phase-steady bacterial growth; OD₆₀₀ 0.7: log phase-exponential bacterial growth; and OD₆₀₀ 1.5: stationary growth phase. The npcRNA candidates and RNA lengths are indicated. As loading controls, a few examples of ethidium bromide-stained 5S rRNA are shown.
