Confirmation of sRNA candidate expression by northern blot analysis. sRNA expression during growth in CDM and in THY medium. 0.4: exponential growth phase (OD₆₀₀ = 0.4); 0.8: transitional growth phase (OD₆₀₀ = 0.8); 1.2: stationary growth phase (OD₆₀₀ = 1.2). The probes were specific for the RNAs indicated on the right of each blot. For comparison, the approximate sizes of the sRNA candidates, as determined by 5′RACE analysis, are indicated on the far right.
