Rapid Degradation of Hfq-Free RyhB in Yersinia pestis by PNPase Independent of Putative Ribonucleolytic Complexes
Figure 3
Expression levels of the pnp mRNA in multiple mutants of Y. pestis by using quantitative PCR. RNA samples were prepared from various mutants lacking Hfq and other ribonucleases grown to exponential phase in BHI medium. The relative abundance of the pnp mRNA was accessed by real-time PCR.
