Figure 4. Confirmation of comparative proteome by semi-quantitative RT-PCR.

Figure 4

A: Spot distribution of the selected virulence related protein on gel of BM. Several protein spots with different MW and pI of omp25 were identified. B: Relative transcription of virulence related genes in BM and BMΔvirB. BM and BMΔvirB were firstly cultured in TSB to logarithmic phase and then transferred into GEM4.0 for 3 h. RNA was isolated and relative transcription of virulence related genes was quantified by normalization with 16S rRNA. These genes were transcribed at a lower level in BMΔvirB than in BM.
