Validation of microarray results by qRT-PCR. (A) The bars represent the relative expression of selected genes when B. cereus was grown under swarming versus non-swarming condition. For qRT-PCR, values are mean numbers ± standard deviations. (B) The Pearson correlation comparing microarray and qRT-PCR results.
