Relative gene expression of gerAA. Transcription level of gerAA relative to rpoB determined by qRT-PCR in B. licheniformis MW3, B. licheniformis NVH1032, B. licheniformis NVH 800, B. licheniformis NVH1112, and MW3∆gerAA complemented with gerA from the four abovementioned strains. The horizontal line in the box represents the median expression value, and the box encompasses 50% of the observations (first quartile (Q1) to third quartile (Q3)). The ends of the whisker are set at 1.5*IQR above the third quartile and 1.5*IQR below the first quartile.
