Fig. 4. The relative mRNA expression levels of the ubiA (A) and CoQ2 (B) genes. Expression levels in the pCT74-gpd strain samples are defined as 1.0, and expression levels in the transgenic strain are displayed as the fold increase over the reference sample. a-e Different lower-case letters indicate a significant difference (p <0.05).
