Relative transcriptional levels of genes related to central metabolism for L-parental strain MG1655 and MDS42. Metabolic networks showing the relative transcriptional levels of genes related to the central metalbolism, mixed acid fermentation and L-threonine biosysnthetic pathways. The numbers are the relative ratio of the expression level of MDS42 as compared to that of MG1655.
