Analysis of relative expression by qPCR of class 4 terminator. Graphic represents the analysis of the terminator wf_204 present in mC_30. Column “Terminator” shows the level of expression of the primer positioned upstream of the terminator and the column “Extern” represent the data of the primer positioned downstream of the terminator. Data are presented as means ± standard deviation of three independent experiments. Asterisk indicates a statistically significant difference in expression levels downstream of the terminator wf_204 in mC_30; *P < 0.05.
