RT-qPCR analysis of expressions of the esi gene and the seven epothilone ORFs in the ZE9, ZE9 ∆esi and ZE9 att::esi strains after 24, 48 and 60 h of incubation in CMO medium. The expression level of epoA in the ZE9 strain at 24 h of incubation was set to be 1. The error bars represent the standard deviation of three independent experiments. **P < 0.01 and *P < 0.05, respectively
