Production of secondary metabolites is tightly regulated by transcriptional regulators in Streptomyces. Many regulators have been identified by gene disruption in Streptomyces; however, there are still unknown regulatory genes yet to be revealed due to gene silence under laboratory culture conditions. In present study, a T7 expression system was used to identify novel regulators by gene deletion and constitutive-expression of nine candidates. We reported that the constitutive-expression of a MarR family transcriptional regulator MapR (SCO2398) resulted in i
