Figure 1From: Constitutive and regulated expression vectors to construct polyphosphate deficient bacteriaBroad-host range constitutive (pS7PPX1) and regulated (pBADPPX1) expression vector maps to obtain polyP deficient bacteria. Source of yeast DNA and primers used in plasmid construction were described in Methods. A detail description of pMLBAD and pMLS7 plasmids can be found in reference [22].Back to article page
