✦ Synopsis
Two plasmids were constructed consisting of the E. coli vector pACYC184 and the cyanobacterial plasmid pUC1. These recombinants, designated pUC104 and pUC105, can be transformed to E. coli K12 as well as to the cyanobacterium Anacystis nidulans R2 and in both hosts they express their antibiotic markers. pUC104 and pUC105 differ with respect to the location and the orientation of the pACYC184 segment in pUC1. pUC104 was found to be stable under all circumstances. Transformation of pUC105 to A. nidulans R2 gave intact plasmids when chloramphenicol was the selective agent, but upon ampicillin selection a deletion derivative was produced identical to pUC1. Further characteristics of pUC104 and pUC105 are described and their usefulness as cloning vectors is discussed.
