A vector molecule for the efficient transformation of higher plants has been constructed with several features that make it efficient to use. It utilizes the trans acting functi...
Phage Mu-1 and a thermoinducible derivative, Mu-1 cts 62 were inserted into the broad host range R factor RP4. These hybrid plasmids were transferred by conjugation to a phytopa...
SUMMARY All R factors so far described can be transmitted to Escherichia coli. F-like R factors are transmissible to the Proteus group but not to the Pseudomonadaceae. Among, fi...
ABSTRACT We have developed a series of powerful and versatile conditional-replication, integration, and modular (CRIM) plasmids. CRIM plasmids can be replicated at medium or hig...
An R factor from Pseudomonas aeruginosa , which confers resistance to penicillins, kanamycin, and tetracycline, was studied in Escherichia coli K-12. The R factor could coexist ...
