Tn 1000 (γδ) insertions stabilize pBR322-derived recombinant plasmids in Escherichia coli

Tn1000 (or 'γδ') insertions in a pBR322-recombinant plasmid carrying the threonine operon (pBE) were obtained either spontaneously during chemostat cultivation (pBE-2) or selected during transconjugation (pBE-3 and pBE-4). The different insertion derivatives were tested for their stability...
