title: Isolation and characterization of plasmids from Micromonospora zionensis and Micromonospora rosaria.
abstract: Three plasmids from Micromonospora species were isolated and characterized. Micromonospora zionensis NRRL5466 (a producer of sisomicin and G-52) carried a high-copy-number plasmid pMZ1 (9.9 kb). Micromonospora rosaria NRRL3718 (a producer of rosamicin) contained a large plasmid, pMR1 (53.5 kb), and a relatively small plasmid, pMR2 (11.0 kb).
