Abstract

Spontaneous tetracycline-sensitive, transfer-deficient mutants of R100-1 were selected and analysed by genetic complementation tests and with the restriction endonuclease EcoR1. While some of the Tets Tra- mutants were caused by a single deletion event which removed the Tetr genes and extended into the neighbouring transfer genes, other mutants were the result of the deletion of the Tetr genes within Tn10 which was accompanied by an inversion of adjacent DNA sequences. A clustering of deletion and inversion endpoints occurred in the traA gene. Some of the transfer genes of R100-1 were assigned to EcoR1 fragments.
