Ultraviolet Sensitivity Gene of Escherichia coli B

Abstract
The UV sensitivity gene of E. coli B was introduced into a K-12 recipient by transduction with phage PI. The UVs gene of E. coli B is cotrans-ducible with the proC locus of K-12, is closely linked to tsx, is not linked to lacZ, and only rarely to purE. The transductants are mucoid, filamentous on irradiation and show plating-medium response. The order of markers is lacZ proC tsx UVs purE.
