Summary
A thermosensitive λ phage mutant was isolated which can grow at high temperature only in the presence of the λ x gene product supplied in trans. This mutation tn was mapped within the x region, and λ tn phage expressed the pRoR-OP operon only poorly at high temperature.
Effects of the tn mutation on expression of other operons were also examined and compared with those observed with cro 27 or some tof mutations.
