Abstract

Two independent high efficiency ts amber suppressor strains have been isolated as derivatives of a well-characterized supD ts suppressor strain (Oeschger and Woods, 1976). The mutations which raise suppressor activity have been shown by Hfr mapping to be distinct from each other and the supD locus. One of the isolates provides up to 100% efficient suppressor activity at low temperatures.
