S, susceptible; R, resistant.
Mean diameters were obtained by measuring the zones of inhibition produced by 10 independent S. cerevisiae Leu+ transformants. The mean diameter for YKKB-13 transformed with YEp51 alone was 63 mm. The mean diameter for YKKB-13 transformed with a susceptible control was 43 mm. The mean diameter for YKKB-13 transformed with a resistant control was 0 mm.
P < 0.05.
