Fig. 3. The absence of Tgs1 causes increased silencing at telomeres. (A) Wild-type (AEY3595), tgs1
(AEY3591), tgs1-W178A (AEY3793), rap1-12 (AEY3590) and rap1-12 tgs1
(AEY3594) were grown on rich medium for 3 days. (B) Quantification of white and red-sectoring colonies from the strains used in A. Less sectoring is indicative of increased silencing of the telomeric ADE2 reporter gene.
