you can cure your strain from psi+ by growing
them in the presence of guanidine hydrochloride.
Look at Yeast 4,159 (1988)
BTW, if I do not mind D.Burke did not state
that you cannot transform psi+ strains with a plasmid
which carries SUP4-O, the point was that you should not
use such a plasmid to estimate the efficiency of
your transformation procedure because it would be much lower
than that using YEp24 for example.
