Figure 4. Hsp104 overexpression cures Sup35 ORD mutants.
[PSI+] strains expressing scrambled versions of SUP35, scrambled ORD mutants or wild-type SUP35 were transformed either with a plasmid expressing HSP104 from the ADH1 promoter (+) or an empty vector. After 3 days growth, transformed strains were spotted onto YPD to test for [PSI+].
