Summary

Curing of the viruslike particles harbored by a strain of the yeast Yarrowia lipolytica was achieved by UV irradiation. The cured strain was found to be able to maintain the viruslike particles after their re-introduction by crossing or by cytoplasmic fusion. The involvement of a UV-induced mutation of a yeast maintenance gene seems therefore unlikely.
