Killer toxin production in Pichia acaciae is associated with linear DNA plasmids.

Current genetics - 1 Jul 1990

Worsham P L, Bolen P L

Abstract excerpt

We have identified a strain of the yeast Pichia acaciae which produces a "killer" toxin active against the yeast Debaryomyces tamarii. The killer phenotype was associated with the presence of two DNA plasmids, pPacl-1 (13.6 kilobase pairs) and pPacl-2 (7.3 kilobase pairs). P. acaciae strains, cured of these plasmids by irradiation with ultraviolet light, lacked killer activity and were sensitive to toxin produced...
