P86 strains 4706-1CρO and 4706-1DρO were transformed with the indicated TRP1 and HIS3 plasmids, respectively, and the transformants were used as cytoduction recipients from the [URE3] strains 3310 and 4645-8CU. These first cytoductants were tested for growth and feeding on USA and then used as donors in a second cytoduction to wild type [ure-o] recipients (strains 3310S and 4645-8C). The resulting second cytoductants were then tested for feeding on USA. Plasmids used were pH218 (CEN HIS3 HSP104), pH219 (CEN TRP1 HSP104), pRS423 (2μm HIS3), pRS424 (2μm TRP1), pRS313 (CEN HIS3), pRS314 (CEN TRP1), pH220 (2 μm HIS3 HSP104), and pH221 (2μm TRP1 HSP104).
Values are numbers of colonies showing feeding/total number of colonies tested.
