Antibiotic resistance to G418 has been transferred into Chinese hamster cell lines via a plasmid vector. The same plasmid, which also contained the Leu2 gene, has been used to transform Leu2- yeast (strain MC16) to leucine prototrophy. Subsequent fusion between transformed yeast and untransformed hamster cells demonstrated that plasmid DNA could be transferred and its genes expressed within the mammalian cell genome. The fusion of transformed hamster cells with untransformed MC16 yeast cells demonstrated that DNA integrated within the mammalian cell genome could be transferred to correct the Leu2 deficiency and also confer G418 resistance on some yeast colonies.

The expression of foreign proteins in the fission yeast, Schizosaccharomyces pombe, is achieved by introducing an expression vector along with a transducing vector containing an autonomously replicating sequence. We created the expression vector pCMV-Leu2, carrying the LEU2 gene, which complements S. pombeleu1-32, and the transducing vector pUCA-Neo, containing a neomycin-resistance gene. Transformants were screened on leucine-deficient solid medium, followed by rescreening on G418-containing medium. Most of the surviving clones in the initial auxotrophic screening were found to be G418 resistant. The utilization of the pCMV-Leu2 and pUCA-Neo plasmid combination may facilitate rapid screening of S. pombe transformants.
