fusion of cytoplasts from seven mtps- mutants to the nucleated thioguanine-resistant va2-b derivative tg-6 has yielded numerous cybrid clones which grow in cap plus thioguanine , whereas almost no clones have resulted from the fusion of nucleated mtps- cells to tg-6 cells : these results suggest that the gene ( s ) coding for the phenotype of mtps- cells is localized in the cytoplasm ( mtdna ? ) .
