A stable amicronucleate strain of Tetrahymena thermophila was isolated following nitrosoguanidine mutagenesis. The mutant has the same growth rate and viability as the micronucleate parent strain, and has no micronucleus detectable by chromatin-specific staining in vegetative growth or during conjugation. The mutant pairs with normal efficiency with cells of complementary mating type. Matings of the mutant with aneuploid strains which lose their micronucleus during meiosis produced cell pairs… CONTINUE READING
