Nullisomic Tetrahymena: Eliminating Germinal Chromosomes

PETER J. BRUNS 1 and TRUDY E. B. BRUSSARD 1

1 Section of Genetics and Development, Cornell University, Ithaca, New York 14853

Germinal and somatic functions in Tetrahymena are performed separately by the micro- and macronuclei, respectively. Cells with haploid micronuclei were mated with diploids to yield monosomic progeny. These were induced to undergo a form of self-fertilization, generating cells lacking both copies of one or more of the five chromosomes in the micronucleus while still possessing a complete macronuclear genome.
