Abstract
Mutants that affect the meiotic process in yeast are reviewed with an emphasis on structural phenotypes. By-pass of the normal nutritional requirements for entrance into meiosis: spd 1, cdc 25, cdc 35. By-pass of the a/α control: rme, CPS, sca. Mutants with little or no meiotic DNA synthesis: Mei 1, −2, −3, spo 7, −8, −9, cdc 8, −21, cdc 4, spo 11. Mutants with meiotic DNA synthesis (possibly defective): spo 1, cdc 2, con 1, cdc 7, spo 10, pac, rad 6, con 2, −3. Mutant with defective or modified kinetic functions: cdc 5, −14, spo 2, −3, −4, −5, −12, −13.
