Summary
The cell division cycle gene CDC25 was replaced by various disrupted and deleted mutant copies. Mutants disrupted at a central position of the gene, or lacking 532 residues within the amono-terminal half of the gene product grow normally in glucose, but not in acetate media, and they fail to sporulate as homozygous diploids. Disruptions or deletions within the carboxy-terminal half are lethal, except for the deletion of the 38 carboxy-terminal residues, which are required for sporulation but not for growth in glucose or acetate media. It is concluded that distinct domains of the CDC25 gene product are involved in the control of mitosis and/or meiosis.
