Genetic control of the cell division cycle in yeast. Following a shift from the permissive to the restric- tive temperature. Hartwell Joseph Culotti and Brian Reidt DEPARTMENT OF GENETICS UNIVERSITY OF WASHINGTON SEATTLE Communicated by Boris Magasanik March 27 1970 Abstract. The execution points for these gene products were determined in synchrony experiments to be at approx.

The first page of the PDF of this article appears above. The mutants undergo several rounds of DNA replication and nuclear division at the restrictive temperature and hence become multinucleate. 98105 USA SUMMARY Temperature-sensitive mutations in seven genes cdc 2 6 7 9 13 14 and 15 of Saccharomyces cerevisiae confer a defect in nuclear division.

Time-lapse photomicroscopy has been utilized to detect temperature-sensitive yeast mutants that are defective in gene functions needed at specific stages of the cell-division cycle. The gene products that are defined by the cdc cistrons are essential for the completion of the cell cycle in haploids of a and a mating type and in aa diploid cells. An assay for cytokinesis in yeast was developed and the mutants were shown not to have completed this process.

1 nuclear division and cell separation in yeast are dependent upon prior DNA replication. See all Hide authors and affiliations. The same genes therefore control the cell cycle in each of these stages of the life cycle.

2 a cellular clock controls bud initiation and the running of this clock is independent of the other events in the cycle DNA replication nuclear division and cell separation. Genetic control of the cell-division cycle in yeast. Seven genes controlling nuclear division.

At the restrictive temperature these mutant strains develop multiple elongated buds that do not separate from the parent cell. Reid Mitotic cell division in eukaryotes is accomplished through a highly repro-ducible temporal sequence of events. Culotti J Hartwell LH.

From the behavior of mutant strains carrying lesions in cdc4 or in cdc8 or in both genes it is concluded that. Genes Controlling Bud Emergence and Cytokinesis L. Received 30 September 1970 and in revised form 10 March 1971 Temperature-sensitive mutations occurring m two unlinked complementation groups cdc4 and cdc8 are recessive and result in a defect in DNA replication at the restrictive temperature.
