The detection of chemically induced chromosomal malsegregation in Saccharomyces cerevisiae D61.M: a literature survey (1984-1990).
Our objective is to summarize the published data obtained with a recently developed tester strain suitable for the detection of chromosomal malsegregation in yeast. Results from 25 papers were reviewed in which numerical data for 111 chemicals tested in Saccharomyces cerevisiae D61.M are reported (a total of 316 independent tests; 279 acceptable, 37 not meeting our criteria). Of the 111 compounds analyzed 43 compounds are positive for chromosomal malsegregation, 56 compounds are negative and 12 compounds do not meet our criteria for acceptance (inconclusive). Of the 43 compounds judged positive 5 (acetone, acetonitrile, benzonitrile, ethylacetate and propionitrile) were only positive using a cold interruption protocol. Recommendations are made for standardization of methods and protocols for screening purposes. Finally, a comparison with in vitro tubulin assembly data using mammalian tubulin is presented.
