title: A rapid and convenient screening technique for developmental pathway mutants of Saccharomyces cerevisiae.
abstract: A brief exposure to iodine vapour was used to screen for mutants of the yeast Saccharomyces cerevisiae affected in development. Besides obtaining a large number of asporogenous mutants, two novel mutations were identified that permitted germination of spores to occur in conditions (sporulation medium) in which the wild-type would not germinate. These two mutations were named gdr1 and gdr2 for germination derepressed. Both alter nutritional control of germination, but not the kinetics of germination in glucose-containing medium.
