Genetic analysis of a gene regulating the timing of developmental events in Dictyostelium discoideum.
In Dictyostelium discoideum, there exist genes which regulate the timing of developmental events. In one class of these rapidly developing (rde) mutants, the rate of development is accelerated, resulting in the formation of spores and stalk cells in about 2/3 of the time required for the parent. Linkage analysis of one of the rde strains, HTY506, demonstrated that rdeC1850, carried by the mutant is located on linkage group III. Therefore HTY506 differs genetically from the strain FR17, the first rde mutant described which carries a mutation rdeA1 on linkage group IV. While strain HTY506 has a pleiotropic phenotype, the altered characteristics of strain HTY506 appear to be caused by a single mutation, rdeC1850.
