Abstract:
Six aggregation-defective mutants of Polysphondylium violaceum dependent on external addition of the pheromone D factor for aggregation were isolated after nitrosoguanidine mutagenesis. With a screening technique based on synergistic development, D-factor-dependent mutants can be separated from other kinds of aggregateless mutants. Genetic complementation analyses of the newly isolated mutants showed them to be mutant at the aggA locus. Individual mutants exhibited different sensitivities to D factor(s), responding maximally over a 300-fold range of concentrations.
