title: The effect of ultrasound on genetic instability in diploids of Aspergillus nidulans.
abstract: Ultrasonication at 20 kHz and intensity of 59 W/cm2 of a diploid strain of Aspergillus nidulans was ound to lead to a significant increase in haploidization of germinating conidiospores. In a preliminary study ultrasound was found not to have an effect on the rate of reverse mutation in conidiospore suspensions of auxotrophic mutants.
