Title: The effect of ultrasound on genetic instability in diploids of Aspergillus nidulans. Author: Houghton JA, O'Dowd J. Journal: Folia Microbiol (Praha); 1979; 24(5):385-8. PubMed ID: 393595. 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.[Abstract] [Full Text] [Related] [New Search]
