Abstract

Interspecific hybrids produced by polyethylene glycol induced fusion of protoplasts from auxotrophic mutants of Aspergillus nidulans and Aspergillus rugulosus were grown in the presence of the recombinogens benomyl and chloral hydrate to stimulate segregation. The A. nidulans parental strains used had a known genetic marker in each linkage group. Hybrids grown on complete medium containing benomyl yielded more segregants. Analysis of the segregants showed that the distribution of A. nidulans linkage groups was random. No specific linkage group appeared in all the segregants. The two parents are closely related taxonomically and the findings from these experiments suggest that a high degree of chromosomal homology may exist between them.
