Spheroplast fusion and heterokaryon formation in Mucor racemosus.

Abstract:

:Heterokaryons of Mucor racemosus were produced by fusion of spheroplasts from two auxotrophic strains of the fungus. Germinated sporangiospores were converted to spheroplasts by using commercial chitinase and Myxobacter AL-1 chitosanase. Spheroplasts from the auxotrophic strains were mixed in a buffered Ca(NO3)2 solution and fusion occurred. After cell wall regeneration, prototrophs were isolated. The frequency of heterokaryon formation was 1.45 X 10(-4). Prototrophic isolates segregated parental nuclei at a high frequency, indicating that heterokaryons had formed.
