Genetic Recombination in the Lignin-Degrading Basidiomycete Phanerochaete chrysosporium

ABSTRACT

Heterokaryons made from auxotrophic strains of the lignin-degrading basidiomycete Phanerochaete chrysosporium were induced to fruit. The isolation of wild-type and double-mutant phenotypes from these crosses indicated that genetic recombination had occurred. Cytological studies demonstrated that more than 90% of the basidiospores from the wild-type and auxotrophic strains and from forced heterokaryons were binucleate. Colonies of the wild-type strain of P. chrysosporium arising from single, predominantly uninucleate conidia were all capable of producing fruit bodies and basidiospores.
