Transformation of Podospora anserina with a dominant resistance gene

Summary The Podospora anserina immortal mutant incoloris, vivax was transformed to benomyl resistance with a -tubuline gene from a resistant Neurospora crassa strain. The transforming plasmid was integrated into the genome of the transformants, and subsequent Southern analysis and retransformation experiments provided no evidence for autonomous replication. Non-homologous integration was demonstrated in some of the transformants. Resistance to benomyl varied widely among the transformants and was conserved after the transformants were grown on non-selective medium.
