Sexual recombination in a homothallic,antibiotic producing fungus

The presence of a perfect or sexual stage in the fungus Emericellopsis salmosynnemata has made possible an investigation of the effect of meiotic recombination on yields of antibiotic. While most of the fruiting bodies produced by this organism are the result of selffertilization, conclusive evidence of cross-fertilization and recombination between two mutants was obtained. Cross-fertilization occurred rarely.
