Fruiting Body Formation from Regenerated Mycelium of Pleurotus ostreatus Protoplasts

Fruiting bodies were induced from mycelium regenerated from Pleurotus ostreatus protoplasts. Mycelia originated from protoplasts conformed to parental strain mycelia in morphology. Six strains selected at random from the dikaryotic regenerants were able to form normal fruiting bodies, yielding 18% more than the parent.
