Abstract
|
|
|
Effects of incompatibility existing between intra-and interspecies in Pleurotus spp. on protoplast fusion, clamp formation of their fusants and fruitbody production were investigated.
Protoplast fusion between intra-and interspecies of the fungus was achieved by Poly ethylene glycol treatment. The fusion frequency between interspecies was a little higher than that of interspecies. Fusion frequency between interspecies was not correlated with their similarities based on isozyme patterns. In case of protoplast fusion between intra-and interspecies, the fusants from the compatible isolates produced normal fruit bodies, while those from the incompatible isolates did not produce clamp connections and fruit bodies except those of a few isolates presumed as mutants.
