Basidioma Development and Genetic Recombination of Somatic Hybrids with Compatible and Incompatible Strains by Protoplast Fusion in Genera Pleurotus (Fr.) P. Karst. and Ganoderma P. Karst.
RÉSUMÉ
Somatic hybrids of intercompatible and interincompatible strains were obtained by protoplast fusion. The fusion products between compatible strains, Pleurotus ostreatus and P. florida, formed heterokaryons, while fusants between incompatible strains such as P. cornucopiae + P. florida, P. ostreatus + Ganoderma applanatum, and P. florida + Ganoderma lucidum formed synkaryons that retained genes from both parents. The heterokaryons showed the same level of basidioma development. In contrast, the synkaryons showed unique characteristics including clamp connection formation at mitosis, either partner basidioma development, and abnormal segregation and recombination compared with intercompatible strains. Synkaryons can be classified into homokaryotic and heterokaryotic type.
