Homokaryons were successfully recovered by regenerating protoplasts prepared from vegetative hyphae of field isolates ofRhizoctonia solani anastomosis group (AG) 8, the causal pathogen of bare-patch disease of cereals. A mating type incompatibility system, which is similar to that reported in AG 1 and AG 4, was demonstrated in AG 8. All homokaryons obtained in AG 8 were able to form tufts with their parent isolates and other heterokaryotic field isolates of AG 8 tested. Heterokaryons were readily recovered from tufts of pairing of certain homokaryon combinations. The synthesized heterokaryons formed tufts with both of the contributing homokaryons. The majority of hyphal tip cultures isolated from tufts resembled one of the contributing homokaryons. These nonheterokaryotic hyphae in tufts are attributed to transient heterokaryon effects.
