Abstract

An experimental system was developed for assessing the role ofhetgenes in heterokaryon formation inNeurosporain nature. Burned sugar cane segments planted in soil were infected using a mixture of mutant ascospores of two genotypes.Neurosporaramified in the cane and erupted as distinct pustules of conidia. When ascospores carried identicalhetalleles, the (macro) conidial pustules which formed were heterokaryotic. On the other hand, when ascospores carried dissimilarhetalleles, the pustules were homokaryotic. These results showed that stable heterokaryons between compatible strains can form in nature. When two strains are growing together on a natural substrate, heterozygosity athetloci serves to maintain their individuality.
