| Research Abstract |
In this study, we constructed the genetic linkage map of the sporeless mutant of Pleurotus pulmonarius based on the DNA markers, and determined the locus of sporeless mutation. Moreover, we obtained the DNA markers which are very tightly linked to this locus. These results enable to carry out the efficient breeding of a sporeless mushrooms. In addition, we cloned the region related to this mutation, and based on the information of linkage map we determined the whole nucleotide sequences of this region. By the comparison of the sequences from mutant and wild type, we found the differences in several gene structures. In future, we will identify the gene that causes the sporeless mutation of this fungus by using the complementation test and so on.
