AbstractThe diversity of Amating type in wild strains of Lentinula edodeswas extensively analyzed to characterize and utilize them for developing new cultivars. One hundred twenty-three Amating type alleles, including 67 newly discovered alleles, were identified from 106 wild strains collected for the past four decades in Korea. Based on previous studies and current findings, a total of 130 Amating type alleles have been found, 124 of which were discovered from wild strains, indicating the hyper-variability of Amating type alleles of L. edodes. About half of the Amating type alleles in wild strains were found in more than two strains, whereas the other half of the alleles were found in only one strain. About 90% of Amating type combinations in dikaryotic wild strains showed a single occurrence. Geographically, diverse Amating type alleles were intensively located in the central region of the Korean peninsula, whereas only allele A17was observed throughout Korea. We also found the conservation of the TCCCAC motif in addition to the previously reported motifs, including ATTGT, ACAAT, and GCGGAG, in the intergenic regions of Amating loci. Sequence comparison among some alleles indicated that accumulated mutation and recombination would contribute to the diversification of Amating type alleles in L. edodes. Our data support the rapid evolution of Amating locus in L. edodes, and would help to understand the characteristics of Amating loci of wild strains in Korea and help to utilize them for developing new cultivars. |
