Diversity of A mating type in Lentinula edodes has been assessed by analysis of A mating loci in 127 strains collected from East Asia. It was discovered that hypervariable sequence region with an approximate length of 1 kb in the A mating locus, spanning 5' region of HD2-intergenic region-5' region of HD1, could represent individual A mating type as evidenced by comprehensive mating analysis. The sequence analysis revealed 27 A mating type alleles from 96 cultivated strains and 48 alleles from 31 wild strains. Twelve of them commonly appeared, leaving 63 unique A mating type alleles. It was also revealed that only A few A mating type alleles such as A1, A4, A5, and A7 were prevalent in the cultivated strains, accounting for 62.5% of all A mating types. This implies preferred selection of certain A mating types in the process of strain development and suggests potential role of A mating genes in the expression of genes governing mushroom quality. Dominant expression of an A mating gene HD1 was observed from A1 mating locus, the most prevalent A allele, in A1-containing dikaryons. However, connections between HD1 expression and A1 preference in the cultivated strains remain to be verified. The A mating type was highly diverse in the wild strains. Thirty-six unique A alleles were discovered from relatively small and confined area of mountainous region in Korean peninsula. The number will further increase because no A allele has been recurrently observed in the wild strains and thus newly discovered strain will have good chances to contain new A allele. The high diversity in small area also suggests that the A mating locus has evolved rapidly and thus its diversity will further increase.
