| Abstract: | Fox, H. M., Burden, J., Chang, S-T., and Peberdy, J. F. 1994. Mating-type incompatibility between commercial strains of Lentinula edodes. Experimental Mycology 18, 95-102. Lentinula edodes has a multiallelic tetrapolar mating system. Matings between monokaryotic isolates obtained from 21 strains of the fungus were carried out to investigate the number of A and B factors present in a range of commercially cultivated strains obtained from different areas of the world. Seventeen commercial stocks were characterized and found to have 9 different A factors and 10 different B factors, while 4 wild isolates from China were found to have 8 different A and B factors. Three A and 2 B factors were shared between the commercial and wild strains. In addition, the expected 1:1 ratio of nuclear types of the dikaryon was not obtained for homokaryotic protoplast regenerants. Recombination between B factors was not uncommon and when detected it was found to occur in different strains having the same A and B factors. |
