摘要
福克斯，h.m.，伯顿，J，张，S-T。Peberdy, J. F. 1994。香菇商业品系间的交配型不亲和性。实验真菌学，18,95-102。香菇具有多等位基因的四极交配系统。从21株真菌中获得的单核分离株进行了配对，以调查从世界不同地区获得的一系列商业栽培菌株中存在的A和B因子的数量。17个商业种群鉴定出9个不同的A因子和10个不同的B因子，而中国的4个野生分离株鉴定出8个不同的A因子和B因子。3个A因子和2个B因子在商业菌株和野生菌株之间共享。此外，在同核原生质体再生体中，双核核的核型比例没有达到预期的1:1。B因子之间的重组并不罕见，当检测到它时，发现它发生在具有相同A和B因子的不同菌株中。
Mating-Type Incompatibility between Commercial Strains of Lentinula edodes
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.
