芥黄蜜环菌交配型复等位基因的研究

Diversity of Mating Alleles in Armillaria sinapina from Northeast China

从大兴安岭长白山采集１７号芥黄蜜环菌，用分离的单孢菌株进行交配型测定，证实中国该种为双因子异宗配合机制，选取各号标本的４种交配型菌株进行循环配对实验，结果发现该种的交配型基因座的多样性很高，共有１３对复等位基因，证明该种在世界分布区域内具有较强的生态适应能力。

The diversity of mating alleles in population of Armillaria sinapina in Great Xingan & Changbai Mountains were inverstigated.The results from mating tests between the four haploid strains which represented a fruiting body’s mating genotype and another one were used to deduced mating genotypes among closely adjacent individuals.13 pair mating factors have been found from the 17 stocks except four individuals from the same location (about twenty kilometers apart) sharing one mating genotype.The result indicated that the fungus possessed high level of mating alleles diversity and adapting ability in this area.
