摘要: 以1株野生平菇菌株为研究对象,采用ITS序列对其进行了种属鉴定,进一步通过单孢分离法获得了孢子单核菌株,经标准测交法和核迁移试验等对该平菇的交配型进行鉴定。结果表明,该野生平菇经ITS序列鉴定为糙皮侧耳,获得的69株孢子单核菌株,通过交配型鉴定得到T1型20株、T2型37株、T3型9株、T4型3株,通过核迁移试验鉴定T1、T2、T3和T4的交配型分别为A1B1、A2B2、A1B2和A2B1,属于四极性异宗结合真菌,χ2检测出现偏分离现象。

Abstract: A strain of wild oyster mushroom was identified by ITS sequence analysis.The mating type of the wild strain was accurately identified by single spore isolation,standard cross test and nuclear migration test.The results showed that the wild oyster mushroom was identified as Pleurotus ostreatus.The 69 monokaryon strains obtained were identified as T1(20 strains),T2(37 strains),T3(9 strains)and T4(3 strains)by mating type identification.The mating types of T1,T2,T3 and T4 were identified as A1B1,A2B2,A1B2 and A2B1 respectively by nuclear migration test.It was proved that the wild oyster mushroom was a quaternary heterozygous combination fungus.The χ2 test showed segregation distortion rule.
