雪峰虫草Ophiocordyceps xuefengensis为近年来发现的真菌新物种,它是生长在活体植物大青的根或者茎中的疖蝙蛾幼虫体上的寄生菌。本文报道了从天然雪峰虫草子座中分离获得菌株,从培养性状、形态特征、分子证据(ITS序列)等方面对该菌株进行了鉴定并确证为雪峰虫草的无性型。PCR检测表明该菌株含有MAT1-2交配型基因,但不含MAT1-1交配型基因。我们成功培育了雪峰虫草子座。
Cordyceps militaris Ophiocordyceps xuefengensis is a new fungus species discovered in recent years. It is a parasitic bacterium that grows on the moth larvae in the roots or stems of living plants. In this paper, the strain isolated from the natural snow peak Cordyceps was isolated from the traits, morphological characteristics, molecular evidence (ITS sequence) and other aspects of the strain were identified and confirmed as Xuefeng Cordyceps anamorph. PCR test showed that the strain contains the MAT1-2 mating type gene but does not contain the MAT1-1 mating type gene. We have successfully cultivated Xuefeng Cordyceps.
