摘 要：采用PCR技術(shù),，以rDNA-ITS區(qū)為分子指標(biāo),，對臺灣蟲草Cordyceps formosana及其無性型黃山被毛孢Hirsutella huangshanensis進行測序和比較分析,，以進一步確定兩者的對應(yīng)關(guān)系,。結(jié)果表明：兩者的序列完全相同,，從而在分子水平上證明了黃山被毛孢是臺灣蟲草的無性階段,。系統(tǒng)進化樹顯示臺灣蟲草的無性型歸為被毛孢屬較為合理,。

Abstract: The genes of the 5.8S rRNA and the complete internal transcribed spacer (ITS) regions from Cordyceps formosana and Hirsutella huangshanensis were sequenced and compared. The results showed that Cordyceps formosana and Hirsutella huangshanensis had the same ITS1-5.8S-ITS2 nucleotide sequences, strongly supporting the fact that Cordyceps formosana was the teleomorph of Hirsutella huangshanensis. Molecular phylogenetic analysis demonstrated that the conidial state of C. formosana belonged to the genus Hirsutella.
Key words: Hirsutela huangshanensis, rDNA-ITS, entomopathogenic fungi
