西藏冬虫夏草无性型5.8S rDNA,ITS间区系统发育分析

Phylogenetic analysis based on 5.8S rDNA and ITS spacer of anamorph of Cordyceps sinensis from Tibet

    摘要
  • 摘要: 采用相对较低的培养温度(5~12℃),从西藏那曲当年产风干冬虫夏草Cordyceps sinensis(Berk.)Sacc.分离得到菌株C21,综合其菌丝形态学特征及5.8S rDNA和ITS间区的系统发育分析结果,证实菌株C21为冬虫夏草菌的无性型,即中国被毛孢(Hirsutella sinensis).

     

    Abstract: Strain C21 was isolated from well-preserved air-drying fruit body of Cordyceps sinensis,from Nagqu,Tibet.Morphological characteristics of strain C21 were found closely similar with Hirsutella sinensis,and 5.8S rDNA ITS of C21 shared over 99.6% similarity with those of C.sinensis CYQ011,C.sinensis LiT9704SI and C.sinensis LiT9807Sc.Based on these results,stain C21 was identified as anamorph of Cordyceps sinensis,namely Hirsutella sinensis.
