Current research

 

(1)Culture of the medicinal fungus Sparassis crispa
We focused on the Physiological study of this important medicinal fungus Sparassis crispa. The medium and environmental conditions for this fungus has been optimizing now.
(2)Cloning and analysis of the Oswc-1 gene encoding a putative blue light photoreceptor from Ophiocordyceps sinensis
Light plays an important role during both sexual and asexual growth of Ophiocordyceps sinensis, one of the best known traditional Chinese medicines. In the present study, we cloned Oswc-1, the homologue of the blue-light photoreceptor Ncwc-1 of Neurospora crassa, from O. sinensis by Hi-tail PCR. The deduced amino acid sequence of Oswc-1 contains the similar function domains as NcWC-1 including transcriptional activation, LOV (Light, Oxygen, or Voltage), PAS (Per-Arnt-Sim) and Zinc Finger domains. Phylogenetic analysis based on fungal WC-1 supported OsWC-1 was a blue light receptor. The expression of Oswc-1 mRNA was up-regulated upon irradiation significantly.
(3)Artificial cultivation of some edible fungi.
