Abstract:

It is difficult to extract genomic DNA from Tremella fuciformis due to the disturbance of abundant
polysaccharides and proteins. In this paper, a method is reported to directly extract DNA from dried Tremella fuciformis
without spore separation or mycelium culture procedures which enables one to achieve high-quality DNA in a high yield for
RAPD (random amplified polymorphic DNA) analysis. The RAPD results indicated the presence of DNA polymorphisms
in the tested samples. The results of this study will contribute to DNA extraction and variety identification of dried Tremella
fuciformis in food analysis and detection.

Key words: dried Tremella fuciformis, DNA extraction, random amplified polymorphic (RAPD) DNA, variety identification
