Extraction and Purification of DNA from Wood at Various Stages of Decay for Metabarcoding of Wood-Associated Fungi

Assessment of endophytic and saprotrophic microbial communities from wood-extracted DNA presents challenges due to the presence of surface microbes that contaminate samples and plant compounds that act as inhibiting agents. Here, we describe a method for decontaminating, sampling, and processing wood at various stages of decay for high-throughput extraction and purification of DNA.
