Abstract
A simple method was established to prepare DNA from fungal mycelia cultured on an agar plate. The fungi tested successfully with this method contained Zygomycetes, Ascomycetes, Basidiomycetes, and Oomycetes. This method did not require any time-consuming steps to crush or digest mycelia or fractionation in a phenol–chloroform mixture. The DNA was easily extracted by immersing and dispersing the mycelial plugs in a specific buffer (200 mM Tris-HCl, 50 mM ethylenediaminetetraacetic acid, 200 mM NaCl, 1% n-lauroylsarcosine, pH 8.0), then concentrated by ethanol precipitation. The total time to complete the whole procedure was less than 1 h. The quality and quantity were sufficient for polymerase chain reaction amplification and Southern blot analysis.
