Abstract
Sequences of the internal transcribed spacer (ITS) region of the nuclear ribosomal DNA of ectomycorrhizal fungi were analysed and a specific PCR primer pair for Tricholoma matsutake was designed. Using the primer pair, part of the ITS region of T. matsutake (400 bp) was amplified, but no amplified fragment was detected for other ectomycorrhizal fungi. PCR was performed on DNA extracted from mycorrhizas of T. matsutake and Shiro soil (extramatrical mycelium of T. matsutake and soil complexes) and the 400 bp fragments were also specifically amplified. This indicates that presence of T. matsutake at any of its life stages can be easily confirmed by PCR typing.
