Species-specific oligonucleotide primers for detecting wood rot fungi, Gloeophyllum trabeum, Trametes versicolor, Coniophora puteana, and Serpula lacrymans, and the primer detecting a group of related fungi to G. sepiarium were developed. These primer sequences were picked up from the internal transcribed spacer region between small-subunit rDNA and large-subunit rDNA. The species selectivities of the developed primers were checked. Real-time polymerase chain reaction (PCR) was carried out using these highly specific primers to quantitatively detect at least of 0.01 ng genome DNA of the target species. This quantitative PCR was also used to differentiate the target species DNA from mixed species DNA. A PCR-based technique using the species-specific primers would be applicable to multiple-sample assay in diagnosis of wood decay and to investigation of environmental fungal populations.
