Abstract

Five basidiocarps of Pholiota species have been collected from the areas of BubJu Temple for last two years, and identified to those of P. adiposa or Pholiota species. The taxonomy of these basidiocarps with the morphological aspects was compared with the analysis obtained from the polymorphisms of PCR-RAPD bands made after reacted with the random primers. The polymorphic variations were observed within the species of the basidiocarps, but not between genomic DNA's of the mycelia obtained and the basidiocarps. Several different bands made from the primers (28 and 36) in PCR-RAPD reactions were identified within the genus of Pholiota and speculated to be specific for the individual basidiocarp of P. adiposa collected. The primers employed here were considered to be very useful for distinguishing the individual isolates or basidiocarps collected from the fields. Also, the basidiospores were obtained from the sporeprints of the above basidiocarps as a simple agar and confirmed with observations of clamp connection under microscopes. The matings of them indicated the 'tetrapolar' type, being different from the 'bipolar' type reported by Japanese basidiocarps of P. adiposa or P. nameko. Based on our work, the edible fungi collected were speculated to be a new breeding resource for those of Pholiota commercialized in Japan.

1996년부터 속리산 법주사 주변과 그 외의 지역에서 Pholiota species 5종을 채집하여 Pholiota adiposa와 Pholiota species로 동정하였다. 이 버섯들을 다른 버섯들과 random primer에 의한 RAPD를 실시하여 형태적 분류와 연관시켜 본 결과, primer #28(1.5kb와 1.0kb 사이)에서 Pholiota adiposa와 Pholiota sp.의 공통밴드가 형성되었고, primer #36(750과 500bp 사이)와 OPD-18(760 bp)에서는 검은비늘버섯만의 특이적 밴드가 나타났다. 모균주와 이를 접종원으로 하여 수확한 자실체의 DNA에서는 동일한 모양의 다형적 밴드가 형성되었다. 또한 채집된 5종의 검은비늘버섯은 약간씩 다른 밴드적 차이를 나타내었다. 검은비늘버섯의 포자지문법을 통한 단포자분리에 의한 mating 결과 tetrapolar형을 관찰하였는데, 이는 Arita와 Mimura(1969)가 이미 P. adiposa와 P. nameko가 bipolar 형이라고 한 것과 다른 결과이다. 본 실험은 PCR-RAPD를 이용하여 하나의 버섯에서 얻은 담자포자의 단핵(monokaryon)과 이핵(dikaryon) 균사간의 차이를 보기 위한 기초실험이며, 또한 육종 계획에 대한 응용을 위한 실험이다.
