Abstract

Tricholoma matsutake (TM=T. caligatum var. nauseoum) is, for an agricultural income earned by Forestry by-products, a very important mushroom in Korea. The mycelia isolated from the basidiocarps were compared with basidiocarps of TM by the random amplified polymorphisms of RAPD-DNA bands. The mycelia were confirmed to be originated from the basidiocarps of TM by cluster analyses of the DNA-bands made from RAPDs and Southern blotting with the band (0.75 kb) identified. The mycelia defined were observed to grow very slowly at the rate of 10 cm per month at $25^{\circ}C$ and also to be semi-transparent and submerged in on PDA. The method developed in this work was considered to be very useful for confirming the mycelia originated from the ectomycorrhizal mushrooms and also to be applied for the fungal mycelia isolated from the commercial useful mushrooms.

송이는 동양권 문화에서는 중요하며, 값비싼 버섯으로 알려져 있다. 채집된 송이의 자실체에 분리된 송이균사에서 추출된 DNA를 RAPD 방법을 통하여 비교하였다. 비교된 송이균사들은 각각 분리된 송이자실체에서 분리되었으며, PDA에서 성장이나 균총의 형태가 다른 것들을 취하여 비교하였다. 그런데, 이 실험을 통하여, PCR 조건에서 만들어진 RAPD-밴드를 집괴분석한 것을 비교하였으며, 또 다른 방법으로는 Southern blotting 통하여 확인하였다. 그결과, 두 방법에서 송이균사로 추정되는 균사를 확인하여, 이들의 균사에 대한 실험실내의 성장과 균총을 확인하였다. 균사의 성장은 매우 느리며 (10 cm per month), 균총은 반투명한 것이며, 현미경관찰하에 어떤 후막포자와 갈고리모양의 균사가 발견되지 않았다.
