Abstract

Lepista nuda is a world-wide species which has and international reputation as a excellent edible species. In this study, we investigated the genetic variation and taxonomic relationship of L. nuda and other five Tricholomataceae species were analyzed by random amplied polymorphic DNA (RAPD). 15 kinds of random primers were used. The distance matrix was calculated using UPGMA and phyolgenetic relationship were inferred by neighnor-joining (NJ) method. Various bands of 100bp∼1600bp were observed in electrophoretic patterns of RAPD. Nei's genetic distance was calculated using a total of 228 DNA bands identified, and phylogenetic tree was made. The Nei's genetic variations of L. nuda, Lepista surdida, Collybia peronata, Collybia confluens, Lyophyllum cinerascens, Laccara laccata were 0∼21.3%, 21.2∼28.0%, 15.4∼23.0%, 14∼21.8%, 16.5∼34.6%, and 12.4∼27.4%, respectively The consistency index, the retention index and homoplasy index were 0.5217, 0.5769 and 0.5156, respectively. Also, two groups could be made by NJ tree. The genetic distance between L. nuda and C. confluens was closer than that between L. nuda and L. sordida.

민자주방망이버섯은 우수한 식용버섯으로 세계적으로 분포하고 있는 종이다. 민자주방망이버섯과 5가지 송이과버섯 종들의 유전적인 변이와 분류학적 관계를 RAPD에 의해 분석 하였다. RAPD에 15가지 random primer를 사용하였다. 버섯들의 유전적 거리는 UPCMA를 사용하여 측정하였고 계통유전학적 유연관계는 neighnor-joining (NJ) 방법을 사용하여 분석하였다. PCR에 의하여 증폭된 RAPD 절편들은 100bp에서 1600 bp이었다. Nei-Li의 유전적 거리는 228개의 DNA밴드를 사용하여 계산하였고 이를 바탕으로 계통유전학적 계통수를 만들었다. 민자주방망이버섯, 자주방망이버섯 아재비, 가랑잎애기버섯, 밀버섯, 만가닥버섯, 졸각버섯의 유전적 변이 는 각각 0∼21.3%, 21.2∼28.0%, 15.4∼23.0%, 14.0∼21.8%, 16,5∼34.6%, 12.4∼27.4%이였다. CI (Consistency index), RI (Retention index), HI (Homoplasy inedx)의 값은 각각 0.5217, 0.5769, 0.5156이었다. 또한 NJ tree로 두 그룹을 만들 수 있었다. 유전적 거리는 민자주방망이버섯과 자주방망이버섯아재비보다 민자주방망이버섯과 밀버섯이 더 가까웠다.
