인공재배된 만가닥버섯(Hypsizygus mamoreus)과 잿빛 만가닥버섯(Lyophyllum decastes)을 ITS $I{cdot}IV$ 부위의 염기서열에 의해 종속간 유연관계 및 RAPD 다형성을 분석하였다. ITS $I{cdot}IV$영역부위 종속간 유연관계에서 Group1 (SPA 100, 101, 102)은 만가닥버섯에 속하였으며, Group2 (11균주) 잿빛만가닥버섯의 대조 분리군 11균주는 동일한 종으로 동정되었다. ITS결과 14개 균주 시 4개 그룹으로 분류되었으며, Cluster I과 Cluster II는 58%의 유사도를 Cluster III과 Cluster IV는 41%의 유사성을 보였다. 또한 인공 재배한 잿빛만가닥버섯의 종 다양성을 분석하기위해 RAPD를 수행한 결과 가장 수량이 양호하며 우량계통인 SPA 202는 잿빛만가닥버섯인 Lyophyllum decastes SPA 203과 그룹화 되었으며 75%의 유사성을 보여주었고, Lyophyllum decastes 공시균주인 SPA 103과 SPA 104의 유사성은 65%로 나타났다.
Phylogenetic relationships of Hypsizygus mamoreus and Lyophyllum decastes artificial cultivated using ITS sequences and RAPD polymorphism have been analyzed. Based on ITS region sequences of 14 strains, we could divide into 2 group as group1 to Hypsizygus mamoreus and the control isolated group2 to Lyophyllum decastes were identified as the same species. Restrict analysis of rDNA ITS region which was amplified by PCR, 14 collected strains could be classified into 4 clusters. There was approximately 58% genetic similarity between cluster I(SPA 100, 101, 102) and cluster II(SPA 200, 208 and SPA 201, 202), 41% between cluster III(SPA 104, 103, 203) and cluster IV(SPA 204, 206, 207, 205) by BLAST analysis. RAPD polymorphisms were used to analyze the species diversity of artificially cultivated Lyophyllum decastes SPA 202. As a result, similarity between SPA 202 and SPA 203 was 75%, at the same time, similarity between SPA 202 and Pleurotus eryngii SPA 103 and SPA 104 was 65%.
