鵝膏菌屬真菌RAPD分析及親緣關系的研究

陳作紅　張志光　張天曉

摘要：本文對采自湖南莽山的26種鵝膏菌屬（Amanita）真菌進行了隨機擴增多態性DNA （RAPD）分析，40個隨機引物中篩選出擴增效果較好的6個引物，每個引物能產生1～10條DNA條帶，獲得的RAPD譜帶清晰并呈現多態性OPG15、OPH04兩個引物擴增的RAPD譜帶能將26種鵝膏菌完全區分開來，通過6個引物的RAPD分析獲得的平均相似性系數表明種與種之間的相關系數在20D60%之間，平均鏈鎖聚類分析可將26種鵝膏菌分為二大類，且一些具菌環和苞狀菌托的種類聚在一起，與形態分類基本相吻合。

ABSTRACT: Random amplified polymorphic DNA (RAPD) was used in analysing the relationship among twenty-six speices of Amanita from Mangshan, Hunan. Of 40 primers, 6 ones generated reproducible RAPD profiles, and each one produced 1-10 bands. Two primers (OPG15 and OPH04) could differentiate 26 species of Amanita by its RAPD profiles. The similarity coefficients obtained from profiles generated by six primers among Amanita were about 20-60%. A dendrogram was constructed using average linkage clustering for clustering analysis. It indicated that there were two groups in 26 species and some species with ring and membranous volva clustered a group which coincided with morphological classification.

KEY WORDS: Amanita, RAPD, Relationship
