摘要:

采用ERIC-PCR 技术对12 株秀珍菇菌株的亲缘关系进行分析,并与拮抗实验和酯酶同工酶实验进行对比。结果表明:在12 株秀珍菇菌株中,ERIC-PCR 扩增出的条带清晰,重复性好,多态性高。PCR 产物大致在150~3500bp 范围内,各菌株扩增条带数在9~16 条之间。聚类分析表明,在79% 的分类水平上,12 个菌株聚成4 组。MY 灰和MY 白菌株亲缘关系较近,聚为第1 组;HZ845 为第2 组;HZ3、HZ5 和HZ 夏亲缘关系很近,聚为第3 组;LD1、GY16、GY18、GY163、SM、XY 秀1 亲缘关系很近,聚为第4 组。ERIC-PCR 聚类分析结果与拮抗实验和酯酶同工酶分析结果基本一致,验证了ERIC-PCR 技术的可靠性。

Abstract:

ERIC-PCR technique was used to analyze the phylogenetic relationships among 12 kinds of Pleurotus pulmonarius strains. The results indicated that the amplified product bands of ERIC-PCR were mainly distributed in a range from 150 to 3500 bp with good reproducibility and high polymorphism. The number of amplified bands varied from 9 to 16 for each strain. Cluster analysis revealed 79% similarity and 4 distinctive clusters among 12 strains. Based on the close phylogenetic relationship, MY Gray and MY White were designated as the first cluster, and HZ845 was designated as the second cluster, and the third cluster included HZ3, HZ5 and HZ Xia, and the fourth cluster included LD1, GY16, GY18, GY163, SM and XY-Xiu1. Meanwhile, the third cluster and the fourth cluster exhibited much closer phylogenetic relationship. The tested phylogenetic relationships among P. pulmonarius strains by ERIC-PCR were consistent with the results from antagonistic test and isozyme analysis of esterase. Therefore, ERIC-PCR is reliable in the identification of P. pulmonarius strains.

Key words: ERIC-PCR technique, antagonistic test, esterase isozyme, Pleurotus pulmonarius, phylogenetic relationship
