| 摘 要： | 通过对不同来源的桑黄菌株进行分子鉴定和遗传多样性分析,为后续桑黄种质资源的研究、开发及利用提供参考。采用rDNA ITS序列分析技术,对收集到的国内22个桑黄菌株进行分子鉴定与遗传多样性分析。依据rDNA ITS序列计算遗传距离并构建系统发育树,结果显示收集到的桑黄菌株明确聚为3个独立类群,且3个类群的桑黄真菌存在明显的遗传分化。通过BLAST分析,成功鉴定出3类桑黄种质分别为:桑树桑黄(Sanghuangporus sanghuang)、杨树桑黄(Fuscoporia gilva)及丁香桑黄(Inonotus baumii)。不同来源的桑黄菌株间具有一定的遗传多样性,种间遗传趋异度显著高于种内。本研究结果提供了一种准确可靠且简单易行的桑黄真菌分子鉴定技术,可明确各桑黄真菌的种属来源及遗传结构组成,为桑黄真菌的进一步研究及开发应用奠定了基础。 |

| Abstract: | To study the genetic diversity and genetic relationship of Phellinus baumii, and their relative species by ITS molecular marker technique, and to provide the reference for Phellinus baumii identification and breeding, the ribosomal DNA internal transcribed spacer (rDNA ITS) region was amplified and sequenced to identify the 22 species of Sanghuang which were collected from domestic and detect its genetic diversity. Based on rDNA ITS sequences, the genetic distance and phylogenetic tree were obtained. Results showed that there were distinct genetic divergences among 22 species of Sanghuang, which formed three separate species cluster in the topology tree obviously with high bootstrap value. Meanwhile, two counterfeit Sanghuang strain, Fuscoporia gilva and Inonotus baumii, were detected successfully, and the certified Sanghuang germplasms were distinguished as Sanghuangporus sanghuang unambiguously by BLAST analysis. The results of ITS analysis revealed that Phellinus baumii had the plentiful genetic diversity and the genetic relationships were consistent with morphological characters of taxonomy. ITS method was efficient for identification of Phellinus baumii, which could provide a scientific basis for the resource collection and identification of the species in Phellinus baumii. |
