【中文摘要】 CTAB法提取靈芝菌絲體總DNA,再以核糖體DNA轉(zhuǎn)錄間隔區(qū)(ITSⅡ、IGRⅠ-PCR RFLP)結(jié)合隨機引物擴增多態(tài)性(RAPD)標記分析30個靈芝菌株間的親緣關系。結(jié)果表明,ITSⅡI、GRⅠ-PCR RFLP產(chǎn)生了47條帶,其中42條顯示出多態(tài)性,通過聚類分析將30個菌株分成七大類,包括紫芝、黑靈芝、樹舌靈芝、薄樹靈芝四大類,以及另外三個無法確定具體歸屬的類群,但沒能將赤芝與松杉靈芝區(qū)分開。RAPD從247個隨機引物中篩選出8個隨機引物,共檢測到69個多態(tài)性位點并全部顯示出多態(tài)性,通過聚類分析將供試的30個靈芝菌株全部區(qū)分開。

【英文摘要】 Total DNA of Ganoderma mycelium was extracted by the method of CTAB,and genetic relationships among thirty Ganoderma strains were analyzed based on ITS Ⅱ、IGR Ⅰ-PCR RFLP and RAPD.The results showedthat 47 bands were obtained based on ITSⅡ,IGR Ⅰ-PCR RFLP,and 42 bands of them were polymorphic.Thirty strains were divided into seven species: Ganoderma sinense,Ganoderma atrum,Ganoderma applanatum,Ganaderma capense(Loyd) Teng and other three groups(their species are still unknown) through dendrogram aralysis.Only 8 primers produced stable results among 247 random primers by RAPD.Total 69 loci were obtained by using 8 primers and all of them were polymorphic. Based on these 69 loci,thirty Ganoderma strains were differentiated.
