【中文摘要】 以我國云南和四川產(chǎn)的5個塊菌菌株為試驗材料,提取塊菌DNA并對rDNA的ITS序列分析試驗條件的初步研究,結(jié)果表明:運用常規(guī)CTAB法提取塊菌子實體DNA,獲得的DNA產(chǎn)量高,可以滿足本試驗的要求;明確了rDNA ITS區(qū)域的適宜PCR擴增和克隆條件;獲得4個長度為650bp、1個長度為800bp的PCR產(chǎn)物;將PCR產(chǎn)物連接到PMD18-T載體上,轉(zhuǎn)化E.coliJM109,獲得了陽性克隆,供進一步序列分析用。

【英文摘要】 5 truffle samples clustered from Sichuan and Yunnan were selected to extract DNA and the internal transcribed spacer(ITS) regions of nuclear ribosomal DNA was amplified.The results showed: The optimal PCR and clone conditions were assured;The length of 4 samples was 650bp and1 sample was 800bp;The PCR product was linked to PMD18-T vector and transformed into E.coliJM109.We chose the positive clone which would use in the further sequence analysis.
