  4. In the present study, aflp ( amplified fragment length polymorphism ) markers was used to examine population of abies yuanbaoshanensis in order to understand the level of population genetic variation and genetic structure. the result would help to evaluate its evolutionary potentiality and the degree of being endangered and could provide scientific basis for making right protection strategy. high - quality dna was extracted using ctab method from those tender leaves of forty - three fully - developed trees in population abies yuanbaoshanensis

    本研究選用一種高效的檢測遺傳變異的分子標記? ? aflp技術來分析元寶山冷杉種群的遺傳多樣性,旨在了解該種群在分佈區內的遺傳變異水平和遺傳結構情況;研究結果將有助於更清楚地認識這一瀕危類群的生存潛力和瀕危程度,而且可以為制定何種挽救和保護措施提供科學的依據。
  5. And the two pah ' s of pcr primers that bind to the adapter and the sequence of f fragment close by tn5 respectively were also designed. the genomic dna of b8 was isolated, digested with bamh i, and ligated to the adapter. using the two pairs of the primers, two rounds of pcr were performed hi turn and a fragment of 239bp was amplified successfully. lt was proved by cloning and sequencing that 18bp of the fragment is the sequence opposite to f fragment on the left of tn5 insertion site in b8f, the other is part of the 728 bp of f fragment. this result makes it possible to continue to carry out chromosome walking, to clone and sequence the whole genes of b fragment and f fragment, and to reveal the antagonistic molecular mechanism of b8

    試驗研究設計併合成了由40和44個堿基的寡聚脫氧核苷酸組成的染色體爬行接頭,在接頭序列和測定的f片段近tn5的序列上,設計了2對染色體爬行用的pcr引物,從b8菌株中提取基因組dna , bamhi酶切,與染色體爬行接頭連接,依次用2對引物進行pcr ,擴增出239bp產物,經克隆、測序,發現其中18bp為擴增的相應于f片段在b8f菌株tn5插入位點對面的序列,其餘則為f片段728bp序列的一部分,為進一步進行染色體爬行,克隆和測定整個b和f基因,揭示陽菌株的拮抗分子機制提供了技術資料貯備。
