frankia 中文意思是什麼

frankia 解釋
弗蘭克菌屬
  1. In addition, we also found that an evident crossing - infection happened in three frankia strains tested, which were respectively isolated from myrica and casuarina

    此外，聚類分析還表明，不同宿主來源的菌株之間存在著交叉，特別是來自於木麻黃和楊梅的菌株，其交叉尤其明顯。
  2. The miscellany appeared in strains of myrica, casuarina and alnus were also partly coincident with what normand et al. ( 1996 ) and li zhizhen ( 2002 ) obtained : the clusters devided by the isolates from the myrica and casuarinahave grest genetic diversities. besides the analysis of the strains, we also tried to extract the dna of frankia from the nodules directly and analyse them also with the method of pcr - rflp

    這些結果與baker （ 1987 ）通過交叉感染試驗將來自不同宿主的50株frankia菌株分成4個類群的結果部分一致，但也暗示其可能具有局限性；此外，分析楊梅和木麻黃菌株所得到的結論支持了normand等（ 1996 ）與華中農業大學碩十研究生學位論文李志真（ 2002 ）所得的結論，即木麻黃和楊梅的菌株比較混雜，兩者都不能成為獨立的類群。
  3. Heavy metal resistance of frankia strains from root nodule of myrica rubra

    菌對重金屬的抗性
  4. Genetic diversity which was determined by the analysis of 16s rdna - rflp and 16s rdna - sequencing were carried out on frankia strains isolated from the root nodules of different actinorhizal plants, including myrica, casuarina, alnus and coriaria. the main results of the research project were as follows

    本研究課題對來自楊梅（ myrica ） 、木麻黃（ casuarina ） 、榿木（ alnus ）和馬桑（ coriaria ）的13株frankia菌純培養的16srrna基因進行了pcr - rflp分析和部分菌株的序列測定，初步探討了弗蘭克氏菌的遺傳多樣性和系統發育地位。
  5. Then the genetic distance and shannon information index among these 13 strains were obtained by using the software popgen2 on the basis of pcr - rflp patterns. the phylogenetic tree was constructed by using the upgma algorithm method ( mega2 software package ). the shannon information index indicated that there was a higher genetic diversity among the frankia strains and some strains had a big genetic distance with others

    根據酶切圖譜，通過popgen2軟體計算各供試菌株之間的遺傳距離；用shannon信息指數計算種群遺傳多樣性；利用upgma法（ mega2軟體）對所獲得的遺傳距離矩陣進行聚類分析，得到13株供試frankia菌株間系統發育的聚類分析樹狀圖譜。
  6. And through blasting with other strains published in the genebank, we got four clusters. fmr61, fcg07 and fce42 have higher similarities and they miscellanyed with strains isolated from alnus, they formed cluster i ; fmrl6 and 2215 had closer relationships the frankia strains that infected the plants of elaeagnus, rhamnaceae and hippophae, they formed cluster iv

    選取其中5株供試菌株進行16srdna全序列分析，通過網上blast 、計算機軟體聚類分析和與其它已發表序列的菌株相比較進一步表明來自木麻黃和楊梅的菌株有著明顯的交叉，它們的分群結果比較混雜。
  7. Combining the analysis of the conservative region of 16s rrna gene of prokaryote, such as e. coli, rhizobia and several frankia strains, we designed several sets of primers to amplify the 16s rrna gene of the frankia strains tested. through tentative experiments with these primers, we screened out primers uf / ur and ec27f / frl717r

    通過比較已發表的原核生物，如大腸桿菌、根瘤菌和弗蘭克氏菌的16srrna基因全序列的保守區，設計了8對引物並篩選出可適用於擴增13株供試菌株16srrna基因接近全長序列的引物： uf ur和ec27f fr1717r （產物大小約1500bp ） 。
