表型變異
  • phenotypic : 表型的, 顯型的
  • variation : n 1 變化，變動。2 變量，變度，偏差。3 【語言】語尾變化；變體，異體；【數學】變分，協變；順列；【...
  1. A. thalianas were respectively introduced by ion beam with a collection of donor dna having a gradient genetic relation with a. thaliana. in vegetative phase of tl, the ratio of phenotypic variation showed no distinct difference among these transformed populations

  2. The prescription of the tissue culture of petunie hybrida and the dna level of phenotypic variation seed lings produced by tissue were discussed

  3. Phenotypic variation in chinese catfish silurus asotus linnaeus

    鯰魚形態特徵參數與體長關系及變異分析
  4. Mint total dna was transferred into a. thaliana mediated by ion beam with the influence of 0. 5 10 1. 5 1017 and 2. 5 1017 ions / cm2, respectively, which were on the bridge of saddle. among three transferred populations, their budding, seedling, growth and phenotypic variation took on obvious difference. combining these facts, the influence of 1. 5 1017ions / cm2 was decided as transformation influence of the following work

    我們從另外一個角度出發，在離子注入劑量-擬南芥菜存活曲線的基礎上，選擇不同的離子劑量介導薄荷全dna轉化擬南芥菜，根據各個轉化群體在遺傳和生理上的不同變化，選擇1 . 5 10 ~ （ 17 ） ions cm ~ 2作為我們以後轉化工作的轉化劑量。
  5. First, the fact that the phenotypic variation in t1 mainly resulted from transformation of exogenous dna rather than ion beam mutagenesis was verified by rapd - pcr amplification to mutants, exogenous dna - transferred plants and ion beam - implanted plants. second, an absent band, marked by sieg - isso, was found in the rapd - pct amplification to t - 6 and its progenies, which meant that the corresponding mutation was hereditary. this mutation was located between exon 1791 - 2691 and exonl - 395 of abc - transporter gene

    T - 6和其t2代植株的rapd - pcr擴增結果中均存在缺失條帶s _ （ 168 - 1850 ， ）表明該缺失條帶對應的變異是可以遺傳的，該變異發生在abc鄭州大學博士論文摘要介即sporter基因exon1791一2691和exonl一395之間。
  6. Phenotypic variation in actinobacillus actinomycetemcomitans

    表達的變化
  7. Secondly, we compared and analyzed the growing state, plant height, flower shape and seed setting ability, etc, of m2 tube seedlings and m3 greenhouse plants treated with low - energy n *. we found that the growth rates of m2 tube seedlings and m3 greenhouse plants were lower than that of control and the growth rate decreased with the treated doses from 60x1015, 40x1015 to 80 x 1015. vfe also found that many phenotypic variations appeared in m2 tube seedlings, including yellowing, lethality, semi lethality, morphological variation ( such as leaf and flower shape variations, plant height variation, etc )

    最後，對80次劑量處現的擬南芥的mz代試管稍和60次劑員處理的m3代溫室茵採用rapd技術對dna的差異進行了分析，檢測發現經低能n 」注入處理的材料，其pcr條帶缺失或增加，而對照組未發現明顯的變化，而且條帶的變異率隨劑量的升高而上升，從引物的角度看， 80次劑量處理的比代試管苗的多態性表現為67
  8. Finally, the variant line tc243 - 2, was analyzed by rapd - pcr amplification with 100 random primers. the results suggested that phenotypic variation came from exogenous dna transformation rather than exogenous pollen contamination. a mutation corre

    用100條隨機引物對tc243一株系的rapd一pcr擴增結果表明該株系的變異不是來自外源花粉的污染，同時發現了特異條帶5270 _ 1600對應的變異在tz一ts代能連續穩定遺傳。
  9. By shannon phenotypic diversity index from rapd data, it was found that 69. 33 % of molecular variation existed within subpopulations while 30. 67 % of which among subpopulations

    又利用neis指數估計叉毛蓬居群的遺傳多樣性，也表明大部分的分子變異存在於亞居群之內（ 69 . 48 ） 。
