upstream promoter element 中文意思是什麼

upstream promoter element 解釋
上游啟動子元件
  • upstream : adv. 向上游，溯流。adj. 1. 溯流而上的。2. （石油工業等）上游的，和石油的勘探、開采及輸送到起運港口有關的〈石油工業此後的提煉等過程則稱為下游（downstream）產業〉。
  • promoter : n. 1. 增進者，助長者；振興者，獎勵者；後援人；（通常指惡意的）煽動者。2. （企業等）發起人；推銷者。3. 【化學】促進劑，助催化劑。4. （宗教裁判的）起訴人。
  • element : n 1 要素；成分；（構成）部分；分子。2 【化學】元素；【數學】元，素；【機械工程】單元；單體；【無...
  1. ( 3 ) on the basis of the deletion analysis, three substitution mutants ( ml : 6bp sequence upstream of gcc box m2 : gcc box and m3 : g box - like sequence ) by pcr were designed to isolate the essential ja - responsive element. transgenic tobacco plants containing promoter substitution constructs were generated by agrobacterium - rnqdiaied leaf transformation. loss - of - function experiment, using transient expression analysis of gus reporter genes, confirmed that gcc box act as an essential element to respond ja signaling in pdf1. 2 promoter

    （ 3 ）在缺失突變的基礎上，通過對gccbox及其相鄰的上下游六個堿基進行取代突變，將突變啟動子與gus構建融合基因，在煙草中受heja誘導的瞬時表達結果表明， h1和m3的突變對該啟動子應答ja信號的影響很小，而m2 （ gccbox的突變）則幾乎使該啟動子應答ja信號的功能完全喪失，所以gccbox是該啟動子中應答ja信號的必需元件。
  2. The structure of the seed - specific promoter matches the characteristics of the promoter, having a basal promoter, initiator and upstream element

    種子特異性啟動子的結構符合類啟動子的特點，具有基本啟動子、起始子和上游元件。
  3. Extension of low k + treatment to 12 hours did not increase the binding sites or protein abundance either. among ros species, h2o2 was specifically involved in the up - regulation of na, k - atpase induced by low k. 96 base pairs of upstream of na, k - atpase subunit promoter was the key cis - element in transcriptional regulation of promoter activity

    Ros對鈉鉀atp酶亞基啟動子的刺激作用縮小至編碼區上游96堿基對，該序列包含多個潛在sp1轉錄因子結合位點，研究也表明sp1參與了低鉀對鈉鉀atp酶的調節作用。
