auxin a 中文意思是什麼

auxin a 解釋
植物生長素
  • auxin : n. （植物）生長素。
  • a : an 用在以母音音素開始的詞前〉 indefinite art 1 〈普通可數名詞第一次提到時，冠以不定冠詞主要表示類...
  1. It is inconsistent to attribute such a short lag period to a result of an auxin effect on gene activity.

    將如此短暫的延遲期歸結為生長素作用於基因活性的結果走不合適的。
  2. An auxin increases the growth in length of a plant cell, thus causing the curving of a stem, or roof, in phototropism and geotropism.

    植物生長素能加快植物細胞長勢，因此使莖彎曲向著陽光，或使根深扎入土。
  3. Leaf fall the shedding of leaves, usually associated with a fall in auxin concentration

    落葉：即樹葉的脫落，常伴植物激素濃度的降低。
  4. Whenever a plant responds to applied, i. e., unbalanced, applications of auxin, ethylene is produced.

    當一植物對不平衡地施用生長素起反應時，總是產生乙烯。
  5. Our results provided direct evidence that pf40 gene play a role in the tissue development, with knockout this gene the lateral buds were not visible. the plant hormones auxin and cytokinin appear to play a major role in controlling this process, therefore, the concertrition of auxin and cytokinin was measured, however, the concentration of the two hormone was variation a little in transgenic plants, but the ratio of the two was more than 5 fold in the pf40 gained function plant than that in wild type. furthermore the pf40 gene effected differentiation of the vascular bundles in different transgenic plants, results showed the pf40 could change both xylary fibers and vessel

    進一步的實驗發現pf40基因會影響植物側芽發育的早期，即pf40基因作用在側芽形成與發育的早期。對轉基因穀子的組織切片的分析還表明pf40基因引起不同形式的轉基因穀子的維管組織的發育的差異，轉化正義載體穀子的木質部變多，維管系統增多，而反義或干擾的轉基因穀子的木質部數量變少，木質部分化異常。從轉基因的結果可見pf40基因可以減弱植物的頂端優勢，這種作用是通過改變植物體內激素的含量實現的。
  6. By combining the information from the cdna sequences with functions of their homologs, we suggest that two kinds of hormones may play important roles during flower regeneration in a few ways : ( i ) proteolytic system of ubiqutin / 26s proteosome complex, ( ii ) actin - dependent vesicular cycling of auxin efflux carrier, ( iii ) regulating transcription of genes, ( iv ) phosphorylation and dephosphorylation

    經過進一步的篩選，結合序列特徵和同源基因的功能信息對這些基因功能進行了初步分析。認為兩種外源激素可能通過泛素26s蛋白酶體復合體對調節蛋白的降解機制，生長素運輸載體肌動蛋白依賴的小泡運輸，基因轉錄調節，磷酸化和去磷酸化等調節過程誘導風信子花分生組織的再生。
  7. [ c ] iaa is used to measure pat ability in arabidopsis stem under the treatment of quercetin, which promotes auxin transport at the concentration of 25 u m as a result

    測量擬南芥下胚軸長度結果表明， q促進了下胚軸的延伸，這一表型與生長素極性運輸增強相聯系。
  8. Pharmacological evidences show that quercetin - inducing hypergravitropism is structural specific activity, and the second massager such as ca2 + and camp take parts in this process, and polar auxin transport is indispensable. a conclusion can be made from all these results that quercetin, one kind of flavonoid, does not act as pat inhibitor but regulates auxin transport at the level of signal transduction in arabidopsis

    藥物學實驗結果表明， q誘導超向地性來自於末端特異性結構，同時細胞內的ca ~ （ 2 + ）和camp等二級信使也參與了這一過程，並且生長素極性運輸也是發生超向地性所不可缺少的條件。
