Nicotianamine synthase gene has an important function in the Fe-deficiency response of graminaceous monocots, and it catalyzes substance to nicotianamine which plays an important carrier in the internal transport of Fe(superscript 2+) and other divalent metal ions. Nicotianamine can bind with Fe(superscript 2+) to form Fe(superscript 2+)-NA complex and protect plants from toxicity in acidic soil.

烟酰胺合成酶基因在单子叶禾本科的缺铁胁迫应答反应中起着关键作用，它的催化产物烟酰胺是铁及其他二价金属离子在体内吸收和转运的重要载体，且能与Fe(上标 2+)结合形成Fe(上标 2+)-NA复合物，从而使植物在酸性土壤中免受铁毒害。

For example, promises that are purely gifts are not considered enforceable because the personal satisfaction the grantor of the promise may receive from the act of giving is normally not considered adequate consideration.

比如，许诺赠与礼物的行为就不是一个可强制执行的合同，因为赠与者从赠与行为中得到的个人满足感在法律上并不认为是一个充分的对价。

The different fishes which are employed in the present studies are wild-type salmon, cultured salmon of freshwater and seawater, sea perch and fat greenling. The complete CT gene sequences of salmons are obtained by PCR amplification. The partial CT sequences of sea perch and fat greenling are obtained by in vitro cloning PCR method. Alignment of obtained CT sequences with other fish CT shows that CT appears to be well conserved among the same family. And the relative in taxonomy is far away, the similarity of different fish CTs is low. On the contrary, the closer the relative in taxonomy is, the higher the similarity of different fish CTs is. The sCT is expressed in pGEX-4T-X by recombinant form . We also succeed in the research of sCT expression alone by expression PCR. In addition, sCT antiserum is obtained using GST-sCT as antigen, and the high titer is tested by double immunodiffusion. In the rat bioassay, administration of 50 μg recombinant protein evoked significant hypocalcemia at 1 h after the data are analyzed by t-test.

本文用PCR方法克隆了野生鲑鱼、养殖鲑鱼的降钙素基因，并应用体外克隆PCR的方法首次克隆出鲈鱼、六线鱼降钙素的部分基因序列，通过对克隆的降钙素序列的比较研究，结果显示同一科的鱼降钙素序列保守性较高，同时，根据降钙素的部分氨基酸序列进行了降钙素相似性的比较研究，结果显示在分类学上，分类地位较远的鱼，其降钙素相似性较低，分类地位越接近的鱼，其降钙素相似性越高；我们利用谷胱甘肽S-转移酶(Glutathions S-transferase，GST)融合表达载体pGEX-4T-X对克隆的鲑鱼降钙素基因进行了融合表达研究，应用表达PCR的方法对降钙素基因的独立表达进行了初步的研究探索，并将纯化的融合蛋白作为抗原，获得了高效价的兔抗鲑鱼降钙素免疫血清；生物活性研究表明，大肠杆菌表达的融合蛋白具有显著的降血钙作用。
