Expression of Bilirubin Oxidase cDNA from Myrothecium Verrucaria in E. coliThe 1. 6kb bilirubin oxidase cDNA from Myrothecium Verrucaria was excised from plasmid pGEM-T/BOX, and inserted into expression vector, pET-3a which were under the control of a T7 promoter.

用限制性内切酶将1.6kb疣疱漆斑菌胆红素氧化酶cDNA从质粒pGEM-T／BOX切下，插入到表达质粒pET-3a的T7启动子下游，构建成疣疱漆斑菌胆红素氧化酶表达质粒pET-3a／BOX。

Moreover, since both the CSF-box and the octamer are indispensible for LPS-induced G-CSF promoter activity, there might be a coactivation mechanism composed of Oct-2 and NF-κB for G-CSF transcription. However, the mechanism is not yet understood and deserves further investigations.

此外，既然CSF-box以及octamer对G-CSF的启动子活性缺一不可，那麼Oct-2和NF-κB之间可能存在著某种共同调控G-CSF表现的机制，尚待进一步厘清。

The traits of both expression systems are compared; the related coden, vector, and promoter are discussed; the advanced protocol of operation and the strategy for optimization are surveyed in this article.

本文对酵母的一般特性、酵母表达操作、密码子、载体和表达策略、两种不同酵母表达系统的特点等进行了论述，供研究者进行酵母高效表达体系的选择与操作参考。

GUS staining shows that GUS gene was expressed in stems, leaves, calyxes, stamens and siliques in transgenic Arabidopsis plants, with higher expression in green tissue such as stems, leaves, siliques, while invisible in roots, petals, and seeds. The data indicate that MPBQ MT gene promoter was likely to be expressed preferentially in green tissues such as stems, leaves, and young siliques.

GUS组织化学染色结果表明，在MPBQ MT启动子驱动下，报告基因GUS在拟南芥的茎、叶、花萼、雄蕊、种荚均有表达，且在茎、叶、种荚中表达量较高，而在根、花瓣和种子中则没有观察到GUS基因的表达，表明MPBQ MT基因可能仅在拟南芥幼嫩茎、叶、种荚等绿色组织中特异性高表达。

The way of promoter cloning is important for constricting gene engineering vectors and expressing the aim proteins.

启动子的克隆对于构建基因工程载体，表达目的蛋白有着重要的意义。
