Functinal complementation test showed that trehalose-6-phosphate synthase mutant (tps1△), transformed by the open reading frame of SpTPS1 gene, restored growth on the mediam supplemented with glucose as a sole carbon source. This result indicated that trehalose-6-phosphate synthase gene (SpTPS1) of Selaginella pulvinata has biologically activity and is hopful to be applied to transgeneic improvement of plant for abiotic stress tolerance.

酵母功能互补试验证明，用SpTPS1基因开放阅读框转化的海藻糖合成酶基因突变（tps1△）酵母菌株，可恢复在以葡萄糖作为唯一碳源培养基上的生长，说明垫状巻柏海藻糖-6-磷酸合成酶基因SpTPS1具有生物活性，可能应用于植物抗逆性的转基因改良。

After 13 months culture, sporophytes began to form. Each gametophyte had several archegonia, and only one sporophyte was produced per gametophyte. The first sporophyte frond was simple and had pinnate venation.

抱子体在经13个月的培养后开始产生，每个配子体虽然有许多的藏卵器，但只产生一株孢子体，第一片孢子体的叶片为单叶羽状脉。

For exploiting and making use of rhizobium species resources of planting leguminous trees in south China,the full_length 16S rDNA sequences of representative strains HJ06 and JJ06 of two rhizobia,isolated from Acacia crassicapa and A.cincinnata in south China,were determined.These sequences were compared with all known rhizobia and related bacteria and an unrooted phylogenetic tree was produced.

为了开发利用我国人工林豆科树种根瘤菌的种质资源，该研究对华南地区两个人工林豆科树种厚荚相思和卷荚相思的根瘤菌两个代表菌株HJ06和JJ06进行了16S rDNA全序列测定，将此全序列与根瘤菌各已知种及相关种的16S rDNA全序列进行了比较及聚类分析，得到系统发育树状图。

For the purposes of this illustration, it is helpful to see valerian as also linked to Gemini.

In the second part of our research, YC-1, an indazole derivative, displayed impressive selective toxicity against the human lung squamous carcinoma cell line NCI-H226 and human kidney tumor cell lines RXF-631L by a panel of 39 human cancer cell lines (JFCR39) screening. Therefore, the molecular mechanism by which YC-1 affects NCI-H226 cell growth was studied.

在本论文的第二部份中，吲唑类化合物YC-1经利用日本JFCR39癌细胞株之抗癌活性筛选后发现，YC-1对於人类肺鳞状上皮细胞癌细胞NCI-H226以及人类肾癌细胞RXF-631L具有高度的抑制选择性，於是我们选择NCI-H226细胞株做为YC-1对抗肺癌之抗癌机制探讨模式细胞。

Objective To research on the lysogenic bacteriophage CTXΦ genome, for isogenous sequences with RS in the chromosomes were found in some strains of ctxAB- E1 Tor biotype isolates in this lab.

At the same time, Merck developed a pentavalent vaccine derived from five human-bovine reassortant strains that together would target the major strains of rotavirus.

此时，美国默克药厂研发了一种五价疫苗，由人及牛的五株病毒品系组成，可对付一些主要的轮状病毒品系。

The analysis of the 16S rDNA sequence indicated that the two strains, CW-02 (accession numbers: AY703031) and CW-03 (accession numbers: AY703031) belonged to the genus Desulfotomaculum (Peptococcaceae, Clostridiales, Clostridia, Firmicutes, Bacteria), and their similarity with D. nigrificans and D. aeronauticumd was 98%.

通过16SrDNA测序以及在线的Blast系列比对分析：两株菌均属于细菌界，厚壁菌门，梭菌纲，梭菌目，蛋白胨链球菌科Peptococcaceae，脱硫肠状菌属，与该属中的种Desulfotomaculumnigrificans和Desulfotomaculumaeronauticumd相似性达到98%。

The full-length genome cDNA containing genetic tags and flanked by Hammerhead ribozyme and Hepatitis delta ribozyme were cloned downstream of the CMV enhancer and the chicken beta actin promoter of the vector pCAGGS. After purified by Plasmid Midi Kit, the recombinant infectious clones named pCAGGmGtAHRT and pCAGGmGtBHRT were directly co-transfected DFI cells indued by Lipofectamine~ 2000. 72h post transfection. the supernatant of cell cuture was harvested and continue passaged in CEF cell. The results of indirect immunofluorescence.

分别在Gt株基因组两端引入了锤头状核酶结构(Hammerhead ribozyme，HamRz)和丁肝病毒核酶结构(Hepatitis delta ribozyme，HdvRz)，并将其克隆在真核表达载体pCAGGS的CMV增强子和β肌动蛋白启动子下游，构建IBDV感染性克隆pCAGGmGtAHRT和pCAGGmGtBHRT，经Plasmid Midi Kit纯化后，在Lipofectamine~ 2000的介导下，直接转染DFI细胞，72h后取上清继续在CEF上传代。
