Given the known reaction mechanism and general chemical considerations, we propose that nicotine, when used as the carbon source by P. putida J5, is catabolized to pyruvic acid via pyrrolidine pathway and then participates in the synthesis of vitamin pantothenate and CoA, which supply the energy for the normal functioning.

通过对突变位点基因的功能分析推测，假单胞杆菌可以将尼古丁代谢为2，5-二羟基吡啶，而2，5-二羟基吡啶可以进一步转化为丁烯二酸和丙酮酸，进而参与了泛酸和 CoA 的合成，为生理代谢提供基质。

This method is more simple and inexpensive than screening cDNA library, and can be easily adapted to clone other genes. An Amorpha fruticosa cDNA clone encoding UDP-glucose pyrophosphorylase, a key enzyme producing UDP-glucose in the synthesis of sucrose and cellulose, was cloned by using this method.

本论文利用此方法首次从紫穗槐中克隆了与纤维素合成前体----尿苷二磷酸葡萄糖的代谢有关的尿苷二磷酸葡萄糖焦磷酸化酶基因和与木质素合成相关的4-香豆酸：CoA连接酶(4CL)基因的全长cDNA序列，并由此推测出相应的氨基酸序列。

Four different catechin content cultivars were selected from our tea germplasm appraisal database to assay the gene expression level of the seven genes, flavonol synthase, dihydroflavonol-4-reductase, leucoanthocyanidin reductase, anthocyanidin synthase, etc, which were involved in the flavonoids biosynthesis. The result showed that, the DFR and LAR transcripts were expressed increased with the increasing of tea catechin contents. Nevertheless, the others did not show this tendency clearly.

利用半定量PCR技术检测总儿茶素含量不同的4个茶树品种中与类黄酮合成相关的黄酮醇合成酶、二氢黄酮醇－4-还原酶、无色花色素还原酶、花色素合成酶等7个基因的表达情况，结果表明DFR和LAR基因的表达量与茶树中总儿茶素含量呈一定的相关性，而其他基因则与其相关性不大。

Mutation of the AZELAIC ACID INDUCED 1 (AZI1) gene, which is induced by azelaic acid, results in the specific loss of systemic immunity triggered by pathogen or azelaic acid and of the priming of SA induction in plants.

可感应壬二酸的壬二酸感应基因(AZI1)的突变，导致了由病原体或植物体中的壬二酸和SA感应起始所触发的特定性丢失。

Photosynthetic traits of Ningai 1 and its 4B-monosomic, nullisomic line were investigated in this paper(Rht3 gene was located in 4B-chromosome). 4B-chromosome has the positive effects on photosynthetic rate, chlorophyll content, RuBP carboxy lase content and activity, leaf conductance, chlorophyll relatve steady phase and photosynthetic avtive duartion and these effects are accumlative. So 4B-chromosome has the promoting influence on photosynthesis.

本文系统地研究了带有Rht3基因的4B染色体二体(宁矮1号)、单体(宁矮1号M4B)、缺体(宁矮1号N4B)材料的光合特性，发现带有Rht3基因的4B染色体对光合速率、叶绿素含量、RuBP羧化酶含量及活性、叶片导度均有正效应，并有累加作用，而且对叶绿素含量缓降期和光合速率高值持续期也有正效应，因此带有Rht3基因的4B染色体具有促进光合作用的效应。

The positive signal of ER and ER mRNA distributed in parenchymal and non-parenchymal hepatic cells, especially near the hepatic centrolobular and periportal areas. Ovariectomy decreased ER level and ER mRNA expression significantly (P＜0.05). Hepatic ER and ER mRNA concentration were elevated after treatment with estrogen in both ovariectomy and sham ovariectomy fibrotic groups (P＜0.05), and the elevation of ER was correlated with a marked decrease in hepatic damage and fibrosis.

5肝脏ERα及其mRNA基因的表达分布于肝细胞及肝脏非实质细胞，特别以肝脏中央静脉和门脉周围为主；卵巢切除减少ERα及其mRNA基因的表达（P＜0.05）；雌二醇治疗在肝纤维化和卵巢切除大鼠均提高肝脏ER及其mRNA基因的表达（P＜0.05），其增加程度与肝脏组织学损伤、纤维化指标的降低程度以及肝脏胶原沉积减少相平行。

About 2/3 genes in human being which cause diseases including those associated with cancer, can be found in Drosophila as homologues.

在对果蝇与人类基因的比较中，发现三分之二引发人类疾病的基因在果蝇中都存在有类似的基因。

Axonal degeneration similar to that observed in KIF 1A mutants has also been reported for several neurodegenerative diseases such as senile dementia and most recently Charcot-Marie-Tooth disease type 2A by another synaptic vesicle precursors transporter KIF1B knockout mice. In some neurodegenerative diseases, neuronal cell death caused by defects in the transport of synaptic vesicle precursors by KIF1A may be involved.
