Cysteamine exists in the living animals and plants, owing to sulfhydryl and amido it has special biological function to participate in the normal metabolic process , for example, the decreasing of Somatostatin, the influence of the synthesis and the excrete of GH, etc .

半胱胺是天然存在于动物、植物和人体内的生理活性物质，含有活性的巯基和氨基具有特定生物学功能，参与正常代谢过程，如降低机体生长抑素（Somatostatin，SS）水平 [2，3]，影响GH的合成和分泌等[4]。

The results showed that both two autotoxic substances exhibited allelopathic promotion at low concentration and allelopathic inhibition at high concentration on pepper seed germination and seedling growth.

结果表明：这两种自毒物质对辣椒种子萌发和幼苗生长具有低浓度促进，高浓度抑制的化感效应。

Base on these phenomena, this study investigated the different responses of roots of these two species to cinnamic acid, in respect of the metabolism of reactive oxygen species, metabolism of water in plant, nutrient ion uptake and the growth in order to clarify the mechanism of the autotoxic effect of cinnamic acid on cucumber.

基于这一有趣的现象，本研究以黄瓜及黑籽南瓜为材料，通过对比研究两者受到自毒物质肉桂酸(cinnamic acid，CA)侵害时在活性氧代谢、水分代谢、养分吸收及生长等方面的响应差异，进一步探讨CA对黄瓜生理代谢过程的影响机制，主要结果如下： 1 0.25mM CA处理3天激发了黄瓜根系质膜NADPH氧化酶活性的显著提高，增加了活性氧H_2O_2和O_2~

Fast propagation of Balsamine was studied and the results were listed as below.

摘 要：近年来，在甲壳动物大颚腺中发现了一种具有保幼激素活性的物质——法呢酸甲酯，它是与昆虫保幼激素Ⅲ结构相似的一种倍半萜类化合物，对甲壳动物的生长、发育和繁殖有重要调控作用，而MF的分泌受到眼柄等因子的负调节作用。

The conidia formation was inhibited on the PDA agar plate with the culture filtrates though the spores germinated and formed their hypha in certain degree. Growth suppression, increasing branches of their offset and swelling in the middle and/or the top of the hyphae were observed with microscope and scanning election microscope. The longer time the treatment, the more severe the hyphae aberration was, some of them were altered as beadlike, some offsets formed cluster-like structure.

在普通光学显微镜和扫描电子显微镜观察显示，两菌株均可抑制香蕉炭疽病菌菌丝生长，造成菌丝分支增多，顶端和中央膨大，随着时间的延长畸变结构增加，菌丝呈念珠状或菌丝分支显著增多，且顶端细胞变形膨大聚集成簇，菌丝壁穿洞，内含物质泄漏，终使细胞崩解和消融，变成球状的空泡。

A bacterial strain using phenol, benzoate, naphthalene, biphenyl and benzothiophene as sole carbon and energy sources was isolated from waste sludge and was identified as Rhodococcus sp. strain DF51 according to morphological, physiological and its 16S rRNA gene sequence.

从太原市郊苯酚污染的土样中分离到一株能以苯酚、苯甲酸、萘、联苯和苯并噻吩为唯一碳源和能源生长，并且具有同时分解单环和双环芳香类物质能力的菌株，经生理生化和16S rDNA基因序列分析鉴定为红球菌DF51Rhodococcus sp。

Chalcone synthase gene is one of the key genes in phenylpropanoids pathway for producing flavonoids,isoflavonoids,anthocyanin and other secondary metabolism products in plants. It plays important roles in the physiological and biochemic progress of pigment synthesis,defense response and plant fertility.

查尔酮合成酶基因是苯丙氨酸代谢途径中的关键基因，在类黄酮类物质合成中扮演着重要的角色，调控着色素合成、防御反应、植物育性等生理生化过程，对植物的生长发育起着至关重要的作用。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。
