This article introduced the new progresses on the regulation of ABA biosynthesis in higher plants.

本文介绍近年来ABA生物合成酶调控的研究进展。

Abrin is one of the potent toxins isolated from the beans of plant abrus precatorius.the toxic protein consists of two disulfide-bonded subunits,the a and b chains.the b chain is a galactose-specific lectin that facilitates the binding of abrin to the cell membrane that precedes endocytosis.after entering the cells,the a chain catalytically inactivates 60s ribosomal subunits by removing adenine position 4324 of 28s r–rna,and thereby inhibits protein biosynthesis.

相思子毒素是从豆科植物(abrus precatorius l。)种子中分离的一种细胞毒性蛋白。它由a，b两条链组成，由一个二硫键相联，b链具有半乳糖凝集活性，可与细胞膜上受体结合，帮助a链进入细胞内，a链进入细胞催化失活60s核糖体亚基，从而使细胞蛋白合成被抑制。

The biosynthesis of fatty acid is an essential process for the survival of the organism.

Objective To explore the possibility of aldosterone biosynthesis and expression of aldosterone receptor in rat mesangial ceils in vitro.

目的 探讨培养的大鼠肾小球系膜细胞能够自身合成分泌醛固酮及存在醛固酮受体的可能性。

Most of these peptides are amidated at their C-terminals, which is essential for their full activities. The a-amide comes from posttranslational modification that is catalyzed by α-amidase (α-AE or PAM). The amidation reaction is a rate-limiting step in the biosynthesis of regulatory peptides.

大部分活性肽的C-端是酰胺化的，而且α-酰胺基为多肽的完全生物活性所必需；α-酰胺基来自多肽的翻译后加工，由α-酰胺化酶催化完成，是酰胺化多肽生物合成途径中的限述步骤。

Problems in plant amylopectin biosynthesis and prospects for its application are also presented.

同时提出了该研究领域尚待解决的问题，对其应用前景作了展望。

GBSS is responsible for amylose synthesis especially in the later period.SSS and SBE are associated with amylopectin biosynthesis.

GBSS对直链淀粉积累起重要的促进作用；SSS和SBE对支链淀粉积累起重要的促进作用。

We found the relationship among starch metabolism, metabolisms of other components and gene expressing profiling due to the accumulation of sugar. Then, genes expression patterns of starch biosynthesis in leaves and developing endosperms of 5 maize inbreds were studied for the contribution of different genes to starch biosynthesis in endosperm.

为深入了解玉米淀粉合成的分子调控机理，本研究首先以B73、ae/wx和sh1授粉后15天的胚乳为材料，利用18K Affymetrix玉米基因组芯片平台，研究了突变体材料中基因表达谱的变化，发现了淀粉合成受阻后糖的积累对其它物质代谢和基因表达调控的影响；在此基础上，对可能参与淀粉合成的基因以多个自交系为材料，分析它们在叶片和胚乳发育过程中的表达模式，研究了不同成员对胚乳淀粉合成的贡献。

The results showed the appropriate concentration of taxol (10 μM) or taxotere (35 μM) activate the influxes of H+, ROS accumulation, PAL activity and biosynthesis of taxol, as well as apoptosis, however, the high concentration taxol or taxotere (140 μM) did not show above results. Ten plots of protein were only observed in taxol-induced cells and there were differences at expression level of some plots between control and taxol-induced cells using two dimension electrophoresis, which reflect those differential protein were highly relevant to signal moleculars of cell defense responses, suggesting cell apoptosis and taxol biosynthesis might be parallel or two events in the same pathway of defense responses.

采用二维凝胶电泳技术，分析了taxol诱导细胞产生早期防御响应的蛋白表达差异，发现taxol诱导了10个新蛋白点的表达，其中一些新蛋白点的分子量与细胞信号分子G-蛋白、Ca2+依赖蛋白激酶的分子量接近。

The results implied that NO/ROS-induced ABA accumulation come from de novo synthesis pathway rather than degration of conjugated forms. The protein synthesis inhibitor actidone blocked the NO-induced ABA accumulation while having no effects on ROS-induced ABA accumulation, indicating that the action of NO was gene-expression dependent and that of ROS was gene-expression independent. These results suggested that NO may serve as a stress signal in the regulation of ABA-biosynthesis and ROS may serve as substrate in ABA biosynthesis or be involved in the regulation of enzyme activities.

1ABA合成抑制剂fluridone抑制ROS和NO诱导的ABA积累，表明NO／ROS诱导的ABA积累来源于ABA的从新合成而不是已有结合态ABA的代谢；(2)蛋白质合成抑制剂环己亚胺可以抑制NO诱导的ABA积累而对ROS诱导的ABA积累没有影响，说明NO的作用涉及基因表达而ROS的作用与基因表达无关，暗示NO的作用方式可能是作为一种干旱胁迫信号物质参与ABA合成的调节，而ROS则可能参与了相关酶活性的调节或直接参与了ABA合成的底物反应。
