We also measured the content of indogenous IAA in different nodes in monoecium and gynoecium, and the variation of indogenous IAA and gibberellic acid at the different developing stages in cucumber after being treated with exogenous GA〓: the variation of ethylene release and the activities of ACC oxidase at the different developing stages after being treated with exogenous IAA and GA〓.

进一步比较了外源GA〓处理后，不同发育阶段雌性系黄瓜品种中的内源生长素和赤霉素含量的变化情况，结果表明：GA〓处理后的雄性化作用与降低黄瓜植株中内源生长素含量以及提高内源赤霉素含量有关，而生长素含量的降低则可能抑制了内源乙烯的释放。

These results suggested that the stimulation effect of local nitrate on LR growth is dependent on auxin. And the auxin mainly comes from the basipetal transport from shoot to roots, but not from the seed or the basipetal transport of auxin from root tip to LR growth sites.

这些结果表明，局部供应硝酸盐对侧根生长的促进作用依赖于生长素，这些生长素主要来源于地上部生长素向侧根生长部位的直接供应，而不是来源于种子或由根尖向侧根发生部位的生长素向基运输。

In order to explore the mechanisms of auxin action and metabolism, as well as the changing characteristics of its relative enzymes, IAA content in strawberry fruits with different treatments was determined by HPLC. Content of IAA and the activity of IAO and POD in fruits treated by NPA or TIBA, the inhibitor of auxin transport, were analyzed to investigate the changing characteristics and possible source of auxin, as well as the relation among IAA, POD and IAO. Results were showed as the followings: there had a certain count of IAA in receptacles and achenes, and IAA content in achenes was higher than that in receptacles.

摘要为了探索草莓果实中生长素的代谢变化及其发挥作用的机理，利用HPLC定量测定了草莓果实发育过程中瘦果和花托中的吲哚乙酸，结合生长素运输抑制剂NPA和TIBA处理考察了草莓果实中IAA含量以及不同存在状态的生长素氧化酶和过氧化物酶活性变化，综合分析了草莓果实中IAA 的变化特性、可能来源及其与生长素代谢相关酶的关系。

Methods 180patients with liver injury owed to various pathogeny were randomly divided into3groups,which were control group A treated with hepatocyte growth-promoting factors,control group B treated with hepatocyte growth-promoting factors and Jinshuangqi,and treatment group treated with hepatocyte growth-promoting factors,Jinshuangqi and Tongkang tablet.

应用随机对照方法，将不同病因引起的180例转氨增高患儿分成3组，分别为促肝细胞生长素组、金双歧联用促肝细胞生长素组和促肝细胞生长素、金双歧和童康片三药联用组。

Root initation may be stimulated by auxin from the shoot, and auxins have been shown to move toward the root eips.

生长素刺激细胞增大，通过抑制侧芽的发育从而维持顶端优势，根的发生可能是通过芽产生的生长素刺激的，而且生长素可以沿着根尖运输。

In this study, according to the classification and activity of auxin plant hormones the authors carry out docking experiments with four auxins, IAA, 1-NAA, 2,4-D, 2-NAA, and the receptor.

依据生长素分子的分类以及生长素活性的不同，选取四种生长素分子IAA， 1-NAA， 2，4-D， 2-NAA分别与生长素受体分子进行分子对接计算研究。

First, the significant of co-factor InsP6 and center water in the mechanism of auxins are explored by docking; second, the experiments that compared with the docking rusults of two situations involving fully rigid and selective flexible of active residue of the receptor TIR1 illuminate that selective flexibility docking by AutoDock4 reports more rational results, so that, AutoDock4 dockings are implemented with TIR1-Auxins; third, AutoDock4 docking by TIR1-Auxins-Aux/IAA illuminates that auxin as a molecular glue enhances the interaction between TIR1 receptor and Aux/IAA substrate by the weak interactions, such as hydrogen bond and hydrophobic interaction, furthermore, the weak interactions between receptor protein and ligands greatly influence on auxin activity of auxin ligands.

首先， 通过分子对接计算研究辅酶InsP6以及中心水分子在生长素反应中的重要作用；其次，比较受体大分子完全刚性以及活性残基部分柔性的两种情况下的分子对接结果，说明AutoDock4实现了受体分子活性残基的部分柔性而使对接结果更加合理，进而使用AutoDock4方法对TIR1-Auxins体系进行对接计算；最后，对TIR1-Auxins-Aux/IAA体系进行分子对接计算，结果表明，生长素配体分子作为&分子胶水&直接与受体大分子TIR1以及底物多肽Aux/IAA形成强的弱相互作用，如氢键作用、疏水相互作用，促进了受体TIR1与Aux/IAA底物之间的结合，进而说明氢键作用和疏水相互作用等弱相互作用对于生长素分子的活性具有很大的影响。
