查询词典 auxin

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.

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。

目前已知的植物激素中只有生长素具有极性运输这一特征。

The inhibition of coleoptile elongation is alleviated when exogenous auxin was added to the medium under the low concentrations of Cu2+ stress. However, under high concentrations of Cu2+ stress, as the toxicity is so much, exogenous auxin is not available any further.

小麦胚芽鞘的生长只表现为细胞的伸长，原理为生长素作用的结果，外加生长素，发现生长素缓解了重金属铜对胚芽鞘伸长作用的抑制，而在高浓度时，由于毒害太大，所以无效。

Generally it was in favor of fresh weight increased rate of callus of Ardisia spp to use 2, 4-D instead of using IAA or NAA, while the influence of auxin on dry weight increased rate of callus of Ardisia spp was connected with explants and auxin concentration used.

总体上生长素类使用2，4-D比使用IAA或NAA更有利于紫金牛属植物愈伤组织的鲜重增长，干物质积累则还因种和外植体以及激素浓度而异。

While the content of IAA was significantly positively correlate with the activity of POD both during the early and later stage of strawberry fruit development, suggesting that IAO might play the crucial role in oxidized decomposition of IAA, yet POD might involve in the maintaining of dynamic balance of auxin and cooperat with it to promote the fruit development. These might put a substantive foundation to investigate the action mechanism of auxin in the development of strawberry fruits.

表明草莓花托中对IAA的氧化分解起主要作用的可能是IAO，而POD除了参与IAA分解之外，可能还与维持生长素的动态平衡、协同促进果实的生长发育有关。
