Endogenous auxin, or indole-3-acetic acid ( IAA), plays a central role during root induction in woody plants. 生长素类物质在木本植物生根过程中发挥重要作用。
Gardeners and farmers have used the plant hormone auxin for decades, but how plants produce and distribute auxin has been a long-standing mystery. 园林工人和农夫用了几十年的植物生长剂却不知道植物是怎么生长的,植物生长剂是怎样合成、分布扩散的也一直是个长期困扰的谜。
Auxin levels differ along a shoot and affect which flowers grow, the auxin levels themselves being affected by day length, temperature and quantity and quality of light. 一条茎上的生长素水平存在差异,这也可能影响到长出什么样的花,生长素本身的水平受到日长、温度、光强和光质的影响。
Contrary to the current thinking in the field, the research shows that the patterns in which auxin is produced in the plant influence development, a finding that can be applied to improving crops. 与当前此领域的观点相反,此研究显示植物中生长剂的产生方式影响着其生长发育,此发现应用于庄稼的改良。
Anchored to the base of the TIR1 pocket, auxin binds to a partially promiscuous site, which can also accommodate various auxin analogues. 与TIR1结合区的碱基连接后,植物生长素绑定到局部杂乱结合域,该结合域也能容纳不同的生长素类似物。
Auxin is a pivotal plant hormone that controls many aspects of plant growth and development. 植物生长素是调控植物生长发展多方面的关键性植物激素。
The perception of plant cells to the signal of auxin starts at the combination of auxin-binding protein with auxin molecular. The combination initiates a serious cascade magnifying reaction in signal transduction of auxin. 植物细胞感受生长素的信号是由生长素结合蛋白和生长素分子相结合,从而引起生长素信号传递的一系列级联反应而完成的。
Many studies show that plant hormones, such as auxin, gibberellic acid, ethylene, and etc., play a vital role during the fiber growth and development. 研究表明,植物激素对纤维的生长发育起到重要的作用,例如生长素、赤霉素、乙烯等。
Such a large range it can work, mainly because auxin can act as a signal factor and activate a series of downstream signal pathways. 生长素能在如此大范围对植物发育进程中起作用,主要是因为它可以作为信号因子激活下游一系列信号途径。
Auxin plays a key role in regulating wood formation through its effects on cambial activity and vascular tissue differentiation in plants: controlling the period of cambial activity, maintaining the morphology and arrange orientation of fusiform cells, regulating the differentiation of phloem and xylem. 生长素在形成层活动和维管组织分化中起着极其重要的调控作用,包括:控制形成层活动周期,维持纺锤状细胞的形态和排列方向,控制木质部和韧皮部的分化。
It was proved that leaf was the best explant for inducing callus. The effects of different hormone combinations on callus formation were greatly, and auxin 2,4-D is a key factor in callus formation. 不同激素组合对愈伤组织的形成影响很大,其中生长素2,4-D是愈伤组织形成的关键因素。
Most recent study shows that SA causes global repression of auxin-related genes, and this inhibitory effect on auxin signaling is a part of the SA-mediated disease-resistance mechanism. This indicates that auxin also plays key role in plant defense. 最近的研究发现,水杨酸全面抑制生长素相关基因的表达,且水杨酸对生长素信号通路的抑制是水杨酸介导的抗病防卫反应机制的一部分,说明生长素在植物防卫过程中也起着重要作用。
Ethylene can regulate auxin content, which has a great influence on plant development and morphology. 乙烯能够调节生长素的含量,而生长素对植物发育形态影响很大。
Indoles acetic acid ( IAA) is a kind of auxin which plays a key role in plant cell division, growth and differentiation. 吲哚乙酸(IAA)作为一种植物生长激素,在植物细胞分裂、生长、分化过程中起关键作用。
This study was to explore the special aquatic vegetables Vallisneria barbed effective means of vegetative propagation of tissue culture in the process of disinfection methods, media types, explant selection, light temperature treatment, the choice of auxin and cytokinin etc. A comparative study. 本研究为探索特种水生蔬菜刺苦草无性繁殖的有效途径,对组织培养过程中的消毒方法、培养基种类、外植体选用、光照温度处理、生长素和细胞分裂素的选择等方面进行了比较研究。
Auxin is the first plant hormone discovered in experimental biology, regulates a host of plant developmental and physiological processes, including embryogenesis, vascular differentiation, organogenesis, tropic growth, and root architecture. 生长素(auxin)是最早被发现的一类植物激素,调控许多植物的生长和发育过程,包括胚胎的形成,脉管的分化,器官形成,向性运动和根系构造的形成。
Auxin and gibberellin, which are two of five classical plant hormones, play a very important role in regulating plant growth and development. 经典的五大类植物激素中的生长素(auxin)及赤霉素(gibberellin,GA)在植物生长的调节中起着非常重要的作用。
