auxin

Endogenous auxin is often distributed asymmetrically throughout the plant, accumulated in certain tissues and cells.

生长素的极性运输导致其积累在某些局部组织和细胞内，形成特定梯度分布。

Researchers have known since the nineteen thirties that the actively growing tip of a plant releases a hormone called auxin.

从十九世纪三十年代，研究人员已经知道植物活跃的生长锥释放一种称之为auxin的荷尔蒙。

An auxin increases the growth in length of a plant cell, thus causing the curving of a stem, or roof, in phototropism and geotropism.

植物生长素能加快植物细胞长势，因此使茎弯曲向着阳光，或使根深扎入土。

It is inconsistent to attribute such a short lag period to a result of an auxin effect on gene activity.

将如此短暂的延迟期归结为生长素作用于基因活性的结果走不合适的。

For long-term tissue cultures of domestic carrot the only requirement for adventive embryogeny was addition of an auxin.

栽培的胡罗卜进行长期组织培养时，对不定胚发生的唯一要求是加进植物生长素。

Phytohormones, especially auxin, play essential roles in coordination of these two regulation mechanisms.

植物激素，尤其是生长素在协调体内外调节机制中起着不可或缺的作用。

Researchers have known since the 1930s that the actively growing tip of a plant releases a hormone called auxin.

研究者自上个世纪30年代就已经知道植物活跃生长的尖端产生一种名为生长素的激素。

When the top of the main shoot is removed -- by pruning or breakage -- the auxin is no long produced.

当主芽的顶端被修剪或受到损坏时，将不能再分泌生长素。

Auxin is now known to be a key regulator of polar events in plant cells.

生长素是目前已知的一个关键调节极性事件的植物细胞。

Normally, the T-DNA region contains genes for auxin and cytokinin biosynthesis and for amino acid and sugar derivative production.

通常T-DNA区都含有生长素和细胞分裂素合成基因以及氨基酸和糖类衍生物合成基因。

Differentiation to form roots, shoots and plantlets can be induced by selecting an appropriate auxin: cytokinin ratio for the medium.

通过配置培养基中生长素和细胞分裂素合适的比例可以诱导分化形成根、茎和小植株。

You must be auxin, cause you are causing me to have rapid stem elongation.

你一定是生长素，因为你让我的茎迅速的延长。

The function of IAA in plant growth was introduced systematically. The progress of polar auxin transport mechanism was discussed.

通过了解生长素在植物生长发育中的作用，进而阐述生长素极性运输机理方面的研究进展。

In this article I suggest instead that the polar signal is the auxin gradient within the cell cytoplasm.

在本文中，我建议的极性相反的信号是生长素梯度细胞质内的细胞。

However, the effect of auxin on those indexes decreased with the time of adding auxin after the middle leaf maturity.

试验还证明，中部叶成熟后，生长素的效果随涂抹时间的延长而逐渐减弱。

Cytokinin is known to have negative effects on denovo auxin-induced root formation.

细胞分裂素对生长素诱导的根的形成具有负向作用。

Meanwhile, adding auxin could provide enough energy for absorbing nutrients for roots by increasing the amount of ATP.

同时能提高根系ATP的含量，为根系吸收养分提供充分的能量保证。

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。

This implies that node 1 may be the location where a possible interaction between auxin and D10 gene would be detected.

这一结果暗示第一节可能是可以检测到D10基因和生长素发生相互作用的部位。

Scientists say the auxin has an indirect effect on buds on the side of the stem to prevent branching.

科学家们称生长素可以间接作用于植物侧面的叶芽，以阻止其分枝。
