细胞分裂

Variations were not only related to early regulation on the formation of flower organ subregions, but also to the changed rate of cell division.

其变异原因既与花器官亚区形成的早期调节有关，也与细胞分裂速度改变有关。

At lower concentrations they may even be stimulants of cell division .

在浓度较低时，它们甚至能促进细胞分裂。

The RER, which is studded with polysomes, also seems to be the source of the nuclear envelope after a cell divides.

糙面型内质网，镶嵌在多聚核糖体中，也可能是细胞分裂后核膜的来源。

Plasmids carry between 2 and 30 genes.

2在细胞分裂时可见多个。

Preliminary results indicate that NEK6 gene belongs to the NEK gene family and may function in the cell divisions.

结果初步显示，NEK6基因是哺乳动物NEK基因家族中的重要新成员，并可能在细胞分裂中发挥调节作用。

Applying B to the 2nd node of B deficient pea plants increased the IAA concentration and export from the shoot apex, and resulted in the establishment of apical dominance.

与此相比，对缺硼的豌豆植株第2节处供硼和CPPU后明显促进了侧芽的生长，说明细胞分裂素对侧芽生长的促进作用只有在供硼的条件下才能表现出来。

These include depolarization of the membrane potential in epidermal cells, specific expression of early nodulin genes and changes in the flux of calcium in root hairs, deformation of root hairs, cell division in the root cortex and formation of the nodule primordium.

结瘤因子信号能够诱导豆科植物根毛细胞质膜去极化、离子流动和早期结瘤素基因的表达以及根毛变形、皮层细胞分裂和根瘤原基形成等与共生有关的表型变化。

The four basic methods for estimating μ, frequency of dividing cells, biochemical indices, model approaches, and dilution incubations without grazers were reviewed, among them the dilution method was recommend as standard method for preliminary investigations of μ in China seas.

介绍和比较分析了研究μ的细胞分裂周期法、生物化学指示物法、模型法和去除摄食者稀释法这4类方法，推荐去除摄食者稀释法作为中国近海μ研究的重要方法。

New cells grow more slowly. Nonessentials—fingernails, toenails, hair—hardly grow at all.

新的细胞分裂速度减缓，那些不必要的——比如手指甲，脚趾甲，毛发几乎停止生长。

Mature and immature embryos of maize inbred line 87-1 were used as explants and calli were induced and cultured on improved N6 medium. The method of enzyme-linked immunosorbant assay was employed to detect endogenous contents of abscisic acid, indoleacetic acid, gibberellins (GA3) and cytokinins of immature, mature embryos and their calli during culture process.

以玉米自交系87-1的幼胚和成熟胚为材料，采用酶联免疫法测定了不同培养时间诱导的幼胚及成熟胚愈伤组织内源脱落酸、吲哚乙酸、赤霉素(GA3)和细胞分裂素含量的动态变化。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
