ARR4 responded to cytokinins at early time of seed germination, especially on the 6 d when seedlings were around true leaf initiation, while cyto- kinins induced ARR5 activation after 6 d of seed cul- tivation in light conditions, an obvious increase was on the 20 d when seedlings were around inflorescent shoot initiation.

在双组分信号传导途径中，从受体到反应调节基因传导磷酸基团的传导基因AHP4在幼苗发育的后期种子萌发后的第20和30天，应答植物体内增加的植物细胞分裂素，并且在花枝形成初期比较明显。

In this paper, we studied seasonal variation of endogenous IAA、 GA_3、ZR and ABA content of Leymus chinensis、 Agropyron michno、 Stipa grandis、 Cleistogenes sguarrosa、 Koeleria cristata、 Carex korshinskyi、 Allium bidentatum、 Artemisia frigida, Kochia prostrate and Potentilla acaulis in different restoring succession stages, which were determined by ELISA in the growing season in 2005. At the same time we recorded the phenological development and growing regulation of each kind of plant.

本文于2005年生长季，对处于不同恢复演替阶段的羊草、米氏冰草、大针茅、糙隐子草、草、黄囊苔草、双齿葱、冷蒿、木地肤和星毛委陵菜十种植物，运用酶联免疫吸附法，测定内源生长素、赤霉素(GA_3)、细胞分裂素和脱落酸含量的季节动态，同时记录每种植物的物候期和生长规律情况。

"Other types, known as lysogenic or temperate , integrate their nucleic acid into the host's chromosome to be replicated during cell division."

其它种类(称潜溶性噬体或温和性噬体)会将核酸植入宿主的染色体内，以在细胞分裂中复制。

From the study, we conclude that bFGF has the differentiative, migrative and mitogenic functions in the developing chick neuroretina.

由本实验中，我们推论在鸡胚神经网膜层发育期间，bFGF具有分化、移行和细胞分裂的功能。

The result showed that the main factors of multiplication of bud clumps are the basic medium, BA and NAA.

结果表明：影响丛生芽增殖的显著因子分别是基本培养基、细胞分裂素BA、生长素NAA。

No callus could be induced from leaf or petiole explants of varieties F30 and Ⅱ cultured on MS medium if supplemented alone with 6-bezyladenine （6-BA） or thidiazuron, or kinetin. However, the calli were induced on MS medium containing 2.0 mg L-1 6-BA and 0.5 mg L-1 NAA （α-naphthaleneacetic acid）, and the calli derived from petioles of variety Ⅱ could produce redifferentiated shoots, but of variety F30 could not. The later could only produce shoots directly from the base of the petioles.

将品种F30和Ⅱ的叶片和带叶叶柄接种到含不同浓度单一细胞分裂素（6-BA、TDZ、KT）的MS培养基上培养，均未能诱导出愈伤组织，而在含2.0mgL-1 6-BA＋0.5mgL-1 NAA的培养基上可以诱导出愈伤组织，且由品种Ⅱ叶柄诱导产生的愈伤组织可再分化出芽，品种F30诱导的愈伤组织却不能分化，但在其叶柄基部可直接出芽。

Results: hALP distributed predominantly in the nucleoli of HeLa and Saos2 cells, and colocalized with rDNA.

结果：hALP在HeLa及Saos2细胞分裂间期主要定位于核仁，并与rDNA有共定位。

Application of EBR induced parthenocarpic growth accompanied with active cell division in Jinchun No.4, a cultivar without parthenocarpic capacity, whereas Brz treatment inhibited fruit set and subsequently fruit growth in Jinchun No.2, a cultivar with natural parthenocarpic capacity, and this inhibitory effect could be rescued by application of EBR.

在非单性结实的津春4号黄瓜栽培品种的子房上添加EBR可以诱导单性结实并且提高细胞分裂能力，而在单性结实的津春2号黄瓜栽培品种的子房上喷施BRs合成抑制剂抑制果实生长，最终导致败育，而这种抑制现象可以通过添加EBR得以恢复。

Boron is one of the essential nutrients for plants and B deficiency induces a series of physiological changes, including the release of lateral bud. In the present study, the mechanism about the B deficiency-induced apical dominance was studied in pea plants Pisum sativum L.

cv。 Lisa为主要试验材料，研究缺硼减弱顶端优势和诱导侧芽生长的机理、生长素和细胞分裂素在顶端优势中的重要作用以及两者之间的相互作用。

Many researches show that organism activity gene plays an important role in regulating the mechanism of injury and plerosis of articular cartilage.

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。
