分生组织的

Macrocystis and Nereocystis and is distinguished by its heteromorphic ALTERNATION OF GENERATIONS in which a large sporophyte alternates with a microscopic gametophyte, and in which growth takes place in a special meristem region on the surface of the thallus.

在这类植物的生活史中，孢子体比配子体小。配子体是由叶状体表面特殊的分生组织区发育而来的。

New cells are cut off on the lower side to form new stem tissue at the stem apex, and on both sides in the root apex to form root tissue and a protective root cap.

顶端分生组织产生的新细胞沿根或茎的长轴方向排列，沿其长轴方向增加细胞的数目。

It shows that BTH and its metabolites have no immediate activity against pathogens and are in accordance with criterion of chemical elicitor.

组织病理学研究表明，BTH处理小麦后接种，并不抑制分生孢子的萌发和附着胞的形成，只是菌落的发展在很大程度上受到了抑制，表现为畸形附着胞数目增加、侵入率降低、侵入速率减小、菌落扩展速率减小、产孢率降低。

Furthermore, each developmental phase showed several different phases, these included inflorescence 0 phase, inflorescence Ⅰ phase, inflorescence Ⅱ phase; spikelet Ⅰ phase, spikelet Ⅱ phase, spikelet Ⅲ phase; palea primordium phase, lodicule primordium phase, stamen primordium phase and carpel primordium phase.

在这3个大的发育时期，又根据每一发育时期中的原基分生组织生长发育的程度及先后顺序分别又可分为：花序0期、花序1期、花序Ⅱ期；小穗期Ⅰ期、小穗Ⅱ期、小穗Ⅲ期；内稃原基分化期、浆片原基分化期、雄蕊原基分化期、心皮原基分化期。

These genes exact expression is activated by flower meristem identity genes and controlled by various positive and negative regulators.

这些基因的精确表达需要花分生组织特异性基因的激活和多个正负调节因子的调控。

WOX3 specifies the cell fate at the margins of cotyledonary primordia and regulates the rate of cell division in the margins of meristem in Arabidopsis.

阿拉伯芥的PRS/WOX3基因参与子叶原基边缘细胞专一性的决定，及调控分生组织边缘细胞分裂的速度。

Meristematic plants grow vigorously with a very uniform stand and reported yields are higher than those obtained with normal plants.

分生组织培养的植株生长茁壮、长势整齐，报导的产量高于一般植株的。

Plant growth and development are sustained by meristems.

植物的生长发育是依赖于分生组织实现的。

Unable to maintain root meristems. Our data showed that the defects in the mutant were related to the shift of the free histidine content in mutant plant.

虽然hpa1并没有显示出十分严重的组氨酸饥饿特征，但是在根的发育上表现出明显的缺陷，根部分生组织遭受严重破坏。

The relationship between MFs and MTs in the organization of PPB was investigated in garlic root tip cells subjected to treatment with cytochalasin D , latrunculin A and phalloidin .

用微丝特异性解聚药物（细胞松弛素CD和LAT A）以及微丝稳定药物处理大蒜根尖分生组织细胞的实验结果表明：微丝被破坏后，导致了早前期微管带宽度明显增加，Ph处理则对早前期微管带的宽度无影响。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
