分生组织的

This work respectively studied the anatomical structure of shoot apices under a short-day photoperiod, a long-day photoperiod and a short-day―long-day photoperiod in the course of growing and developing.

在光学显微镜下观察，研究短日照、长日照、短日照-长日照处理的各个发育时期植株茎顶端分生组织的生长发育解剖结构变化。

The outer layer of apical meristem, from which the epidermis is formed.

表皮原顶端分生组织的外层，表皮就是从这里形成的

LjFLO has a possible role in maintaining the marginal meristem of compound leaf primordia.

LjFLO的功能可能与复叶原基边缘分生组织的维持相关。

The meristem cells arranged closly and there were rich plas-modesma between the cells.

在分生组织的区域，细胞排列紧密，细胞间存在丰富的胞间连丝。

The most critical events appeared to be the establishment of apical-basal patterns of symmetry,formation of apical meristems,and differentiation and axial change of procambium during the development of cotton somatic embryos.

棉花体细胞胚发育过程中最关键的事件似乎是极性的建立、顶端分生组织的形成以及前形成层的分化和生长轴变化。

Inaddition to that,LFY has a second role in the activation of the floral homeotic genes that specify the identity of organs in the flower and is a key intergrator of the outputs of floral inductive pathways.DFL, a FLORICAULA/LEAFY homologous gene,which cloned from C.lavandulifolium,was a key gene of florescence for C.lavandulifolium.

LEAFY基因在植物成花过程中意义重大，它不仅决定着花由营养生长向生殖生长的转变，它还接连GA成花途径和长日途径的信号继而诱导花分生组织的转变，同时还是活化花器官基因的关键基因。

The results showed that there was a great deal of microfilaments in root meristematic cells, there was a few microfilaments in cotton callus and abnormal plantlets; By alignment of PEAc17 with cotton actin.

我们发现在根原分生组织，原形成层和基本分生组织细胞中含有丰富的微丝，微丝呈网状分布；在愈伤组织细胞中微丝含量少；在畸形苗细胞中含有少量的微丝。

LjFLO has a possible role in maintaining the marginal meristern of compound leaf primordia.

LjFLO的功能可能与复叶原基边缘分生组织的维持相关。

Three major embryonic tissue systems,shoot apical meristem,root apical meristem,and the differentiation of procambial strands,were visible in torpedo-stage somatic embryo.

三种主要的胚性组织系统包括芽顶端分生组织，根顶端分生组织和原形成层束在鱼雷形胚阶段清晰可见。

LFY and LFY _like genes have been shown to control the initiation of floral meristems in higher plants.

LFY同源基因在高等植物花分生组织的发生中发挥着重要的作用。

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。
