分生组织的

The primary cambium is found in the stem and root between the phloem and xylem cells, and by division gives rise to the secondary phloem and xylem in woody dicotyledonous plants.

它纵贯于根，茎等器官的木质部和韧皮部之间，是具有分生能力的组织。通过形成层的分裂可以在木本的双子叶植物中形成次生木质部和次生韧皮部。

With tile ovary maturing, the orifice was narrowed because of tile ovary growth at last fused completely. The gynoecium is composed of a single carpel.(1) In tile series developmental sections of ovary, the ovular primordium was initiated on the adaxial meristem when tile mouth of ovary was formed.

子房由1枚心皮构成；(4)从子房发育过程的切片看，该植物的胚珠是在子房发生后不久发生的，子房上的圆孔形成时，从近轴侧的分生组织发生胚珠原基，由胚珠原基分化出珠被与珠心。

The RNA in situ hybridization experiments revealed that MOC1 was initially expressed in a few epidermal or subepidermal cells in the leaf axil prior to the formation of axillary meristem.

另外，我们发现在moc1突变体中由于MOC1基因的功能缺失突变，导致了分生组织特异性的OSH1基因和控制侧枝伸长的OSTB1基因的表达水平降低。

The increase ofIAA concentration regulated the expression of cyclAt gene,and subsequentlypromoted the division of meristematic cells and thus speeded up the extension ofroots.

根部生长素浓度的变化诱导了cyclAt基因的表达，促进了根分生组织细胞的分裂，加速了根的伸展。

When pea ( Pisum sativum L.,Alaska strain) was grown in short\|day conditions,the apical bud senescence started with the transformation of the bud from vegetative to reproductive growth.DNA fragmentation was detected during the senescence using the terminal deoxynucleotidyl transferase\|mediated dUTP nick end in situ labeling method.The cell ultrastructural changes were similar to apoptosis in animal cells:the apical meristemetic cells underwent the programmed cell death.This wa...

显微、超微结构研究表明，短日照条件下豌豆顶芽的衰老过程是从营养生长锥向花芽的转化，而用DNA原位末端标记、Caspase 8WesternBlot和 14 0bpDNA片断积累的试验结果证明，转化为花芽的整个生长锥细胞发生了编程性死亡，而且其最顶端部分细胞首先发生PCD ，而顶端周围的分生组织细胞逐渐分化出花芽的各部分，但顶芽最后并没有发育成为完整的花，所有细胞就都发生PCD ，从而顶芽衰老

Commassie brilliant blue staining can clearly display the different structures of Sphaerotheca fuliginea, such as germinating conidia, initial germtubes, hyphae and conidiophores, and hardly stain the host tissue, presenting a striking contrast between fungus and host tissue.

考马斯亮蓝组织透明染色方法可以清楚观察到白粉病菌的5个发育阶段，即萌发的分生孢子、初生芽管、胞间菌丝、分生孢子梗和后期菌落。考马斯亮蓝几乎使寄主组织不着色，不产生背景色干扰，而菌体变深蓝色。

In functional study, overexpression assay was conducted in potato. Interestingly, tuberous swelling along roots was observed in some transgenic potato lines in addition to stem-derived tuber formation. Conclusively, we propose a hypothesis to illustrate the mechanism by which IbMADS1 participates in the initiation of tuberization in sweet potato.

利用解剖切片观察并比较转殖马铃薯与野生型甘薯的根部块状膨大区域，可以发现两者在膨大初期，中柱内含的细胞数皆增多，尤其是木质部细胞出现不正常增生情形，进而扩展中柱区域；因此，我们可以初步推论在甘薯块根发育初期，IbMADS1藉著作用於根部分生组织，尤其是中柱的原始形成层，从而促进细胞分裂，并参与甘薯的初期结薯。

Raunkiaer's classification of life forms is based on the vulnerability of plant meristems to frost.

朗基耶尔的生活型分类就是建立在植物的分生组织对霜冻适应脆弱性的基础之上的。

Of a species and an isotherm. Raunkiaer's classification of life forms is based on the vulnerability of plant meristems to frost.

朗基耶尔的生活型分类就是建立在植物的分生组织对霜冻适应脆弱性的基础之上的。

Frequencies of multipolar division cells and bridges lagging chromosome were 0.08% and 0.434% respectively when root meristems were treated with 3-4 μmol/L APM.

在3~4μmol/L浓度下处理的根尖分生组织细胞中，多极分裂细胞的出现频率为0.08%；染色体桥、断片和滞后染色体的出现频率为0.434%。

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。
