It is continuous with the intrafascicular cambium.

在幼嫩的茎和根中，可看到原形成层进一步发育成束内形成层，后者的分裂活动产生了初生维管组织。

Companion cell An elongated thinwalled cell cut off longitudinally from the same meristematic cell as the SIEVE ELEMENT with which it is closely associated.

伴胞：与筛管分子侧面相邻的一种细胞，和筛管间有密集胞间连丝，它与筛管是由分生组织的同一个母细胞不均等分裂发育而成。

The appropriate combination and proportion of cytokinin and auxin played an important role in callus induction and bud differentiation of G.

结论］选用合适的细胞分裂素与生长素的组合及比例对非洲菊愈伤组织的诱导和芽分化具有重要作用。

Further analysis indicated that the value of CTK/IAA in decussate maize was not only dominant higher than in alternative maize, but also was increased accompanied with phyllotary changes from alternative to decussate.

对生叶序的形成与生长点组织细胞分裂素含量增加密切相关，玉米生长点CTK/IAA域值的稳定和变化是调节叶序稳定和变异重要因素。

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。

Embryoid stem cells are kinds of cell groups which are self-produce and differentiated into multi-oriental cell types.

The effects of 4-PU and 6-BA on formations of the calli and adventitious buds from epicotyl explants in peanut were studied in the experiment.

摘 要：以'汕油523'花生上胚轴为外植体，研究细胞分裂素4-PU和6-BA对愈伤组织诱导及不定芽发生的效应。

Neural cell adhesion molecule L1, discovered in the 80s, is one of the matters that can promote nerve regeneration. It can mediate the interaction of cell-to-cell and cell-to-matrix, take great efforts on neurite outgrowth and fasciculation, migration of neural cells, formation of the myelin, structure of neural trace, transmembrane signal transduction, inhibiting apoptosis of neural cells, even on immune system and formation of the tumor. Li is discovered on the mouse's Cerebellar membrane primarily. Thereafter, it also is found in post- mitotic neurons, pre- and non-myelinating Schwann cells and so on.

神经细胞粘附分子L1（L1）是80年代发现的具有促进神经再生作用的物质，它能介导神经细胞与神经细胞之间的粘附，在神经轴突的生长、聚集，神经细胞的转移，纤维髓鞘的形成，神经通路的构建及信号的转导，抑制神经细胞的凋亡甚至在免疫系统、肿瘤的发生等方面均具有非常重要的作用。L1最初是从小鼠的小脑膜中发现，后来发现在有丝分裂后的神经元，髓鞘形成前及非形成髓鞘的雪旺细胞等组织中同样存在。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .
