双子叶植物

Since the plasmid is capable of independent replication in host cells of many dicotyledonous plants, it has been used as a cloning vector in GNETIC ENGINEERING.

在许多双子叶植物中质粒在寄主细胞中是独立的复制单元，所以可以在基因工程中用作克隆载体。

Dicotyledonous plants retain a series of strands.

双子叶植物中保留着一系列的束。

Rutaceae A family of dicotyledonous trees and shrubs.

芸香科：双子叶植物的一个科，乔木或灌木。

An order of dicotyledonous plants including Moraceae and Urticaceae and Ulmaceae.

双子叶植物的一个目，包含桑科、荨麻科和榆科。

Considered the most highly evolved dicotyledonous plants, characterized by florets arranged in dense heads that resemble single flowers.

被认为是双子叶植物纲中最高级的一种，其特点是花冠的大量浓密管状小花，看上去犹如一朵花。

Other leaf samples were collected from monocotylous and dicotyledonous plants, respectively to test this procedure. A series of PCR reactions were tested, which proved this method was widely acceptable.

以有代表性的单子叶和双子叶植物叶片为材料，经过多种内源基因PCR反应的反复验证，证实了这种方法的广泛适用性。

From above experiment results, we think that there may be no signal pathway for tomato systemin in the rice and, probably, signal transmission of injury in rice were other pathway different from dicotyledonous systemin.

据此试验结果推测，水稻中可能不存在类似于西红柿系统素的信号途径，很可能水稻的伤害信号转导是经由与双子叶植物系统素体系不同的其它途径来实现的。

In most dicotyledonous roots showing secondary growth.the pericycle is also involved in the origination of the vascular cambium and the phellogen.

在大多数双子叶植物根中有次生生长。中柱鞘也与维管形成层和木栓形成层的起源有关。

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。

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。
