双子叶植物

It can infect more than one thousand two hundreds monocotyledon and dicotyledon transmitted by aphides or mechanical transmission and brings tremendous disaster to agriculture.

CMV是世界性分布范围最广、发生最普遍的植物病毒之一，可由蚜虫和机械方式传播，侵染100科1200多种单、双子叶植物，对农业生产危害较大。

dicotyledonous plant for the flower species of the Asteraceae family coltsfoot.

为双子叶植物药菊科植物款冬的花蕾。

Agrobacterium A genus of soil bacteria, the species A. tumefaciens being the causative agent of CROWN GALL, a type of tumor in plants.

根癌农杆菌：土壤中存在的一种农杆菌，可以感染双子叶植物的受伤组织诱发一种植物的肿瘤－冠瘿瘤。

At present, most genes were isolated by screening the cDNA or DNA library with theprobes homologous to sequences of dicot plants, and their functions were identified by themorphology of floral organs in transgenic plant.

目前研究手段主要是利用双子叶植物的同源序列来筛选水稻的cDNA文库，获取相关基因，然后根据转基因植物花器官的表型来验证该基因的功能。

In this study, the splicing patterns of gene fragments derived from monocot rice BADH2 and dicot Arabidopsis GR7 were detected by Agrobacterium-mediated tobacco transient expression system.

本研究利用农杆菌介导的烟草瞬时表达系统分别对单子叶植物水稻BADH2和双子叶植物拟南芥GR7基因片段在烟草叶片中的转录后剪接加工进行分析。

However, the homology between rape and tobacco is obvious higher than that between rape and rice, probably infering the closer phylogenetic relationship between dicots than that between a dicot and a monocot.

推导的氨基酸序列在三种植物之间的同源性也很高，但总的来看，油菜与烟草之间明显高于油菜与水稻之间的同源性，反映出单、双子叶植物之间亲缘进化关系的不同。

Plating method test was used to examine its growth regulative activity on radishes of amphibrya and corns of dicotyledon.

将目标化合物用水配制成浓度分别为10ppm、50ppm和100ppm的溶液，采用平皿法测试目标化合物对单子叶植物玉米和双子叶植物萝卜的生长调节作用。

The concentration of the compound was prepared as 10, 50, 100 ppm using water. plating method test was used to examine its growth regulative activity on radishes of amphibrya and corns of dicotyledon.

将目标化合物用水配制成浓度分别为10 ppm、50 ppm和100 ppm的溶液，采用平皿法测试目标化合物对单子叶植物玉米和双子叶植物萝卜的生长调节作用。

These results show that codA gene cloned from E. coli can express specifically in the anther of both monocotyledon and dicotyledon plant species upon induction of 5-FC, and the in vivo expression product of the gene can transform the 5-FC used externally into 5-FU, which leads to all or partial inactivity of anthers and/or pollens.

以上结果表明，codA基因在单子叶植物和双子叶植物花药中的特异性表达，能将外用的5-FC在体内转化为5-FU，导致花药或花粉的部分和全部失活。

The results of phylogenetic analysis showed that DFR from Hyacinthus orientalis and from Iris x hollandica clustered together firstly ,and then came those from other monocotyledon, dicotyledon came subsequently.

聚类分析表明，最先与风信子聚类合并的是鸢尾，其次与其它单子叶植物聚类，最后与双子叶植物聚类。

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。
