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。

In this article, the domain structure of LBD genes, classes of LBD genes in model plants of monocotyledon or dicot, expression model, mutation phenotypes from loss of function or gain of function, and its relationship to other gene families were reviewed. Furthermore, the redundancy character of LBD genes, basic candidate function shared by LOB domain, and potential molecular mechanism of LBD genes interacting with other genes also were discussed.

本文对LBD基因的结构域特征、在单／双子叶模式植物中的分类、表达特点、己克隆LBD基因的功能及与其它基因或基因家族间的相互作用关系进行了综述，并对LBD基因在高等植物中的功能冗余特性、LOB结构域可能所具有的基本功能和LBD基因与其它基因相互作用的分子机制进行了探讨。

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。

Analyzing T-DNA flanking sequences isolated by TAIL-PCR revealed that the T-DNA nick position in the tagged rice plants are more complex than in tansgenic dicot species as tobacco and Arabidopsis.

分析TAIL-PCR分离的T-DNA侧翼序列，发现水稻转化体中T-DNA右边界的剪切位点比转基因拟南芥和烟草等双子叶植物中T-DNA右边界的剪切位点要复杂得多。

During the latest fifteen years a great progress has been achieved on transgenic research of the main crops including soybean, maize, rice, and wheat. Almost all the transformation techniques have been successfully used in these main crops. Especially for the Agrobacterium mediated transformation, not only successes it in soybean, a recalcitrant dicot plant to transformation, but also in rice, maize and wheat of monocot plants.

近15年来，大豆、水稻、玉米、小麦等主要农作物转基因研究取得了较大进展，几乎各种遗传转化方法在这些作物上都取得了成功，尤其是农杆菌介导法，不仅在难转化的双子叶作物大豆上取得了成功，而且在单子叶作物水稻、玉米、小麦上先后取得了突破。

Tea tree is a kind of very old dicotyledon, closely related the life with people.

茶树是一种很古老的双子叶植物，与人们的生活密切相关。

The one division of the dicotyledon.

双子叶植物的一科。

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。

Wheat PGIP was deglycosylated using TFMS, and the result indicates that carbohydrates content is 22%, which is consist with PGIPs from dicotyledon.

用TFMS将小麦PGIP去糖基化，结果表明小麦PGIP的糖含量为22％，与双子叶植物PGIP相似。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
