单子叶植物的

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。

Enzymatic activity assay of oxalate oxidase in transgenic tobacco plants indicated that the germ in gene from monocotyledon, could be expressed in dicotyledon tobacco plants that resu;ted in the formation of homopentameric protein with enzymatic activity correctly.

酶活性检测表明，源于单子叶植物小麦的germin基因能够在双子叶植物烟草中表达并正常装配成具有酶活性的同源五聚体蛋白。

Objective: To sexplore the anti-tumor activity to Hela, SW480 and A549 and the growth regulative activitiy to radishes of amphibrya besides corns of dicotyledon of the target compound γ-(N-p-methylphenylsulfonyl) aminopropyl-3, 7, 10-trimethyl-2, 8, 9-trioxa-5-aza1-1-silicontricyclo [3, 3, 3, 0(superscript 1,5)] Undecanes.

目的：探讨目标化合物γ-丙基－3，7，10-三甲基－2，8，9-三氧杂－5-氮杂－1-硅杂三环[3，3，3，0(上标 1，5)]十一碳烷对人宫颈癌细胞、人结肠癌细胞(SW480)和人肺腺癌细胞(A549)的抗肿瘤效应以及对单子叶植物玉米、双子叶植物萝卜的生长调节作用。

Only dicotyledonous flowering woody plants and most gymnosperms have true twigs; monocotyledons and tree ferns do not.

只有双子叶的木本开花植物和大部分的裸子植物才有真正的小枝，而单子叶植物和树蕨类植物则没有。

Cereals and grasses are generally resistant, while dicotyledonous plants are often very susceptible.

具有狭长直立叶子的单子叶植物对它具有普遍的抗性，而有些双子叶的植物则对它敏感。

Gunckel, who on the evening card ginkgo auxin from the stem end is not at Health Organization, or young leaves, and some Monocotyledon similar, from a rib-like sub-section of the Health Organization.

Gunckel等人的研究证晚银杏生长素不是来自茎端分生组织或幼叶，而与某些单子叶植物相似，来自具肋状分生组织的节间。

Siltp expresses in stem, leaves and grains. Using software PAUP to analyze evolution of LTP from 17 different plants, phylogenetic tree allows the conclusion that LTP has four groups. Differentiation happened earlier in wheat,while in the other monocots such as maize, millet,barley and rice happened later.

利用软件PAUP对17种植物的LTP进行进化分析，从进化系统树可以看出LTP有4个分支，其中，小麦发生分化较早，其它几种单子叶植物如玉米、谷子、大麦和水稻分化较晚，说明发生了早期的基因复制事件。

Compared with the dicot, the monocots preferred GC-rich tri- and hexa- motifs very much, especially in rice where 23.6 CCG motif occurred in 100kb ESTs.

与双子叶植物大豆相比，单子叶植物似乎更偏好富含GC的三碱基和六碱基重复单元，特别是水稻中平均每100kb EST就有23.6个CCG类型的SSR出现。

Rice (Oryza sativa L.) is not only one of the most important food crops in the world,but also a model plant for study of molecular developmental biology in monocots.

水稻是世界上最重要的粮食作为之一，也是单子叶植物发育生物学研究较理想的模式植物。

In conservative families, there has been little or no change in the number of genes since the divergence between eudicots and monocots ~145 million years ago.

在保守的家族中，基因的数目在大约一亿四千五百万年前(~145MYA)真双子叶植物和单子叶植物发生分化之后都没有改变或者变化甚微。

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。
