These research results suggested that this plant RNAi vector pCRiRRD3 can effectively perform gene silencing researches on both monocot and dicot plants.

这些研究结果表明，利用单子叶和双子叶双效活性的RRD3启动子而构建的植物RNAi载体，可同时有效地应用于大部分单子叶和双子叶植物的RNAi实验及研究。

The weeds in wheat field in the basin, river valley and plain area are generally taken as the main damage for agricultural crops. There is little difference of damage extent between dicotyledon and monocotyledon in mountain area and relatively low oasis plain.

盆地、河谷区域和平原区麦田杂草总体上以双子叶杂草为主；高海拔山地麦区以单子叶杂草为主；山地与海拔相对低的绿洲平原之间的过渡麦区，单、双子叶杂草危害程度基本相同。

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。

The results show that both of relative rate and synonymous and non-synonymous coden substitution in eudicot clade are significantly higher than those in monocot clade, and the value of dN/ds uncovered possible positive selective pressure in eudicot clade.

结果表明：真双子叶植物分支中SQUA类基因的相对速率和同义与非同义置换位点均显著高于单子叶植物分支；同时，dN／dS值表明真双子叶植物分支中可能存在正选择压力。

Using six monocotyledonous and dicotyldonous weeds and the plant shoots and soils as materials, all the compounds were tested indoors on the herbicidal activities. The results showed that one or two compounds have a definite herbicidal activity.

2所有化合物在室内分别对单子叶和双子叶的六种杂草，采用茎叶和土壤两种处理方法，进行了除草活性试验，结果有1—2个新化合物显示一定的除草活性。

Type and sole genus of the Clethraceae; deciduous shrubs or small trees: white_alder, summer-sweet.

桤叶树属的模式单属；双子叶的灌木或乔木。

Rubiaceae A large family of dicotyledonous trees, shrubs, and herbs, including some lianas, epiphytes, and ant plants (e.g. Myrmecodia).

茜草科：双子叶的植物的一个大科，为乔木，灌木或草本，包括一些藤蔓植物，附生植物和蚁树（茜草科 Myrmecodia ）。
