单子叶植物的

The 9 species belong to 4 taxa, pteridophyta (Dicranopteris dichotoma and Alsophila spinulosa), gymnosperm (Cycas panzhihuaensis, Metasequoia glyptostroboides, Cunninghamia lanceolata and Pinus massoniana), dicotyledon (Schima superba and Cyclobalanopsis glauca), monocotyledon, which are ranked in the order of the origin time from earlier to later.

所选的9种植物分属于4个类群，按起源时间由早到晚依次为蕨类植物、裸子植物（苏铁、水杉、杉木和马尾松）、双子叶植物及单子叶植物。

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。

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。

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。

Orchidaceae is one of the largest families of monocot plants.

兰科植物为单子叶植物中最大的一个科。

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。

Petrosaviaceae are placed as a sister group of the dade comprising the Dioscoreales-Pandanales dade, Asparagales, Liliales and commelinoids.

无叶莲科Petrosaviaceae紧随广义的泽泻目之后分化出来，无叶莲科和剩余的单子叶植物类群形成姐妹群关系，并得到了较高的支持率。

Firstly, both cDNAs were isolated from the rice mature leaves using RT-PCR technique. By comparing their sequences with homologues from other plants, it was found that GME genes were highly conserved among plant species, though phylogenetic study showed that all known GMEs could be divided into two distinct groups corresponding to monocots and dicots.

通过逆转录PCR技术从水稻成熟叶片中克隆到两个GME基因的cDNA序列，并与其他植物物种中的GMEs进行比对，结果显示，GME基因在所有植物物种中高度保守，尽管进化树分析表明单子叶植物GMEs和双子叶植物GMEs在进化上相互独立。

Moreover, new vector systems and methods are developed to use in other plants, including monocots.

目前，VIGS体系应用最成功的植物是病毒学家常用的模式植物-本氏烟草，与此同时，也在努力改良VIGS技术，使其能够在包括单子叶植物在内的其它物种中得到广泛应用。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
