Physiological and biochemical changes of monocotyledonous plant maize (Zea mays L.) were studied and the protective effects of nitric oxide against iron deficiency induced injury were analyzed simutaniously. The plants were grown in monofactor controlled solutions using solution cultural method and the full expanded fourth leaves were used in all of the experiments. The biochemical and the molecular mechanisms of iron induced injury and the protective mechanisms of NO against iron deficiency induced injury were studied.

本实验以溶液培养单因子控制方法研究了单子叶植物玉米在缺铁培养条件下结构、生理、生化的变化以及NO对缺铁植物的保护作用，发现了缺铁胁迫对植物损伤的生理生化及分子机理，以及NO在植物缺铁胁迫下对植物的保护机制，对于植物的缺铁研究和NO在植物中的保护机制研究都有极其的理论和实践价值。

The FLP/frt sitespecific recombination system fitting for monocotyledonous crops was constructed to breed the markerfree transgenic monocotyledons with high tolerance to salt and drought.

为培育去除选择标记基因的抗盐耐旱单子叶转基因植物，构建了适合于单子叶植物的FLP/frt位点特异性重组系统。

DNA C-values might be one of important indices in the evaluation of angiospermous invasiveness. To test this viewpoint, we compared DNA 1C-values and basic genome sizes in 3,676 angiosperms. The results suggest that:(1) the two nuclear values vary greatly among different groups, e.g., significantly higher in herbs than in trees, in monocots than in dicots, in perennials than in non-perennials;(2) the two nuclear values both have significant effects on plant invasiveness, especially in herbs, dicots, monocots, perennials, non-perennials, diploids, polyploids, Compositae, and Poaceae, while not significant in trees and Fabaceae.

DNA C值与被子植物入侵性密切相关，为考察应用DNA C值评估被子植物入侵性的可靠性和局限性，我们统计分析了全世界范围内3676种被子植物的DNA 1C值（配子未发生DNA复制时的染色体DNA含量）及基因组大小（单个染色体组的DNA 含量），结果表明：1）DNA 1C值和基因组大小在被子植物不同类群中差异极大，例如在草本植物中显著高于木本植物，单子叶植物显著高于双子叶植物，多年生植物显著高于非多年生植物；2）两项指标都与被子植物入侵性显著负相关，尤其是在草本植物、双子叶植物、单子叶植物、多年生植物、非多年生植物、二倍体、多倍体、菊科和禾本科中，然而在木本植物、豆科植物中其与植物入侵性无显著关系。

The members of it are distributed throughout the monsoon region of eastern Asia, with a single species of Croomia in the southeastern United States.

该科植物的雄蕊和花被片为4或5数，这在单子叶植物中非常特殊；叶为多变的网状脉；其中濒危植物黄精叶钩吻属为东亚-北美间断分布，呈现古老性。

In this review, we use Arabidopsis thaliana and Oryza sativa as examples, and summarize the study results of floral homeotic MADS-box genes in two major groups of angiosperms — core eudicots and monocots — over the past decade. Our aim was to review the functional conservation and diversity of floral homeotic MADS-box genes in angiosperms and discuss whether the ABCDE model has been conserved in monocotyledons.

本文以模式植物拟南芥和水稻为例，综述了近10年来对被子植物两大主要类群——核心真双子叶植物和单子叶植物花同源异型MADS-box基因的研究成果，分析MADS-box基因在被子植物中的功能保守性和多样性，同时探讨双子叶植物花发育的ABCDE模型在多大程度上适用于单子叶植物。

When the frequency of codon usage of citrus was compared to Homo sapiens, Drosophila melanogaster, Saccharomyces cerevisiac and Escherichia coli, we found that the codon preference is considerably different between citrus and non-plant species. While compared to Arabidopsis thaliana, Lycopersicon esculentum, Oryza sativa and Musa acuminata, we found that the codon preference was identical in dicotyledons, but was different between citrus and monocotyledon, Oryza sativa and Musa acuminate.

将柑橘的密码子使用频率与人、果蝇、酵母和大肠杆菌等不同种类模式生物比较后发现，柑橘密码子的偏爱性与不同种类生物有不同程度的差异；但将柑橘的密码子使用频率与拟南芥、番茄、水稻和尖叶蕉等不同种类的植物相比，发现柑橘密码子的偏爱性与同为双子叶植物的拟南芥、番茄完全一样，而与水稻、尖叶蕉这2种单子叶植物均有较大的差异。

Although the model doesn't suit to monocots, but it has helped to analyze new genes and gene functions in monocots. Although lilies are among the most important ornamental plants, relatively little research has been conducted on lily flower development.

虽然有证据表明依据拟南芥、金鱼草等双子叶植物提出的ABC模型，并不完全适用于单子叶植物，但是仍然给人们在单子叶植物花发育相关基因的克隆和功能研究中提供了参考和借鉴。

Two chloroplast, and one nuclear (18S) genes from 86 families, 126 genera, and 151 species of angiosperms (including 58 families, 86 genera, and 101 species of monocots), representing all major lineages of monocots and the basal angiosperms, were analyzed using parsimony methods.

基于两个叶绿体基因和一个核糖体基因(18S rDNA)的序列分析，对代表了基部被子植物和单子叶植物主要谱系分支的86科126属151种被子植物（单子叶植物58科86属101种）进行了系统演化关系分析。

Like most monocots, orchids generally have simple leaves with parallel veins, although some Vanilloideae have a reticulate venation.

就如同大部分的单子叶植物，兰科植物通常具有有平行脉的单叶，尽管一些香荚兰亚科植物具有网状叶脉。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
