植物生物学

Nowadays, the nomenclature and taxonomy based on Linnaean system, though has a history of over 250 years, are still predominant among taxonomists, and the following international nomenclature codes of zoology, botany and bacteria have run its way for about 100 years and are keeping on revising.

基于林奈命名法和林奈分类系统的生物分类系统已经存在250多年并仍然为广大生物学工作者使用，由此产生的国际动物、植物、细菌的命名法规亦执行了100年（1905年，国际植物命名法规第1版产生），并在不断修订。

The result showed that the polarization of populations and gene fluxes are different in different species. The polarization and gene fluxes of populations of 3 Nitavias are lower except N. sphaerocarpa. The heredity coherence of each population is change from 0.8561 to 0.9694. The polarization in the populations is low, and they have the together ancestor. This is similar to morphology and cytology result, so RAPD is a useful supple mentary method in assessing genetic relationship among Nitraria species.

结果表明：白刺属植物的遗传分化程度和基因流因种而异，除球果白刺以外，其余3种白刺的种群间有很大的基因流，其遗传一致度在0.8561~0.9694之间，而种间遗传分化程度较低，故4种白刺有着相近的祖先，这与形态学和细胞学的分析结果一致，说明RAPD分析方法可从分子生物学角度为白刺属植物的系统学分类提供更为有利和可靠的证据。

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。

The study of the biological characteristics of resistant phytopathogenic fungi has great theoretic and practical significance for improving the strategy of chemical pesticide application, postponing the occurrence of the resistance and advancing the chemical prevention and control of diseases caused by phytopathogenic fungi.

研究植物病原真菌抗药菌的生物学特征以及它们的抗药机制对于改进化学农药使用策略，延缓抗药性的产生，推进植物病害的化学防治，具有十分重要的理论和实践意义。

Belong to abroad floral to study progress and the application on medicine make one overview to nettle now. 1 nettle belongs to floral biology character to reach distributinging nettle Urtica Spp.

现将国外对荨麻属植物的探究进展及在医学上的应用作一综述。1荨麻属植物的生物学特性及分布荨麻Urtica spp。

Moreover, because the mulberry is a cross-pollinated plant, it is hard to judge the relations among the species accurately because of the hard up for phylogenetic information in transition types formed in intra-species and inter-species hybridization, therefore, there is no satisfied classification method for Morns L..

因此，利用分子生物学技术研究桑属植物的系统与进化关系，有助于解决我国桑属植物分类中所存在的问题，对于桑树种质资源的分析、鉴定和利用、桑树的遗传育种都具有十分重要的意义。

The criteria for woody ground cover plants were summarized as, low height, easy ramifying, strong adaptability, easy propagating, and good colony expressive force. There are abundant woody ground cover plants resources, including creeping shrubs, low shrubs, low bamboos and woody climbers in China, but only a few species are used in landscaping, and it is short of researches in biological characteristics and landscaping design.

木本地被植物应当具有植株低矮、易分枝、适应性强、繁殖容易、群体表现力好的特点；我国具有丰富的木本地被植物种类，可以分为匍匐灌木、低矮灌木、地被竹和木质藤本4类，但目前园林中应用的种类较少，而且对其生物学特性和配置方式缺乏研究。

Fossil woods, silicified and charcoal material, are investigated for the first time from the Yuanmou Basin of Yunnan Province and the Taigu Basin of Shanxi Province at the age of Pliocene in present paper.

首次报道了云南元谋盆地(虎跳滩土林、湾堡土林和新华土林)晚上新世的硅化木材植物群和山西太谷盆地晚上新世的炭屑木材植物群，分析了这两个盆地当时的植被、环境和气候，为认识我国西南地区和北方中部地区晚上新世气候变化提供了生物学证据。

At same time,studies have much progress in classification and identification of endophytes,especially after the application of molecular biology techniques in it.

与此同时，植物内生菌分类鉴定的研究也有一定的进展，特别是在分子生物学技术应用到其中后。基于这点，就最近10年来有关植物内生菌分类鉴定的文献所使用的技术进行了分析和讨论。

GA promotes plant growth via 26S proteasome-dependent proteolysis of DELLA proteins repressors, one of the key component in GA signaling, and also depends on GA-mediated interaction between GA receptor and DELLA proteins. Finally, this paper discussed the cross-talking between GA and other hormones, and modulation of adaptation to environments.

本文综述了赤霉素生物合成的生物学途径及其调控研究； GA信号转导通道的研究进展，特别是DELLA蛋白阻遏植物生长发育的分子机理和GA解除阻遏作用的分子模型； GA受体研究的新进展；探讨GA与其它激素之间的相互作用，以及植物在应答环境过程中的作用。

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。
