植物园发展的动向

对国内外植物园近十余年来发展的动向进行评述,列举了近年来一系列重要的植物园国际会议与重大活动,指出当前国际植物园工作的中心任务首先是物种保护。总结和分析我国植物园发展的历史和现状、存在问题以及在园貌建设上与国际先进植物园的差距。这些差距主要表现在：（１）植物的收集量;（２）活植物数据的积累;（３）罕见植物的引种;（４）现代技术的应用。作者最后提出,我国植物园发展应把握的几个主要问题是：（１）既是多功能全方位发展,又应各具特色;（２）生物多样性是植物园永恒的主题;（３）植物园应着重物种迁地保护的研究和实践;（４）植物园应重视栽培和利用植物并着重以药用植物为对象。     

体验自然的课堂——辰山植物园的科普教育

科普教育工作是实现植物园职能的重要组成部分,国内外众多植物园都把科普教育作为一项重要的工作来抓,植物园现已逐步发展成为满足公众种植爱好、提高公众科学素养、培养公众生态保护意识的重要基地。辰山植物园作为新建植物园,在园区规划和     

美国植物园的科普教育

科普教育是植物园最具生机的活动。通过普及植物学和园艺学知识,可以唤起人们对大自然的追求和崇尚之情,提高民众热爱和保护人类生存环境的意识,由此产生的社会效益是无价的。笔者不久前曾去美国多座植物园考察和访问,对美国植物园在开展科普教育活动方面做的出色工作,深有感触。门）科普办公室目前美国有312座植物园（包括树木园）,几乎各园都设有科普办公室,负责组织安排科普活动,印刷科普小册子和活页资料,无偿向游人提供。科普活动计划按季节提前印刷成文,详细列出活动项目、内容、讲授人或导游者、时间、地点、费用等,让参…     

面对21世纪的中国植物园

在总结中国植物园发展历史及当前国际植物园发展趋势的基础上,论述了中国植物园面对对世纪所必须重视的5个方面。（1）植物园整体质量和特征化,作者列举了10个方面的差距。（2）药用植物的栽培、利用和保护。从药用植物分类学研究,有效成分的分析及动态研究,药用植物栽培化和“地道药材”问题4个方面论述植物园的优势和潜力。阐明了“栽培化”的涵义。（3）引种和物种保护,指出广泛引种的重要性和重点种类迁地保护的必要性,并首次提出了“濒危生境”这个术语及其概念。指出了未来引种理论研究的方向及其对农业生产的意义。（4）活植物收集圃信息系统。（5）科普教育。作者认为,虽然不少植物园目前还面临着或多或少的困难,但就整体而言,未来的10年将是植物园继续较大发展的10年。

数字化植物园的理论与技术思考—以华南植物园为例

植物园是通过人工模拟区域自然环境和群落结构,实现物种多样性高度富集并进行相关科学研究的机构,也是生物多样性保育、科普教育、资源储存和开发利用的基地。随着信息技术的发展及其在植物园中的应用,将产生数字化植物园。在研究数字化植物园发展历史的基础上,提出广义和狭义的数字化植物园定义,并以华南植物园的数字化建设内容为例,探讨了数字化植物园的信息技术体系、虚拟植物和专类园智能化管理技术等理论与技术体系结构。

Recent advances in the study of Kaposi's sarcoma-associated herpesvirus replication and pathogenesis

It has now been over twenty years since a novel herpesviral genome was identified in Kaposi's sarcoma biopsies. Since then, the cumulative research effort by molecular biologists, virologists, clinicians, and epidemiologists alike has led to the extensive characterization of this tumor virus, Kaposi's sarcoma-associated herpesvirus(KSHV; also known as human herpesvirus 8(HHV-8)), and its associated diseases. Here we review the current knowledge of KSHV biology and pathogenesis, with a particular emphasis on new and exciting advances in the field of epigenetics. We also discuss the development and practicality of various cell culture and animal model systems to study KSHV replication and pathogenesis.     

A Unique Protease Cleavage Site Predicted in the Spike Protein of the Novel Pneumonia Coronavirus (2019-nCoV) Potentially Related to Viral Transmissibility

正Dear Editor,In December 2019, a novel human coronavirus caused an epidemic of severe pneumonia(Coronavirus Disease 2019,COVID-19) in Wuhan, Hubei, China(Wu et al. 2020; Zhu et al. 2020). So far, this virus has spread to all areas of China and even to other countries. The epidemic has caused 67,102 confirmed infections with 1526 fatal cases     

Curcuminoids as inhibitors of thioredoxin reductase: A receptor based pharmacophore study with distance mapping of the active site

Curcumin is the yellow pigment of turmeric that interacts irreversibly forming an adduct with thioredoxin reductase (TrxR), an enzyme responsible for redox control of cell and defence against oxidative stress. Docking at both the active sites of TrxR was performed to compare the potency of three naturally occurring curcuminoids, namely curcumin, demethoxy curcumin and bis-demethoxy curcumin. Results show that active sites of TrxR occur at the junction of E and F chains. Volume and area of both cavities is predicted. It has been concluded by distance mapping of the most active conformations that Se atom of catalytic residue SeCYS498, is at a distance of 3.56 from C13 of demethoxy curcumin at the E chain active site, whereas C13 carbon atom forms adduct with Se atom of SeCys 498. We report that at least one methoxy group in curcuminoids is necessary for interation with catalytic residues of thioredoxin. Pharmacophore of both active sites of the TrxR receptor for curcumin and demethoxy curcumin molecules has been drawn and proposed for design and synthesis of most probable potent antiproliferative synthetic drugs.     

The structure, reproduction and taxonomy of Vidalia and Osmundaria (Rhodophyta, Rhodomelaceae)

Comprises species occurring mostly in subtidal habitats in tropical, subtropical and warm-temperate areas of the world. An analysis of the type species, V. spiralis (Sonder) Lamouroux ex J. Agardh, a species from Australia, establishes basic characters for distinguishing species in the genus. These characters are (1) branching patterns of thalli, (2) flat blades that may be spiralled on their axis, (3) width of the blade, (4) primary or secondary derivation of sterile and fertile branchlets and (5) position of sterile and fertile branchlets on the thalli. Application of the latter two characters provides an important basic method for separation of species into three major groups. Osmundaria , a genus known only in southern Australia, was studied in relation to Vidalia , and its separation from the Vidalia assemblage is not accepted. Species of Vidalia therefore are transferred to the older genus name, Osmundaria. Two new species, Osmundaria papenfussii and Osmundaria oliveae are described from Natal. Confusion in the usage of the epithet, Vidalia fimbriala Brown ex Turner has been clarified, and Vidalia gregaria Falkenberg, described as an epiphyte on Osmundaria pro/ifera Lamouroux, is revealed to be young branches of the host, Osmundaria prolifera.     

New or rare chromosome counts in Artemisia L. (Asteraceae, Anthemideae) and related genera from Kazakhstan

Fifteen chromosome counts of six Artemisia taxa and one species of each of the genera Brachanthemum, Hippolytia, Kaschgaria, Lepidolopsis and Turaniphytum are reported from Kazakhstan. Three of them are new reports, two are not consistent with previous counts and the remainder are confirmations of very scarce (one to four) earlier records. All the populations studied have the same basic chromosome number, x = 9, with ploidy levels ranging from 2x to 6x. Some correlations between ploidy level, morphological characters and distribution are noted.
