基于文献计量分析的植物多倍体诱导研究进展

Research progress of plant polyploidy induction:A bibliometric analysis

为全面了解植物多倍体诱导相关研究现状和前沿发展趋势,更好地把握最新的研究动态,本研究分别对2000-2020年收录在中国知网(China National Knowledge Internet,CNKI)和Web of Science核心合集数据库(WOS)中有关多倍体诱导的文献,从发文趋势、被引频次、国家、期刊、机构、关键词、突现词等多角度检索后进行系统性分析。分析结果显示:就植物多倍体诱导这一研究领域而言,以中国、美国、日本贡献最为突出,其研究大多侧重于多倍体诱导与鉴定方法;从相关研究机构角度分析,以北京林业大学(Beijing Forestry University)发文数量最多,远超其他机构;而在发文期刊中,《Euphytica》处于领先地位。基于全球尺度下关于多倍体诱导的研究成果,综合分析该领域热点和前沿,今后的研究将致力于解决如下问题:1)统一多倍体诱导率的评估程序;2)解决诱导过程中出现的嵌合体问题;3)深入了解多倍化后基因组变化与新表型表达之间的关系。

To comprehensively understand the current research status and frontier development trends in plant polyploid induction and to obtain a better understanding of the latest research trends,we collected data from China National Knowledge Infrastructure(CNKI)and Web of Science(WOS)from 2000 to 2020.The literature on polyploid induction was systematically analyzed in terms of publication trends,frequency of citations,countries,periodicals,institutions,keywords,and burst terms.The analysis results show that in the research of plant polyploid induction,China,the United States,and Japan have made the most outstanding contributions.Most of this research focused on polyploid induction and identification methods.Of all the research institutions,Beijing Forestry University has the largest number of publications by far.Among these publications,“Euphytica”is in a leading position.Based on the research results of polyploid induction on a global scale and a comprehensive analysis of the hotspots and frontiers in this field,future research should focus on solving the following problems:1)standardizing the evaluation procedure of polyploid induction,2)solving the mosaic phenomenon during induction,and 3)achieving an in-depth understanding of the relationship between genome changes and new phenotype expression after polyploidization.
