【目的】马铃薯Y病毒属(Potyvirus)是世界上最大的两个植物病毒属之一,对多种农作物造成危害。利用文献数据库,客观地分析国内外Potyvirus研究的发展动态,为国内外Potyvirus科研工作者和决策者提供参考。【方法】基于Web of Science数据库,采用文献计量学方法,对全球发表于1985 2012年的Potyvirus文献的国家、作者、机构、载文期刊及研究内容进行了数量和质量分析。【结果】检索到全球60个国家发表的Potyvirus文献2 442篇,以及每篇文献的被引频次和每个国家、机构及作者的H指数。经分析得出:全球Potyvirus研究论文的产出量自1991年呈稳定上升趋势,文献的数量和质量在统计的国家中,以美国最好,其次是法国、西班牙、澳大利亚、英国;美国的高产活跃作者最多;Potyvirus研究的热点是基因沉默和分子生物学,并随着研究技术方法的革新将不断深入;研究方向更多倾向于寄主方面的研究(如基因沉默、寄主抗性、与寄主互作等)及交叉学科;而中国在Potyvirus基础研究上距离国际先进水平还有很大距离,研究力量较少,有影响力的论文较少。【结论】美国在该领域的研究处于领先水平,我国仍需加强Potyvirus基础研究力量投入,努力缩短差距。
【Objective】 Potyvirus is one of the two largest genus of plant viruses in the world, which is harmful to many kinds of crops. By using the literature database, this paper objectively analyzes the development of Potyvirus research at home and abroad and provides reference for Potyvirus researchers and decision-makers at home and abroad. 【Method】 Based on the Web of Science database, bibliometrics was used to conduct quantitative and qualitative analysis of the countries, authors, institutes, periodicals and research contents of the Potyvirus published in the world in 1985-2012. 【Results】 A total of 2 442 Potyvirus papers were published in 60 countries worldwide, and the citation frequency of each literature and the H index of each country, institution and author were retrieved. The analysis shows that the output of the global Potyvirus research papers has been increasing steadily since 1991, and the quantity and quality of the literature are the best in the statistical countries, followed by France, Spain, Australia and the United Kingdom; Most active authors; Potyvirus research focuses on gene silencing and molecular biology, and with the research methods innovation will continue to deepen; research direction more inclined to host research (such as gene silencing, host resistance, and the host mutual Etc.) and interdisciplinary subjects. However, China still lags far behind the international advanced level in basic research on Potyvirus, with less research power and less influential papers. 【Conclusion】 The research on the United States in this field is at the leading level. China still needs to step up its efforts in basic research on Potyvirus and strive to shorten the gap.
