基于Web of Science数据库禾草内生真菌生物碱论文计量统计分析

A bibliometric analysis of research on the role of alkaloids produced by grass endophytic fungi based on the Web of Science database

禾草内生真菌生物碱可以增强寄主植物的抗逆性,为了解禾草内生真菌生物碱的研究现状和发展趋势,基于Web of Science数据库,对20年来(2000-2019年)国内外发表的禾草内生真菌生物碱论文进行检索筛选,以禾草内生真菌生物碱为关键词,共检索到646篇相关文献,其中我国33篇。对相关文献进行计量学分析发现:生物碱发文数量排名前三的国家是美国、新西兰和中国;文献平均被引次数最多的是中国;20年来,我国关于禾草内生真菌生物碱的文章数量稳步上升,且不断有文章被国际高水平的期刊发表。我国禾草内生真菌生物碱的研究单位主要集中在兰州大学和南开大学等高校,研究内容主要是生物碱生物学特征、生态作用以及影响共生体产碱的因素等。而关于生物碱致毒机理和人工合成途径的研究较少,今后需加强对其的深入研究。

Alkaloids produced by grass endophytic fungi have the ability to enhance resistance to a wide range of stress environments faced by the host plant.We reviewed the status and developing trends of research into alkaloids of grass endophytic fungi,based on the Web of Science database.Papers about alkaloids of grass endophytic fungi published in the past 20 years from 2000 to 2019 were retrieved and screened,with Epichloëalkaloids or Neotyphodium alkaloids as keywords.The papers retrieved numbered 646;33 reported domestic research in China.According to the quantitative analysis of the retrieved papers,the top three countries for the number of alkaloid publications were the United States,New Zealand and China.China was the country with the most citations on average.Over the past 20 years,the number of articles on endophytic fungal alkaloids in China has been steadily increasing,and some articles have been accepted by international journals at a high level.The laboratories researching endophytic fungi in grasses in China were mainly concentrated in Lanzhou University and Nankai University.The research outputs primarily included biological characteristics of alkaloids,ecological functions and factors affecting alkaloid production in symbionts.However,there are some studies on the mechanism of alkaloid toxicity and the biological synthetic pathways of alkaloids,which potentially could form a foundation for development of new technologies for human benefit.
