植物抗病基因研究的CiteSpace可视化知识图谱分析

Visual Analysis of CiteSpace Knowledge Map in the Research on Plant Disease Resistance Genes

为更系统地了解中国植物抗病基因研究趋势和热点问题,以CNKI数据库核心期刊为数据源,采用CiteSpace工具,对1991—2021年发表的植物抗病基因相关文献进行计量和可视化分析。结果表明,植物抗病基因相关文献的年发文量整体呈现逐年上升的趋势;各研发单位中发文量最多的是中国农业科学院植物保护研究所,共发文86篇;期刊《中国农业科学》刊登文献数最多,共87篇;发文量最多的作者为河北农业大学的刘大群,共发文38篇;关键词共现分析中出现频次最高的关键词为“抗病基因”,共出现226次;突现词分析中突现强度最大的关键词是“无毒基因”(9.707)。植物抗病基因的研究热点主要集中在农作物病害的防治、抗病基因研究的技术手段、抗病性相关的化学成分三个方面。

This study aims to systematically understand the research trends and hotspots of plant disease resistance genes in China.Taking CiteSpace as the tool,the core journals of CNKI databases were used to carry out quantitative and visual analysis of literature related to plant disease resistance genes published from 1991 to 2021.The results showed that the number of publications on plant disease resistance genes increased year by year on the whole.The Institute of Plant Protection of the Chinese Academy of Agricultural Sciences had the highest number of publications among all research institutes,with a total of 86.It was the the journal of Scientia Agricultura Sinica that published the most literature,with 87 publications.With 38 articles,Liu Daqun,from Hebei Agricultural University,published the most.Based on the co-occurrence keyword analysis,the highest frequency keyword was“disease resistance genes”,which appeared 226 times in total.In the analysis of emergent words,the keyword with the highest intensity was“avirulence genes”(9.707).There are several hotspots for plant disease resistance genes,including the prevention and control of crop diseases,the technical means of disease resistance gene research,and the chemical components related to disease resistance.
