Abstract:
Objective:To analyze the overall layout of coronavirus genetics research in the past 20 years from the perspective of publication time, journals, keywords, citations and funds, identify core research institutions and their cooperation networks in this field, and explore current research hotspots.Methods:PubMed and Web of Science databases were searched separately for the research literature and citations data about coronavirus genetics from 2003 to 2021, and Excel was used to analyze the distribution of the literature and institutions, and then the Citespace software was selected for institutional cooperation network and reference co-citation cluster analysis.Results:The literature about coronavirus genetics had increased significantly in 2020. The top 10 journals have collected 23.4% of relevant literature. Chinese Academy of Sciences has published the most documents in this field, in the top 10 high-yielding institutions, 7 are from China. In the cooperation network, the Chinese Academy of Sciences, University of Hong Kong and University of Sao Paulo have high betweenness centrality. The total litation times and average citation times of funded papers were higher than those of non-funded papers. There have been 7 research hotspots in the past 20 years. The research on " the gene sequence and functional receptors of the Middle East respiratory syndrome coronavirus" , " the gene traceability and drug development of the SARS-Cov-2" as well as " genotyping, origin and economic impact of paroxysmal porcine epidemic diarrhea virus in the United States" are still active in the past five years.Conclusions:Coronavirus genetics research will be at a sustained high level in the next few years or even longer. It is difficult to publish papers in journals with high impact factors (IF>5.00) in related fields. Chinese research institutions are active in this field. The Chinese Academy of Sciences and the University of Hong Kong are the most influential, and they have the closest cooperation with other institutions. The genetic tracing, gene sequence and functional receptor of coronavirus and drug development are likely to be the forefront of the research in this field.our govermment should advance the layout in this field and increase the number of research funds and financial support.
